Flamingos are trending and in this tutorial I’ll show you two simple techniques to make stunning, unique flamingo cakes!
Make a pink cake
I’m using my strawberry cake recipe so that the insidewill be pink just like the flamingos on the outside. For the maximum strawberry flavour I’m using the strawberry buttercream from the recipe as my crumb coat. After refrigerating it for 30 minutes it’s firm and I can add a gorgeous ombre frosting on top.
Add turquoise ombre frosting
Ombre is secretly very easy to do. Use the lightest colour on top of the cake, spreading it around the top of the sides, too. Then use the darkest colour at the very bottom of the cake, spreading it right down to the cake board. Of course, you can do the opposite instead, with the darkest colour at the top and the lightest at the bottom. Now mix the lightest and darkest colour together to make a middle shade. Spread thisaround the middleof the cake, between the other two.
Wiggle your spatula up and down in zig zags around the cake to blend all of the shades together slightly. This will make a gradual gradient of the colours.
Then scrape around the cake with a cake comb to smooth the frosting. It’s simple but such a stunning background to make any cake design a bit more detailed and interesting.
Tidy up the top edge and then put the cake into the fridge to chill and set the frosting. Both of the flamingo techniques in this tutorial need the frosting to be firm before you decorate it.
How to make a mosaic flamingo cake
Prepare buttercream mosaic tiles
For the first technique, which is my favorite, we’re going to make a flamingo mosaic. Spread coloured buttercream onto parchment paper on top of a small, flat surface. This could be a cutting board, cake board, upside down tray or a baking sheet. You need to be able to fit it in your freezer later.
You’re aiming for thin, smooth patches of colour. Ideally, all of the colours will be the same thickness. It’s best to do this on at least two separate pieces of paper so that you can chill them separately. You’ll see why later.
Put the coloured buttercream into the freezer for about 15 minutes to chill and firm up. Then use a sharp knife dipped in warm water to slice through the frozen buttercream, cutting it into little tiles of different shapes and sizes.
After a few minutes at room temperature the buttercream will soften and get sticky. You need it to stay firm so work quickly to slice it. Dip your knife into the warm water in between cuts to clean it and then wipe it dry on a towel or paper towel before you cut again. This will give you the neatest edges on your tiles.
Outline a flamingo on the cake
Draw a flamingo or trace one, making sure it will fit on your cake. I used four 6 inch layers to make my cake so it's tall! I used my strawberry cake recipe which can also be used for a three layer 8 inch cake but by making 4 smaller layers I have a taller cake with more space on the sides for my flamingo. Of course, you could do this on the top of the cake instead. However, since the sides of a cake are more visible, I like to put my decorations there.
Cut the flamingo out and then take your cold cake out of the fridge and position the paper flamingo on it. Trace around it using a toothpick to draw a very faint outline. Since the frosting on the cake has set, it’s firm and won’t get damaged by the paper. Brush off any buttercream crumbs along the outline using a paintbrush.
Attach buttercream mosaic tiles to the cake
Brush the entire flamingo shape with a paintbrush dipped in water and then blotted on a towel or paper towel. You want it to be damp, not dripping wet. The moisture will help the frozen buttercream stick to the frosting.
Take your buttercream tiles out of the freezer and pick one up. Press it against the cake, within the outline you scored with your toothpick. Continue with more tiles, using different colours and shapes and sizes for lots of variety. Make sure you’re going right up to the outline so that your shape is recognizable.
I used a little black buttercream triangle for the beak and a tiny black triangle for the eye. You can cut the tiles now into smaller pieces or different shapes to fit into little spaces between other tiles.
The buttercream tiles will get soft as they warm up to room temperature. You’ll notice because they’ll start to stick to your finger instead of the cake. The tiles will also warp and droop because the buttercream isn’t firm anymore. When that happens, put these colours back into the freezer to chill and firm up again. Take out another colour and use those tiles instead. That’s why it’s a good idea to spread the colours onto at least two different pieces of paper. You can move them around separately and don't waste time waiting for any buttercream to chill.
Minimize condensation
Since the cake has been in the fridge it will be cold. If the room is warm, you might notice beads of condensation forming on the cake. It’s important to dab those with a paper towel to absorb them and leave the frosting dry. If you don’t, the colours of the buttercream tiles can run, especially dark colours like the beak and the eye. I recommend adding the beak and eye last for that reason, so that the back colour doesn’t run. If the room is warm, blot the condensation droplets and then put the cake in the fridge for 15 minutes before continuing.
The mosaic flamingo is the first technique of this tutorial and I’ll show you the end result in a minute. Keep reading for the second technique!
How to make a floral flamingo cake
Make a flamingo stencil
For the second technique, make your own flamingo stencil. Trace your drawing or an image of a flamingo onto parchment paper or wax paper and then cut it out. Leave the paper around the shape intact to use as your stencil.
I’m going to cut a separate stencil for the other leg because if I cut the second legs out now, I'd have a big triangle instead of two dainty legs!
Wrap your stencil tightly around the cake and use pins to attach it so it doesn’t move. Spread frosting over it to cover the parts you cut out of the paper.
Then use an offset spatula or cake comb to scrape over the frosting. You'll take off the excess to leave a thin, flat layer. Peel the stencil off and a smooth flamingo will be left behind on the cake!
For the bent leg, put the cake back into the fridge for 30 minutes. You need to set the first part of the design so that it's firm. Then press on another piece of paper with just the bent leg. Spread buttercream over it, smooth it, and peel the stencil off.
Make a floral flamingo body
Now, what about the body? To give it some texture and depth I’m making pink wafer paper flowers. I teach how to do this in my Layer Up program on my cake school. You could use real or artificial flowers instead or pipe rosettes with a 1M tip and pink buttercream.
Add details to the flamingo cake
I’m adding a wave border around the bottom of the cake with the leftover turquoise frosting from the ombre. This is a #104 petal piping tip and the way you hold it is important. The narrow end of the teardrop shape of the petal is pointing away from the cake to make the thin edge of the piping:
Meanwhile, the wider end of the tip is pressed against the cake to make a thicker edge. This thick edge will attach to the cake to secure the piped border.
So, which flamingo do you prefer? Stenciled with a floral body or a mosaic version? Tell me in the comments!
Here are the most common cake fails and what to do to prevent or fix them!
#1 Sliding cake fails
What cake fails are possible if cakes aren't attached to their cake boards? When you frost the cake, your offset spatula and cake comb can push the cake around. If the cake doesn't stay still it's really difficult to frost.
So, before you start layering cake and fillings, pipe or spread a dot of buttercream in the middle of your cake board.
Press your first cake layer down onto that dot. When it sets later, it will attach the cake to the cake board. Put the cake in the fridge for 30 minutes to chill, which will make it set more quickly. Then you can do any cake decorating you like without needing to chase your cake around on the turntable!
#2 Cake fails because of buttercream consistency
The biggest cake fails are caused by the wrong consistency of buttercream. You'll know if it’s too runny because it will slide down the cake. Even if you spread it up to the top of the cake, as you smooth the frosting it will sink down. You’ll have these big indents around the top edge:
If the buttercream is too stiff it will be difficult to spread over the cake. The buttercream will tear apart from itself, leaving these holes all over the surface of your frosting.
To achieve the right consistency and prevent air bubbles, use this easy hack. Scoop up a third of the buttercream and microwave it for 10 seconds to melt it.
Stir it back into your bowl of buttercream and after a few stirs you’ll have silky smooth buttercream. This method also gets rid of any air bubbles in the buttercream! The buttercream will spread effortlessly onto your cake and will be quick and easy to smooth.
The right consistency is key to smooth frosting, neat piping, stenciling, and really any cake decorating technique.
#3 Don't use room temperature cake layers
The temperature of your cake layers really matters when you’re assembling and frosting your cake. If you don't let cakes cool after baking they'll be delicate and crumbly. When you spread filling onto the layers it will pull up crumbs from the cake, which will get into your filling. Your crumb coat will be filled with crumbs, too!
But the bigger problem is that as you frost the cake, the pressure from your spatula and cake comb will push the cake layers sideways. This will make the cake lean, like this:
Instead, put your cake layers in the fridge for 30 minutes or the freezer for 15 minutes before you assemble and frost your cake. When they’re cold they’ll be less crumbly and much firmer and easy to frost. Even this tall, four layer cake is standing straight as I spread buttercream onto it:
Don't worry - when cakes warm back up to warm temperature they’ll soften again. They'll be just as delicious as before they went into the fridge!
#4 Runny fillings
Runny fillings like jam or caramel are delicious but tricky for two reasons. The first is that the weight of the upper cake layers will push down on the filling. They'll squeeze it out of the sides of the cake, which can cause bulges in your frosting. Look at the jam oozing out here.
The second is that these fillings are slippery. They don't attach to the cake layers like buttercream does. When you frost the cake your spatula or cake comb can push the layers off-center, making the cake lean.
Now, this doesn't mean you can’t use runny fillings! You just need to add an extra step: a buttercream dam. These are rings of buttercream piped around the edge of each cake layer, like a dam or wall. They'll hold the runny filling in so that it doesn't ooze out.
Now spoon your next filling into the middle of this and spread it up to the edges of the buttercream dam. Optionally, spread a thin layer of buttercream onto the cake first to stop the filling absorbing into the cake. Then put the cake into the fridge for about 30 minutes to chill and set these buttercream dams. When you frost the cold cake, the cake layers and the filling will both stay in place.
#5 Support for tier cakes
If you stack cakes without support, within a few hours the top cake will sink down into the bottom cake. This will happen even faster if the cake’s haven’t been chilled!
Here's how to stack a tier cake so that this won't happen. First, chill both cakes in the fridge for a few hours to set the frosting. This is necessary so you don’t damage them as you stack them. The top cake needs to be on a cake board that’s the same size as the cake so that you don’t see the board after you stack the cakes.
Lift the top cake and center it on the bottom cake. Use a toothpick to outline the cake and then take it off. Cut five straws or wooden dowels to be the same height as the bottom cake. Use the first straw or dowel to measure the others to be the same height.
Push the straws or dowels within the circle you scored onto the cake with your toothpick. I use a square formation with one more in the middle.
Spread some buttercream within the circle you scored to act as glue. Then put your next cake on top, still on it’s cake board. You can cover up the join of the two cakes with a piped border if you like.
For a three tier cake, repeat the process for your second tier. The supports will hold the cakes upright and the buttercream glue will stop the top cake from sliding around when you move it.
#6 Leaning cake fails
Remember this leaning cake from earlier in this tutorial? Here’s a quick fix for leaning cakes that haven't been chilled yet. It works when the filling hasn't set so the layers aren't fixed in place. While you’re frosting the cake, as you notice it leaning, wrap the cake in cling film or Saran Wrap. Then push it to straighten it.
Put it into the fridge to set the filling and frosting so that the cake is stable, which will take about 30 minutes. Then take the cake out and unwrap it. Since the frosting has set, you won't damage it as you unwrap it.
Now that the cake isn'tleaning and it’s firm, add another layer of frosting on top. You'll have a neat, straight cake!
#7 Textured frosting
When you smooth the frosting on a cake you only need a very thin layer to cover the crumb coat. However, that’s not true for textured frosting. With a textured cake comb the frosting needs to be at least as thick as the texture on the comb. If it's not, as you scrape around the cake to imprint the texture in the frosting, the comb will go too deep. The widest parts of the texture will push through the final layer of frosting an into the crumb coat underneath.
So for textured frosting, making sure you spread the frosting at least as thick as the texture in the comb.
#8 Cake toppers
After all the effort of getting your frosting smooth, don’t ruin it by rushing into the decorations! This is especially true for heavy cake toppers or piping. Their weight will cause bulges in the frosting since the frosting is still so soft, which you can see here:
Chill the cake after frosting it for at least 30 minutes in the fridge so that the frosting gets firm. After that you can add piping, cake toppers, or any other heavy decorations.
#9 Melting cake fails
You might have seen this video I shared on instagram that went viral. It shows what happens when a cake is left in the sun on a cool day at 70F or 22C:
I keep my cakes in the fridge if they’re not going to be eaten within a few hours. It keeps the frosting and decorating stable and also keeps the cake fresh for longer. The frosting seals in the moisture of the cake so the cake doesn't dry out. For more than a few hours in the fridge, put it in a box or cake caddy so it doesn’t absorb any flavours in the fridge.
Keep cakes in the fridge until you transport them. Cold cakes are firmer are more resistant to vehicle vibrations or sudden braking. If you transport cakes at room temperature they're more likely to develop leans or bulges in the frosting.
#10 Servings cakes
Although I recommend storing cakes in the fridge, I don't recommend eating them cold! Cold cakes taste hard and dry. Take cakes out of the fridge 2-4 hours before serving and leave them on the counter to room temperature. When the cake and buttercream warm up they'll be soft and moist and delicious!
Russian piping tips pipe all of the petals of a flower, in several colours, with just one squeeze! They’re easy to use once you know how so in this tutorial I’ll share 6 hacks for Russian piping tips!
How do you use Russian piping tips?
Russian tips are bigger than standard piping tips so you’ll need to cut larger holes in your piping bags. I like to cut a little bit less than half way up the tip. With the tip pushed to the end of the bag, score a line about a third of the way up. Push the tip out of the way and cut along that line. Now it should fit snugly and won't pop out while you're piping.
The technique for piping with Russian piping tips isn't complicated. However, you won't be successful unless you use these six hacks before and after you pipe.
#1 The right buttercream consistency for Russian piping tips
Maybe the most important hack is to get the right consistency of your frosting. This is my 4 Minute Buttercream and you should be able pull a spatula through it easily to stir it. You'll leave texture behind that holds its shape and doesn’t sink back down into the buttercream.
This is what a flower looks like when buttercream has the right consistency.
Buttercream will be too stiff when it’s too cold or there’s too much sugar in it. It will be difficult to squeeze through the tip and the petals might pull away with the tip instead of sticking to the cake. You'll notice jagged edges on your petals.
Buttercream will be too runny when it’s too warm or there’s not enough sugar or too much milk in it. The petals will lose their definition and blob together.
Fix buttercream consistency by adding more milk to stiff buttercream or more sugar to runny buttercream.
#2 Using Russian piping tips with several colours
One of the biggest advantages of Russian piping tips is that they pipe different petals in different colours. But how do you get different colours into a piping bag? I like to drop the piping bag into a tall glass or cup. Fold the top over the rim to hold it open. It’s easiest if the bag is pulled tight, with the tip visible at the bottom of the glass.
Spread your first colour around the piping bag, pushing it against the glass to cover the bag all the way around. Spread it all the way down to the piping tip. You want a fairly thick layer so that the outer petals will all be this colour.
You can layer another colour or two on top of this using the same spreading tehcnique. For a quicker option, spoon your next colour in and push it down to the bottom of the the bag. You want it to go all the way down to reach the piping tip.
Now pull the bag out of the glass and twist it to push the buttercream down. When you squeeze the bag you should see the colours coming through the piping tip.
If you don't push any colours down to the piping tip, they won't come through the tip when you pipe. This is most common with the middle colour. If this happens, squeeze the bag until you see all the colours coming through and now you’re ready to pipe!
#3 How to pipe onto cakes with Russian piping tips
Before you pipe with Russian tips onto a cake, the frosting should have set. Put the cake into the fridge for about an hour and it will get cold and firm. Now when you pipe onto the cake you won’t cause any bulges in the frosting.
#4 Prevent buttercream crusting
After chilling the cake, the frosting won't be sticky anymore. That means you really need the frosting in the piping bags to be sticky. Otherwise, the flowers you pipe won’t stick to the cake because they'll pull away with the piping bag.
This happens when you leave piping bags out for about 30 minutes. The exposed buttercream at the tip crusts. which means it gets hard and loses its stickiness. Squeeze the bag to push the crusted buttercream out through the piping tip. The buttercream left in the piping bag will be soft and sticky and ready to pipe!
To prevent crusting, cover Russian piping tips with plastic wrap when you’re not using them for long periods of time.
#5 Don't let buttercream get too warm for Russian piping tips
Piping with Russian tips is very straightforward - it’s the consistency and that seems to cause the most problems. When the consistency is right, the flowers will stick to the cake and the petals will pull out and break away neatly from the piping tip, leaving gorgeous flowers behind on the cake.
But as you keep piping flowers, you might notice the petals getting less defined as the details merge together. This happens when your buttercream gets too warm, usually from the warmth of your hands as you pipe.
Put the whole piping bag into the freezer and set a timer for 1 minute. This is enough time for the buttercream to cool back down and firm up.
Then pipe and notice how much more defined your flowers are!
#6 Fix messy petals
Sometimes petals will be too long if you squeeze the bag with a bit too much enthusiasm. There’s a hack to fix drooping petals and it’s simple: Use a toothpick!
Hold it where you want the petal to end and spin it as you push up. You’ll lift away the extra part of the petal, leaving a neat edge behind on the remaining petal.
I hope these hacks for Russian piping tips have been useful! Ask me any questions in the comments and visit my cake school to learn hundreds of cake decorating techniques and designs.
There are so many tricks with toothpicks for cake decorating! Make neat patterns on cakes, smooth stenciling, stable tier cakes, really white buttercream and more! In this tutorial I'll share 10 ways to use toothpicks for cake decorating.
#1 Create guides for piping
Toothpicks can guide you as you're piping, showing you where to move your piping bag. Start by cutting a circle of parchment paper that's the same size as your cake. You can use wax paper or baking paper or even normal paper instead. The quickest way to measure the paper is to trace around the cake pan you baked the cake in.
Cut the circle out and fold it in half three or four times or more for really big cakes. Unfold it and place it on top of your cake.
Use the creases in the paper as your guidelines, poking toothpicks into the side of the cake below each crease. Now when you pipe, the toothpicks will keep your designs spaced evenly around the cake.
#2 Mark outlines for cake designs
Take this a step further by using toothpicks to create outlines for your cake designs. Score your design onto a frosted cake, drawing freehand or tracing around objects or cut-out paper shapes.
Outlining a shape with a toothpick gives you a subtle guide that helps you create the right proportions.
Once it's covered up, in this case with buttercream mosaic tiles, you really don't notice the toothpick outline. You can outline messages, too, to make sure the letters fit before you pipe them.
#3 Stack tier cakes using toothpicks
To stack a tier cake, outline where the top tier will go before adding support straws or dowels below. The cakes need to be cold and firm so put them in the fridge for a few hours first.
Push support straws or dowels within the circle you scored onto the cake with your toothpick. This way you'll know they'll be positioned underneath the cake above, to support it. Doing this for every tier will make sure your cakes are centered and won't sink.
#4 Toothpicks for cake decorating marble cakes
To make marbled cake batter spoon different flavours into a pan, alternating between them. You can do this with different colours instead, spooning or piping them into the pans.
The key to making this marbled is to use a toothpick, dragging it through the cake batter. You'll mix the colours together just enough to create this fun, marbled effect.
#5 Toothpicks for cake decorating with smooth transfer designs
Make designs really smooth with a toothpick when you pipe them to later transfer to a cake. Use dabbing motions to push the buttercream downwards towards the paper or acetate underneath. This will prevent trapped air pockets that later become holes or indents in the surface of the frosting.
This works for character cakes made with buttercream transfers, like this cake:
Use toothpicks to create 3D designs on cakes by making your own edible cake toppers. Melt chocolate and spoon it into a sandwich bag, cutting off one of the corners to pipe through. Next, write a message or draw a shape onto parchment or wax or baking paper.
Then push a toothpick into the bottom of each section, piping some more chocolate to cover it up.
Pour sprinkles or coloured sugar on top, pressing it gently into the melted chocolate. The chocolate will set after about an hour at room temperature or 30 minutes in the fridge.
Then you'll be able to pick them up and push them into the cake so that they stand upright. So pretty!
#7 Toothpicks for cake decorating mistakes
Toothpicks are ideal for tidying up messy frosting. For example, stenciling can be tricky but with a toothpick you can make smooth, neat, stenciled designs.
If the stencil moves while you're spreading and smoothing the frosting over it, you'll have smudges around the outline. A toothpick is perfect for scraping those off.
Also, as you peel a stencil away from your cake the frosting you've just spread over it might try to pull away with it. Nudge it with your toothpick straight away before the frosting sets. With straight, smooth edges around stencil shapes the design will look much neater.
Use toothpicks to tidy up piping, too by taking off any part you don't like.
You can also nudge details into the right position with toothpicks to make your piping look much better.
#8 Toothpicks for cake decorating patterns
To create a symmetrical pattern, measure a piece of parchment or wax paper so it will wrap around your cake. Then fold it in half and half and half again in both directions if you need a grid. It's useful to mark the places you want to pipe your pattern with a pencil like these polka dots here.
Wrap the grid around your cake and use a toothpick to poke through each point. You'll need to chill the cake first so the frosting has set and it's firm.
Peel the paper away and then pipe over the points you marked on the cake, making a neat symmetrical pattern.
#9 Carve details with toothpicks
Use toothpicks to add tiny details to designs like facial features that would look messy with thick piping instead. Chill the cupcake or cake before you do this so that the frosting is firm. Your toothpick will carve through the buttercream, leaving neat lines and dots behind.
#10 Make white buttercream
Toothpicks are a game changer to make really white buttercream even if you're using yellow butter. Dip a toothpick into violet gel so that you can add just a tiny amount to your buttercream. The blueish tint of the violet will offset the yellow in the buttercream to make a brighter white.

In this bubble wrap cake tutorial I'll show you how to make bubble wrap frosting and how to fill the dots with rainbow colours.
Make a rainbow checkerboard cake
To make rainbow cake layers, weigh the cake batter to divide it into six equal portions. Then add gel colours to each one. To use just one bowl, mix the colours in this order: yellow, orange, red, purple, blue, green. This way you don't need to wash the bowl in between colours.
After baking and cooling the cake layers, make a checkerboard pattern by cutting discs out of each layer. Choose objects with the same difference in size, for example for these 6 inch cake layers I'm using a 4 inch plastic cup and a 2 inch cookie cutter.
Since the cakes darken around the edges I'm trimming those parts off. Now mix and match to make colourful rings of cake and layer the cake with filling.
The bubble wrap design needs a smooth surface to attach to so start by frosting the cake. If you'll have white frosting in the design, cover the cake in two layers of frosting. Otherwise, you might see the colored cake layers through the white parts of the design.
Make bubble wrap frosting
Now spread frosting onto a piece of bubble wrap that you've washed and dried so it's clean. You'll need a piece at least as tall as the cake and wide enough to wrap around it. You can tape separate pieces together if you don't have a piece big enough. I'm spreading the frosting about a centimeter higher than the cake and a few centimeters wider to make sure it completely covers the cake.
If you can see any shadowing of the bubble wrap through the frosting, that means the frosting is too thin. Smooth it a few times to make it flat and level. Then pick it up and wrap it around your cake. It's best to chill the cake in the fridge for about an hour first so the cake and frosting are firm. This way they'll hold their shape even as you push the bubble wrap against the cake.
Push along the join where the bubble wrap overlaps and then put the cake in the fridge for an hour. When you peel the bubble wrap off you'll have this gorgeous unique bubble wrap texture in the frosting!
Use a sharp knife to trim off the extra buttercream from the seam to leave it smooth. Also trim off the frosting that's sticking up above the top edge of the cake.
I'm using the end of a paintbrush to push in some bubble wrap holes that haven't imprinted the frosting properly. You could leave the cake like this or fill in the bubble wrap holes with colour. Put the cake into the fridge until you're ready to add more decorations.
Make a rainbow bubble wrap cake
For these small amounts of frosting I like to mix the colours in a cupcake or muffin pan. It's an easy way to make cleanup time quicker instead of washing lots of little bowls. Tint the frosting in the same order as the cake batter: yellow, orange, red, purple, blue, green. This way you don't have to wash your spatula in between colours.
When you're ready to add the colours to the cake, take the cake out of the fridge. Count the number of rows of bubble wrap dots and divide that by your number of colours. This way you'll cover the same number of rows for each colour to space them evenly down the cake.
The cake will warm up after a few minutes out of the fridge so the bubble wrap pattern will get softer. But you need it to be firm so that these colours fill the holes instead of squashing them. So spread the colours over the bubble wrap frosting as quickly as you can. I've overlapped the colours to make a rainbow gradient rather than distinct stripes of colour.
Scrape around the cake with a cake comb until you like the effect. I love the way the colours look on my cake comb as I scrape them off!
A metal cake comb is ideal because you can heat it with hot water or a blow torch. Then it will scrape off the excess buttercream really easily without needing to use much pressure. The more you scrape the colours off, the more white you'll have in the design.
To get the top edge of the cake sharp use a knife to cut off any frosting that's sticking up. This way you won't smear streaks of red onto the top of the cake.
Make rainbow chocolate spheres
To make colourful spheres to decorate this cake, use white chocolate. Heat it in a microwave safe bowl for 1 minute at 50% power so that it doesn't seize. Divide it into bowls and tint each one using oil-based colours. Buttercream colours won't work because the water in them will make the chocolate stiff and grainy.
Use the back of your spoon to coat a silicon mold with the coloured chocolate. Of course, you'll need two hemispheres for each sphere. Try to nudge the chocolate up to the top edge so it's thick there, which will help you attach them together next.
Use an offset spatula or cake comb to scrape any chocolate off the rest of the mold.
Put the molds in the fridge to chill the chocolate so that it hardens. Then pop the chocolate out of the mold by pulling the sides away from each hemisphere.
Hold a plate under hot running water to heat it and then dry it off. Place the chocolates on the plate to melt the edges.
Then press them together to make spheres. It's best to wear gloves for this so that you don't leave fingerprints on the chocolate, which will dull it.
Decorate the rainbow bubble wrap cake
To attach the chocolates to the cake you can either use a dot of buttercream or melted chocolate. Both will set onto the cold cake and act as glue to stick the chocolates in place. Buttercream will be the most secure when it's cold so if the cake is going to be out of the fridge for more than 1 or 2 hours I would use chocolate instead.
This would look great with the chocolate spheres in all of the colours of the rainbow frosting. I only have these oil-based colours so here they are!
This cake is so colourful and unique, both on the outside and the inside.

This strawberry cake, filling and frosting are bursting with strawberry flavour and there are two types of strawberry ingredient that make it taste so perfect.
How to make strawberry cake
Just like with any cake, all of your ingredients need to be at room temperature. Take your eggs, milk and butter out of the fridge a few hours before you start baking.
This is an easy strawberry cake recipe with just a few steps. Before you start, whisk the dry ingredients (flour and baking powder) together and mix the wet ingredients together, too. These are milk, vanilla and blended strawberries. This recipe uses two kinds of strawberries: fresh or frozen and also freeze-dried strawberries. This will give you the maximum fresh strawberry flavour and colour without making the cake heavy or dense.
Now it's time to put it all together. Mix the butter and sugar together at medium speed for about 3 minutes until it's light and creamy, like this:
Add the eggs one at a time, mixing for about 30 seconds after each one. This will make your cake light because the ingredients are properly mixed together.
Scrape down to the bottom of the mixing bowl with a spatula to make sure there aren't any clumps of sugary butter stuck to the bottom. Then add a third of the flour mixture, mixing only until it's blended in.
Then add add half of the strawberry mixture and mix that just until it's incorporated, too. This cake batter will be pink from the strawberries but if you want it to be pinker you can add some food colouring.
Mix in another third of the flour, then the rest of the strawberry mixture and then the rest of the flour mixture.
How to bake a strawberry cake
Divide the strawberry cake batter between two or three 8 inch pans. I like to use three so there are more layers of cake and also more layers of filling.
If you want a smaller, taller cake you can use the same recipe in four 6 inch cake pans. This makes a really elegant cake with lots of space on the sides to add decorations. More about that, later in this tutorial!
Tap the pans on the counter to level the batter and then pop these into the oven. Bake 23 minutes at 350° F or 175° C. When the cake springs back up when you poke it, the cakes are baked. Don't bake any longer than this or the cakes will dry out.
Let the cakes sit in the pans for 5 minutes to cool slightly. When you can touch the pans without an oven glove, then turn over onto to a wire rack. Leave them for about 2 hours to cool completely.
How to make strawberry buttercream
Meanwhile, make the most delicious strawberry buttercream! Mix butter and powdered sugar or icing sugar on the lowest speed to prevent air bubbles in the buttercream. Add freeze-dried strawberries, blended into a fine powder for a smooth buttercream. Using freeze-dried strawberries instead of fresh strawberries gives you all the strawberry flavour without making the buttercream too runny. Finally, add 1 to 2 tablespoons of milk to thin the buttercream out slightly. This will make it easier to spread onto the strawberry cake.
This strawberry buttercream is so delicious, you can eat it out of the bowl with a spoon! It also tastes incredible paired with my Very Vanilla Cake.
Layer strawberry cake and strawberry filling
Once the cake layers have cooled, spread a bit of buttercream onto a cake board or plate or platter. This will attach the first cake layer and hold the cake still when you frost it next. Pipe or spread some buttercream to cover the cake, which will be the filling. The smell is so good with the two types of strawberry ingredients in the cake and also in the buttercream. Yum!
Lower the next cake layer down on top, lining it up straight. Pipe or spread on some more buttercream and finish with the top layer. I like to place the top cake layer upside down with the flattest, least crumbly side facing up.
Cover the whole cake with more strawberry buttercream. Since this isn't a crumbly cake, the strawberry frosting will glide over the cake and you don't need a crumb coat!
My favourite way to decorate this rustic style strawberry cake is with texture. This means you don't need to be a master at smooth frosting! Scrape around the cake with a cake comb or your offset spatula to smooth the frosting slightly and then use the back of a spoon to add texture. You can drag the spoon upwards or sideways around the cake, or in little curves or arc shapes.
You can decorate this with fresh strawberries or freeze-dried strawberries, or both! I love the way freeze-dried strawberries look and they won't leak any strawberry juices onto your cake.
If you want to decorate the cake with a theme using different colours and styles, use the strawberry buttercream as a crumb coat. Let it set in the fridge for about 30 minutes before adding different frosting on top. This way you'll have all of the flavour of the strawberry buttercream but whatever unique decorations you like. For the Flamingo cake below I baked this recipe in four 6" pans and used three quarters of the strawberry buttercream recipe for the filling and crumb coat.
How to move a cake onto a cake stand or platter
If you frosted the cake on a cake board, you can move it onto a platter or cake stand. Put the cake into the fridge for an hour or two to set the frosting so it's very firm. Then slide a spatula underneath it to separate it from the board. Spin the spatula all the way around, between the cake and the cake board. Then lift the cake up and lower it down onto the cake stand. I spread a bit of buttercream on the cake stand to attach the cake so it doesn't move when I lift it.
You can keep this cake in the fridge for a day or two before serving it. Take it out of the fridge at least two hours before you serve it so that it warms up to room temperature. That's when the cake and buttercream will taste the best.
The fresh and freeze-dried strawberries make the cake taste just as full of strawberry flavour as the buttercream and it's just heavenly! I hope you love this fresh strawberry cake as much as I do.

This cake, filling AND frosting are bursting with strawberry flavour!
Ingredients
UnitsScale
For the strawberry cake:
1cupunsalted butter
2cupssugar
4 eggs
3cupsall-purpose flour (plain flour)
2 teaspoons baking powder
1/2 teaspoon salt
1/2cup whole milk (full fat)
3/4cup fresh or frozen strawberries
1cup freeze-dried strawberries (15g)
1 teaspoon vanilla
For the strawberry buttercream:
2cupsunsalted butter
6cupspowdered sugar (icing sugar)
1/2 teaspoon salt
3/4 cup freeze-dried strawberries (plus 1/4 cup for decorating, optionally!) = 15g
1 teaspoon vanilla
1-2 tablespoons whole milk (full fat)
Instructions
To bake the strawberry cake:
In a mixer, beat the butter and sugar at medium speed until light and creamy, about 3 minutes.
Add eggs one at a time, mixing on medium speed for 30 seconds after each one, before adding the next. Scrape down to the bottom of the mixing bowl with a spatula to make sure all of the butter and sugar are mixed in.
Whisk together the flour, baking powder and salt. Add a third of the flour mixture to the mixer and mix on low speed only until incorporated.
In a blender or food processor, blend fresh/frozen and freeze-dried strawberries until smooth.
Whisk together milk, strawberries and vanilla. Add half of the strawberry mixture to the mixer and mix at low speed only until incorporated. Mix in another third of the flour, then the rest of the strawberry mixture, and then the final third of the flour mixture.
Divide the batter between three greased 8” pans. Tap the pans on the counter to level the batter and then bake at 350C or 175C for 23 minutes. When the cake springs back up when you poke it, the cakes are baked. Don’t bake any longer than this or the cakes will dry out.
Let the cakes sit in the pans for 5 minutes to cool slightly and then turn over onto a wire rack and leave them to cool.
To make the strawberry buttercream filling and frosting:
Mix butter and sugar together at low speed for 4 minutes, until smooth.
Blend freeze-dried strawberry in a blender or food processor to make a powder. Mix the powder into the buttercream.
Add milk 1 tablespoon at a time until the buttercream is the consistency of peanut butter or stuff whipped cream.
To layer and frost the cake:
Spread a bit of buttercream onto the middle of a cake board or flat plate or platter. Press the first cake layer onto the buttercream to secure it in place.
Spread strawberry buttercream to cover the top of the cake layer and then place the next cake layer on top. Spread strawberry filling on top and then add the final cake layer.
Spread strawberry buttercream to cover the cake. Smooth with a cake comb or offset spatula. To add texture, drag a spoon in arc motions, pushing it gently into the frosting to make swirls.
Serve this cake at room temperature. You can refrigerate it for 2 days but take it out of the fridge at least 2 hours before serving.
Notes
You can use salted butter instead of unsalted butter - just leave out the salt in the recipe.
How to make white buttercream frosting is one of the most commonly asked questions about cake decorating so in this tutorial I'll share four hacks to help you say goodbye to yellow buttercream!
#1 Beat the butter
The first hack for white buttercream frosting is also the very first step of making it. I'm using my 4 Minute Buttercream recipe in this tutorial and I use it for all of my cakes.
Beat the butter first, all on its own for a few minutes at medium speed. You want it to be completely smooth and move easily around in the mixing bowl. This only happens if butter is at room temperature so take it out of the fridge about 4 hours before.
Now add the icing sugar or powdered sugar, which will lighten the butter a lot more. Continue with the recipe and your buttercream will be whiter than if you hadn't beaten the butter alone. Look at how much lighter the buttercream is after beating it for five minutes, compared to one minute:
#2 Add violet to make white buttercream frosting
If the buttercream is still yellow, add a tiny bit of violet. This has to be violet - purple won't work because it's the blue tint of violet that offsets the yellow. Dip a toothpick into the bottle to get a tiny amount because a full drop will be too much. Check out this tutorial for more ways to use toothpicks for cake decorating!
Drag the toothpick through the buttercream to leave a streak behind.
Mix it in and look at the difference before and after adding violet:
You could add white colouring or white icing color but you'll need a lot for a full batch of buttercream. There are two negative side effects: an unpleasant flavour and it will make the buttercream very runny.
#3 Choose your background
This third hack for white buttercream actually has nothing to do with the buttercream itself. You only notice off-white isn't bright white when it's next to something that is bright white. So after making a cake, choose your background wisely. Opt for colourful decorations and don't display the cake in front of a white background either. Look how different this white buttercream frosting looks when the background is white compared to colourful. The cake looks whiter when the background isn't white.
#4 Use shortening for white buttercream frosting
If none of these hacks make your cakes look white enough, the final hack is to tweak your buttercream recipe. As you saw at the beginning, the butter in buttercream is yellow and gives buttercream that yellow tint. You can replace the buttercream with a vegetable shortening like Trex or Crisco.
These are white, not yellow, so your buttercream will be bright white. Think of the cakes you can buy from a grocery store or supermarket - those are made with shortening instead of butter.
The flavour will be different without butter so with this substitution, you're sacrificing that. An alternative is to substitute half of the butter with shortening. This will make the colour whiter but you'll keep the delicious buttery flavour. An added benefit of using all or half shortening is that the buttercream will be more stable. This is a great option in hot climates when the cake will be served outside.

Layer your cake and fillings, cover everything in buttercream or any other frosting, add some decorations and tadaa! With the right tips and tricks it really can be this easy and in this tutorial I'll show you how to decorate a cake!
How to assemble a cake
Maybe the most important part is to pipe or spread a bit of buttercream onto the middle of your cake board. This will attach the cake so it doesn't slip and slide around while you frost and decorate it. Push your first layer of cake down onto this and it will will act like glue to hold it still. I'm using my Perfect Chocolate Cake and my 4 Minute Buttercream for this tutorial.
Now alternate between your cake layers and your filling. You can divide your cake layers in half to make twice as many layers, which means more filling in between. Your filling can be buttercream or you can use jam or lemon curd or Nutella or anything else you like. Filling adds flavour but it has two other purposes as well. It helps to level the cake so that it's flat for every layer you put on top. It also acts as glue to hold the next cake layer in place so that the cake is straight.
You can pipe the filling on using a piping bag or you can spread it on. Using a piping bag is quicker and neater but both work.
How to crumb coat a cake
After you've assembled your cake it's time for the crumb coat. This is the first layer of frosting you're going to put onto your cake. Spread (or pipe and then spread) this all over the top of the cake and around the sides. The purpose of the crumb coat is to trap any crumbs that come off the cake so they get stuck in this layer of frosting. This means they won't go into the final layer of frosting, so you won't have visible crumbs on your cake.
Because this is going to be covered up with another layer of frosting, this doesn't need to be really neat. It does need to cover up all of the naked cake so those crumbs can't get into the final layer of frosting.
When you've finished your crumb coat, put the cake into the fridge or the freezer to chill it. It will need about 15 minutes in the freezer 30 minutes in the fridge. When the crumb coat gets cold it will set, which is necessary before the next step.
How to frost a cake
After chilling the crumb coat, your final layer of frosting will sit on top instead of blending together with it. This is what keeps the crumbs out of the final layer of frosting.
Spread your frosting all over the top and sides of your cake and then switch to a straight cake comb. This is the first reason for using a cake board: it provides a flat surface to rest your cake comb. Now you can line the comb up straight to create straight sides as you scrape around the cake. So push the base of your cake comb down on the cake board as you spin the turntable. Press very gently against the cake to scrape off the outer layer of frosting. If you press too hard you'll cause the buttercream to tear and create air bubbles. You might also take off too much frosting and expose the crumb coat underneath.
After scraping around the cake a few times, spread more frosting over any indents or air pockets and scrape again.
When the frosting is smooth, tidy up the top edge by pushing sideways with your offset spatula. Make sure you don't push down because that will cause bulges around the sides of the cake.
How to decorate a cake
How to decorate a cake with sprinkles
The best time to add sprinkles to the cake is now, while the frosting is still soft and sticky. Lift your cake up and put it onto a tray, which will catch any falling sprinkles. This is the second reason for using a cake board: it makes it easy to move the cake around while you're decorating it or to transport or serve.
I like to pick the big sprinkles out of a sprinkle mix and only push the smaller ones into the side of the cake. Press them into the bottom inch or so of the frosting. Then at the end, hand place the biggest sprinkles so that they're evenly spread around the cake.
When you finish, tap the cake board a few times so that the extra sprinkles fall off onto the tray. You can do this is because you've chilled the cake so it's set onto that dot of buttercream on the cake board. You don't need to worry about the cake falling over! Tilt the tray so that the sprinkles roll down to the bottom corner and then pour them back into the container.
How to decorate a cake with piped swirls
Before piping onto the top of the cake I really recommend chilling the cake briefly to set the frosting. 15 minutes in the freezer or 30 minutes in the fridge is enough time. While it's chilling, scoop up your leftover frosting and put it into a piping bag fitted with any star-shaped tip. I'm using a 1M tip.
Take your cake out and that short amount of time in the fridge or freezer will have firmed up the frosting. Now the weight of the swirls you pipe on top won't cause the frosting to sink or droop.
You can pipe very tall swirls, like the ones you would pipe onto a cupcake, or just pipe a few rings. I'm piping two laps around for each of my swirls. Always pull away in the same direction so that the swirls look neat at the end.
Add a few more sprinkles on top while the piping is still soft and sticky so that they attach easily. I recommend storing cakes in the fridge so that the frosting and decorations don't droop or slide off the cake.
How to serve a cake
Take the cake out of the fridge 2 to 4 hours before you serve the cake. This allows the cake and buttercream to warm up to room temperature and that's when they will taste the best!

Turn any image into an eye-catching, edible mosaic cake with this simple but stunning technique! Use basic tools and materials like parchment paper or wax paper, a toothpick, and coloured buttercream.
Assemble a layer cake
Alternate cake layers and filling to assemble a layer cake. The taller the cake, the more space you'll have for your mosaic cake design. Check that each layer is lined up directly on top of the layer below so that your cake is straight. If the sides lean even slightly, it will be impossible to wrap the mosaic tightly around the cake.
Cover the cake in a crumb coat, which is a thin layer of frosting to trap any crumbs. Normally this doesn't need to be neat but for this design it's important it's smooth. The mosaic design is going to sit on top, mimicking this shape of the cake.
Measure the cake and your mosaic cake design
Now measure the height of the cake so that you know how tall to make the design. To measure the circumference, wrap string around the cake or just multiply the width by 3.14 to calculate the circumference. Cut a piece of parchment or wax paper about a finger taller and two fingers wider than the circumference.
Draw a mosaic cake design
Chill the cake in the fridge while you draw your design. I'm folding my paper in half twice so that I have four sections for four different flowers.
Use a thick pen or marker to draw because it makes wide gaps in between each petal. This way, each petal will become a separate tile when you transfer the image to create a mosaic cake.
Transfer your design onto paper or acetate
You can create your design on parchment paper or wax paper by adding buttercream to the other side, but acetate is thicker and stronger so if you have it, that's ideal.
Notice that if your parchment or acetate comes in a roll it will curve. Put your design on the inner side of the curve so that it's curling up from the table or countertop. Tape down the corners or use some objects to weigh it down.
Tint buttercream whatever colours you choose. To make a few shades of each colour, mix the colour and divide it between a few bowls or holes in a muffin pan. Then add different amounts of plain white buttercream to each.
Next, you'll trace the image you drew to turn the drawing into a mosaic of buttercream tiles. There are lots of ways to create the tiles for the mosaic design, both with and without piping bags.
Pipe a mosaic cake design using piping bags and several piping tips
If you have several piping bags and small round piping tips, use a different one for each colour. Switch between the colours to pipe your design by squeezing the buttercream out to trace over the design you drew earlier. The smaller the piping tip, the easier it is to pipe little details.
Make points at the tips of petals with a toothpick, nudging the buttercream to reshape it while it's still soft, before it sets. The consistency of your buttercream is really important for this. If it's too stiff it will take a long time to pipe all of the mosaic tiles of a design. You'll have to squeeze the bag hard to push the buttercream out, which is tiring and will cause cramping. The best consistency for buttercream is runnier, slightly thicker than whipped cream. You'll be able to squeeze it easily out of the piping bag and it will fill your outlines easily. I'm using my 4 Minute Buttercream for this mosaic cake.
Use piping bags with only one piping tip without couplers
If you only have one small round piping tip, you can use it with several piping bags. Put your coloured buttercream into piping bags with no piping tips, just the ends of the bags cut off.
Then put the piping tip into another piping bag. Now drop one of the coloured bags into the bag with the piping tip.
When you squeeze the bag you'll push the buttercream out through the piping tip. And when you finish with this colour it's easy to switch to a different colour. Just pull this coloured bag out of the bag with the piping tip and drop the next coloured bag in.
Squeeze the bag to get the last little bit of the previous colour out, piping it into a bowl. When you see the new colour coming through, it's ready to pipe!
Start with the outline of each petal or shape and then fill it in with zig zags. Make sure you don't pipe over the lines you drew because you need those gaps to stay there. The gaps keep the tiles spaced apart from each other, which will turn the piping into a mosaic.
Pipe all of the details you want to be this colour. Then pull this colour out and drop the next colour in. Squeeze until you see the new colour coming through and then pipe with this colour.
Use piping bags with couplers
If you have couplers it will be even easier to switch between colours. After putting a coupler into each piping bag, put your piping tip onto the outside of one of the bags. Screw it onto the coupler using hte coupler ring, to hold it in place. Then fill the piping bags with different colours of buttercream. Pipe with the first colour and when you finish, unscrew the coupler ring and take the piping tip off. Put it onto one of the other couplers and pipe with that colour next.
Pipe a mosaic cake design
The more colours you use, the more interesting the mosaic cake design will be. But of course, more colours also makes it more time consuming to create your design. Aim for an equal thickness of the buttercream all over your design for the smoothest finish later. To layer colours over each other, let the first colour set first by putting the acetate into the freezer for about 5 minutes. Then add your next colour on top. This way the second colour won't blend with the first colour, it will sit on top of it.
This side you can see here isn't going to be visible because it will be pressed against the cake.
It's common for air to get trapped in between this buttercream you're piping and the acetate or parchment below it. As you fill in sections of colour by zigzagging back and forth within an outline, squeeze quite hard to push the buttercream down. Then use a toothpick to flatten it, using dabbing motions to press the buttercream into any air bubbles.
Use piping bags with couplers
If you don't have piping bags or piping tips, use sandwich bags like Ziploc bags instead. Spoon buttercream in and push it down to one of the bottom corners. Cut a tiny piece off the corner to make a hole to pipe through. You have less control over the buttercream you pipe through a soft plastic hole compared to a hard metal piping tip so your lines won't be as neat but you can tidy them up with a toothpick. Sandwich bags are really ideal I think for the next step, which is to fill in the background.
Pipe the background of the mosaic
For the background the goal is simply to fill in the remaining area with tiles. The exact size and shape of the tiles doesn't matter like it did with the flowers I piped first. That's why sandwich bags are perfect for this step. These slightly blobby shapes are fine and the sharper angles or narrow points aren't necessary like they were for the petals.
The more random these shapes are, the better. Using several shades or colours will make the background more interesting than using the same colour for all of the tiles.
Create a mosaic on top of the cake
When you've covered the acetate or parchment with tiles, pick it up and put it into the freezer for 15 minutes. This will set the buttercream so it gets very cold and firm. Meanwhile, pipe a design onto the top of your cake or just cover it with the background color tiles. Use the same technique of piping individual shapes with gaps in between them.
I'm free-handing these tiles because there's no set design for them. For another flower or specific design you might choose to sketch out your design first. Use a toothpick to scratch the shapes into the frosting on the cake, which you can then trace with buttercream.
Put the cake in the freezer for 15 minutes to set these tiles. Meanwhile, prepare a colour to fill in the gaps between the tiles, which would be grout on an actual mosaic. Grey or a sandy colour are the most common for mosaics but you could use chocolate buttercream for brown. You can use the leftovers of your other colours to make this colour but save a bit of every colour for touch-ups later.
When the tiles on the cake have set, pipe or spread this colour on top, covering up the tiles. Don't try to smooth this yet because you'll knock off pieces of the frozen tiles into the gaps.
Put the cake back in the freezer for 15 minutes to set the buttercream grout. Then use a warm metal cake comb to scrape the top flat. I'm using a blow torch to heat the straight edge of the comb but you could use hot water instead. Scrape off the excess buttercream revealing the smooth, colourful tiles underneath and creating a flat, level, sharp edge around the top of the cake.
Add buttercream grout between mosaic tiles
Now take the design out of the freezer and spread that same colour, grey for me, over the whole design. Push this colour into the gaps between the piping to fill them in like the grout in between mosaic tiles. Also spread it over the whole design because since it's been in the freezer it's not sticky anymore. This final colour of buttercream will act as glue to attach the tiles to your cake. Spread back and forth with an offset spatula or a cake comb to flatten and smooth the frosting.
Wrap the mosaic cake design around the cake
Straight away, lift up the acetate or paper and wrap it around your cake. By piping onto the inner side of the curve it will wrap easily around the cake, doing most of the work for you.
Rest the bottom of the design on the cake board so there are no gaps down there. Press the design tightly around the cake so it doesn't buckle or crease or warp, especially if you're using parchment paper instead of acetate since it's thinner and not as strong.
Press gently against the cake to attach the design and to flatten and smooth it. The join of the beginning and the end of the acetate or parchment should overlap slightly. Now put the cake in the fridge for at least an hour or the freezer for 30 minutes.
Unwrap the acetate or paper and do touch-ups
Pinch a corner of the acetate or parchment and peel it off to reveal this eye-catching mosaic cake design.
To level the top edge, use the edge of the blade of your offset spatula or a sharp knife. Slice around the cake, taking off the excess buttercream to tidy up any imperfections.
Hold your metal cake comb under hot water or run a blowtorch along the edge to heat it. Then scrape around the cake a few times to smooth any bumps or imperfections in the frosting. The hot metal will melt the outer layer of frosting and drag it around the cake, filling in tiny air bubbles. Air bubbles happen when the buttercream you pipe doesn't go all the way down to the acetate or parchment paper because there's air trapped down there.
Pipe or spread coloured buttercream into any deep air bubbles to fill them in. Then scrape over that part of the cake to take off the excess buttercream and leave a flat surface behind.
The result of this mosaic cake technique is a very elaborate design that only uses basic tools and materials. From start to finish this cake took 2 hours to assemble, frost and decorate.

Let's start with buttercream consistency. I like to use gel colours because they're more concentrated than liquid colours so they won't make the buttercream watery. As you mix the colours in you'll notice a lot about the consistency. It's too stiff if it's difficult to stir and it tears as you stir, breaking apart from itself and creating air pockets. You'll see lots of little lines of texture within the buttercream if it's thick and stiff. This buttercream is too stiff:
You can thin out buttercream by adding milk just a spoonful at a time. The other option is to scoop out a third of the buttercream and put it into a microwave safe bowl . Then microwave this for just 10 seconds. It's going to be very runny and melted and when you pour that into your buttercream it will thin out the thick stiff buttercream. The two consistencies will mix together to make a silky smooth buttercream, perfect for frosting a cake. Stirring it will also knock out any air bubbles in the buttercream. Can you see how much smoother this is than it was before?
The technique for how to frost a cake
Even with the perfect consistency, you won't get smooth frosting without the right technique. For this you'll need an offset spatula and also a cake comb. I like to use both a plastic and a metal comb and I'll show you why later.
Start by spooning some buttercream onto the top of your cake. The crumb coat should have set while chilling in the fridge for at least 30 minutes first. Spread the frosting to cover the top of the cake and you want it to stick out over the sides as well. That will help you get really nice sharp angles later. Hold your offset spatula at a 45° angle and spin the cake to flatten the frosting on top.
Then whisk the spatula away and scoop up more buttercream and spread it onto the side of the cake. I like to start at the top of the sides, spreading from side to side. At this point you're just covering the whole cake so that you can't see the crumb coat anywhere. Don't worry about how smooth this frosting is yet. However, you're aiming for an even thickness so if the frosting seems thinner in some parts, add more there now.
If your frosting is the right consistency it will transfer easily from your spatula onto the crumb coat. Your spatula will glide over it as you spread it, leaving a smooth surface behind. You won't see lots of tears or air bubbles or texture.
Go all the way to the bottom of the cake, covering up the crumb coat down to the cake board. Once it's all covered up, check the evenness of this frosting. On my cake the frosting looks thicker at the bottom so I'm spreading more around the top of the cake.
Push diagonally upwards to make the frosting stick up above the top edge of the cake. This lip or wall is important so that you can get sharp angles from the sides to the top later.
Now switch to your cake comb. Reach as far around as you can with your left hand for a really long spin on your turntable. Hold your cake comb on the cake board, pressing down to line it up straight. Push it slowly against the cake and then spin the cake on its turntable. You'll be able to scrape all the way around the cake because you reached so far around the turntable. Swipe away and then scrape this buttercream back into your bowl. There should be no crumbs in it because you've let the crumb coat set so you can reuse this buttercream for touch-ups later.
After scraping around the cake two or three times with your cake comb, you'll see where the frosting is thinner. Spread more frosting over those parts and any little indents, too. Scrape around the cake again to take off the excess and leave a smooth surface behind. Do these touch-ups as many times as you need to, spreading on more frosting to fill in any shallow areas and then scraping around the cake to smooth the frosting.
Now let me show you why I like to use a metal cake comb as well as this plastic one. The plastic comb is quick to use and I like the lightweight feel and flexibility. But it gets dinged along the edge easily by knocking or dropping it and those bumps drag along the frosting and leave trails behind.
If you're wondering how to frost a cake with a metal cake comb, here are the details. After getting the frosting fairly smooth, heat the edge of a metal cake comb. You can do this by running it under hot water or dipping it into a bowl or tray of hot water. The method I like best is to use a torch to heat it!
The edge of a metal cake comb doesn't get damaged as easily as plastic, so you'll get smoother frosting with it. By heating it, as you scrape around the cake it melts the very outer layer of frosting and drags it around the cake to fill in any imperfections. This leaves a super smooth surface on the frosting.
How to frost a cake with sharp edges
When the sides are smooth, it's time to tidy up the top edge, where the frosting sticks up above the cake. I use a long offset spatula for this. It needs to be clean so wipe any buttercream off it before you use it. To tidy up the top edge it's really important to push sideways. Don't push down at all or you'll create a bulge in the sides of the frosting around the cake. Push this buttercream across the top of the cake and lift it off on your spatula. Scrape it back into your bowl and wipe the spatula clean on a towel or paper towel. You don't want any frosting on the blade. Then spin the cake to do the same for the next section of the cake.
Look what happens if you don't spread your frosting high enough. There are gaps in the frosting where it's thinner or shallower, which will become indents in the top edge. Spread more buttercream onto the indents on top and on the side of the cake and then scrape around the cake again with your cake comb. You'll smooth this touchup frosting so that the sides are straight. Swipe sideways with your offset spatula to flatten and smooth it on top of the cake, too.
When you finish, go around the cake again and swipe wherever the frosting is higher. This will make the top edge straight and level all the way around the cake.
Summary of how to frost a cake
For super smooth frosting on a cake there are three tricks. First, the cake needs to be assembled, crumb coated and chilled correctly. I showed how to do those steps in the previous two tutorial in this series: how to make layer cakes and how to crumb coat a cake. Second, the buttercream needs to be the perfect consistency and third, you need to have the right technique.
