Hi! I'm going to show you how to decorate a cake with watercolour frosting with different
0:04
techniques to get a few different effects. You'll need a cake with a crumb coat. For
0:10
more information, check out my tutorial on how to build a cake
0:15
Leave your crumb coat to set for about 30 minutes in the fridge
0:19
Apply a final coat of frosting to the top of the cake and now instead of frosting the
0:23
rest of the cake, we're going to place dabs of coloured frosting all over the cake. You
0:28
can use a spatula or a spoon to spread it on, or fill a piping bag and squeeze it on
0:34
It's ok if you have small areas without frosting blobs, but the aim is to almost completely
0:38
cover the cake with frosting blobs so you don't end up with gaps where you can see the
0:42
crumb coat. For this cake I used buttercream with different amounts of melted chocolate mixed in to create different shades of brown frosting. You can
0:50
do this with food colouring instead, tinting your frosting different shades of any colour
0:55
or a variety of colours. Here I used different shades of pink frosting
1:00
When your cake is covered with frosting blobs, use a frosting scraper to smooth it all out
1:05
Pull the turntable towards you with one hand and hold the scraper against the cake at a
1:09
45 degree angle with the other hand. After you've done this once or twice, apply
1:14
more buttercream wherever you see air pockets so that as you keep smoothing, the frosting
1:19
will be the same thickness all around the cake. If you want less blending of the colours, alternate the direction you use your frosting
1:27
scraper, like this. You can touch up throughout the process whenever you see air pockets. This gives you an opportunity to play around with the colours, choosing
1:40
which colours to add to make the cake darker or lighter. When the sides are smooth, use your frosting scraper or an offset spatula to flatten the
1:57
top of the cake, pulling any frosting taller than the cake towards the middle of the top
2:02
of the surface of the cake. Here's how this cake turned out
2:10
And here's an example of what this technique looks like with coloured frosting
2:15
Now if you follow the same method with the chilled cake, you'll get a completely different
2:19
effect. Apply a final coat of frosting over your crumb coat and then chill the cake for at least an hour in the fridge
2:27
Now when you use the same technique to apply different shades of buttercream, the buttercream
2:32
sticks to the cold coat of frosting and instead of blurring together, it leaves distinct patterns
2:37
on the cake. So you're following almost the same steps as for the previous watercolour cakes, the only difference is that there's a chilled
2:44
final coat for this one. But look at the difference! I decorated this cake with buttercream succulents. Click the link to watch my tutorial on how
2:53
to make the succulents. If you want more control over how the colours
2:58
are placed on your cake, apply your final coat and chill for at least one hour and then
3:02
use an offset spatula to apply your coloured buttercream frosting. Use a frosting smoother to take off the excess frosting and spread the colour around the
3:12
cake, repeating until you're happy with the result. I added a black sprinkle border and a black chocolate drip to this cake and decorated
3:24
it with fondant cards and chips for a poker themed cake. There are so many ways to finish decorating a watercolour cake. You can add a drip or
3:33
arrange some fresh flowers on top or just leave it as it is
