In this tutorial I'm going to show you how to decorate this cheerful rainbow striped cake with a rainbow drip
0:05
You'll need small amounts of buttercream of all of the colors you're going to use for your cake
0:09
and I'm using nine rainbow shades for mine. This is my four-minute buttercream and the recipe and tutorial link is in the video description
0:17
Cover your cake with a crumb coat of frosting to trap in any crumbs that might come off the cake
0:21
and then let the crumb coat set. I put mine in the fridge for 30 minutes
0:26
Press a striped cake comb against the side of the cake in a few places. to imprint the grooves of the comb, so you know where the stripes will eventually be on the cake
0:36
Each little line indented in the cake will be a different coloured stripe at the end
0:40
Use these imprinted lines as a guide to spread your colours of buttercream around the cake
0:45
making sure you have a different colour going over each of the lines
0:49
You could pipe the buttercream on instead of spreading it, but since I have nine colours, I'd need nine piping bags
0:55
and that's a lot of washing up to do afterwards, so I'm using my offset spatula to spread the colours on instead
0:59
the colours on instead. You don't have to be really precise about where each of the colours
1:03
go because we're going for more of a rainbow ombre effect, so it's fine if they blend together
1:07
gradually between the stripes. When you've covered the whole cake in bands of coloured buttercream
1:12
smooth the frosting by scraping around the cake a few times with a frosting smoother
1:16
and wherever there are air pockets in the frosting, spread on some more buttercream of that colour
1:21
to fill in the gap. Scrape around the cake again to smooth the frosting, and when the frosting is
1:26
not perfect but fairly smooth, switch to your striped cake comb. Rest the base of the cake comb
1:32
on the cake board and press it gently against the side of the cake and then spin the turntable
1:37
to scrape all the way around the cake leaving stripe grooves in the rainbow frosting on the cake Scrape any buttercream off your cake comb into an empty bowl and save it for later and then scrape again and again until the stripe grooves are clear and smooth If there are air pockets in the stripes fill them in by spreading
1:54
on some more buttercream of that colour, and then going around again with your striped cake comb

2:10
is and after chilling the cake you can cut it all off with a sharp knife. Put the cake in
2:15
the fridge for 30 minutes or in the freezer for 15 minutes to set the stripe grooves. Meanwhile
2:21
fit a piping bag with a star-shaped tip, like this 1M tip. Now we're going to use up the rainbow
2:27
buttercream you scraped off the cake with your frosting smoother and striped cake comb
2:31
I'm filling half of my piping bag with plain white buttercream and then the other half
2:35
with the blended rainbow buttercream, but you can use only the rainbow buttercream if you like
2:40
Set this aside for some finishing touches at the end. When the frosting on the cake is chilled and firm
2:46
take the cake out of the fridge and spread white butter cream all over the cake
2:50
to fill in the stripe grooves. You'll spread it all over the rainbow stripes too, but that's fine
2:55
We'll tidy everything up in a minute. If you're looking for variations on stripe designs

check out my tutorial on four secrets for perfect stripes on cakes, and I've put the link for that in the description below this video
3:06
As you're filling in the stripe grooves, spread quite firmly to push the buttercream
3:10
all the way into the grooves so there aren't any air pockets. Cover the top of the cake as well, and now it's time to reveal the rainbow stripes
3:18
Scrape around the cake with your frosting smoother, which will start to smooth the frosting and take off some of the excess white buttercream
3:25
Keep scraping again and again which will take off a little bit more buttercream with each scrape The rainbow stripes will be very subtle to start with as they begin to show through the frosting and they have lots of white patches within them
3:38
But with each scrape, they'll get clearer and neater. If you pressed your striped cake comb into the crumb coat before you started
3:45
and used those indents to guide where you spread or piped the coloured buttercream
3:49
you'll end up with a different colour for each stripe, but the colours will fade through each other like a rainbow, blending together nicely
3:55
Tidy up the top edge and if you want to give the cake a sprinkled border around the bottom
3:59
it's easiest to do this now before the frosting sets completely. Place the cake on a baking tray or hold it above a large cake pan and pick up handfuls of
4:08
sprinkles pressing them into the bottom inch or so of the cake
4:12
The white frosting will be sticky because it's still fresh and soft, but the coloured butter cream has been chilled so it won't be sticky anymore and you'll have to
4:19
press quite firmly for the sprinkles to stick to it. Now put the cake back in the fridge to set the frosting again
4:25
For the drip, you can use candy melts or white chocolate. If you're using candy melts, place a few colored candy melts in each bowl
4:31
combining colors to make any shades you don't have, like pink and blue to make purple
4:36
Now you can either warm heavy whipping cream or double cream until bubbles form around the edges
4:42
and then pour the cream into each bowl, or spoon cold cream into the bowls and put them in the
4:47
microwave one by one. For drips made with candy melts, you need four times the candy melts
4:52
compared to cream. So for example 40 grams of candy melts and 10 grams of cream. After melting
4:58
the drips and letting them come to room temperature, do a test drip on the side of the bowl before
5:03
you move on to your cake. If you're using white chocolate instead of candy melts
5:08
melt three parts of white chocolate with one part of cream for example 300 grams of chocolate with 100 grams of cream and then divide the drip between bowls and add a tiny bit of gel color on a toothpick to each bowl Take your cake out of the fridge and apply the drips with a spoon
5:23
scooping up some of the drip and then holding your spoon above the outer edge of the cake
5:28
and angling it to prepare the drip spill out slowly, moving your spoon around the edge of the cake and pausing wherever you want there to be a drip
5:36
Your cake needs to be cold for this because the coldness of the cake stops the drip from running all the way down
5:40
all the way down to the bottom of the cake. If you do find that your drip is too runny even when it's at room temperature, you can add
5:47
a little bit more chocolate or candy melts to make it thicker
5:51
Change colours as you work your way around the cake, and ideally all of your drips will be made
5:55
with the same ratio of cream to chocolate or candy melts, so they'll all be the same consistency
5:59
and you'll get the same drip effect but in lots of different colors
6:03
Don't worry about how neat the edge of the drip is around the edge of the top of the cake
6:07
because you're going to cover that up in a moment. When you finish the drip, pick up your piping bag with the leftover rainbow buttercream inside
6:14
and pipe swells or ruffles around the top of the cake. To pipe these ruffles, I'm wiggling my bag back and forth so that the buttercream folds over itself
6:24
Because I filled one side of the bag with white butter cream and the other half with rainbow butter cream
6:29
the ruffles are white on one side and rainbow on the other side
6:33
Hold your bag in the same position as you work your way around the cake so that the colors
6:36
line themselves up the same way for each ruffle. I'm scattering a few sprinkles on top of the cake and pressing a few into the sides in random places
6:44
Or if you have any smudges on your stripes, you can be strategic about where you place the stars so that you cover those up. Tadda
