Everyone loves a rainbow 🌈 cupcake…am I right?! As an artist and customer..I love the look of a rainbow cake. But as a baker, I cringe at the thought. They’re actually a pain in the backside. We usually charge more…and if you don’t, you certainly should. They’re a faff. I internally groan when I hear that I have to make a rainbow cake. Yeah it’s the same vanilla cake recipe, but then you have to get out every bowl in the cupboard, divide the batter evenly, then use an ungodly amount of food dye to make sure the colour will still be vibrant after it’s baked. And then all the washing up. Oh, and you need to line 6 baking tins too. As I said, a faff! So it’s one thing to bake a rainbow CAKE…rainbow buttercream, slightly different, slightly easier. It’s still time consuming because… the BOWLS, and an all butter buttercream takes a lot of colour to get very vibrant, but I also used a very easy technique to get a gorgeous swirl with half the mess and all the colours.
What you’ll need:
Cling film (Saran wran)
Very large pastry bags
Rainbow Coloured Buttercream of your choice!
I actually used American buttercream for this project. Couple of reasons…it had been a very long week and I had to get 60 cupcakes iced and done before work.. (I managed to do it all in 45 minutes) Annd I also find my regular Swiss Meringue takes a little more time to for the colours to develop. I made sure I didn’t compromise on taste though. I will share my recipe with you at a future date. It’s easier to make vegan too..
but you do you! 😉 x
Lay down a large strip of cling film. Make sure it’s not too much longer than your piping bag.
Spoon your buttercream into long lines in the centre of the cling film. I went in order of the colours of the rainbow…but you really don’t need to do this.
Bring one side of the cling film over to the middle, then bring over the other side. It’s kinda like making sushi! Then take the ends and give it a twirl, almost as if you’re playing jump rope.
Cut one end of the cling film bag and insert it in to your prepared piping bag that has the 1B tip in it.
Then swirl away! It’s super easy, super fun, and you avoid all the mess that you’d have if you were to line the piping bag with each individual colour.
