This wasn't going to be just any rainbow cake though, oh no, the girls and I decided that we'd like to have a rainbow surprise inside too consisting of lots and lots of Skittles and M&Ms mmmm.
Making the sponges was the easiest part. I used a simple victoria sponge recipe :
* 200g caster sugar
* 200g butter
* 200g self raising flour
* 4 eggs
* 1tsp baking powder
* 2 tbsp milk
I multiplied the quantites by three and then divided the mixture into 6 bowls ready to create all the colours of the rainbow.
Then it was time to add the colouring to each of the bowls. I really wanted bright colours but I couldn't be sure how they would turn out when baked.
All cakes were baked for around 20 minutes however 4 of the 6 cakes were baked in a savarin cake tin to create the hole we needed in the middle.
After leaving all of the cakes to cool I then had to stick each layer of cake together, to do this I used a simple butter icing.
* 100g butter
* 140g icing
* tsp vanilla essence
Then of course the sweets needed to be added.
The next step was where I wasn't sure what to do, I became uncertain on just how to decorate the outside of the cake. I knew rolled out icing would work however whenever I've attempted in the past the icing seems to just fall apart. In the end I opted to cover the cake in candy melts and pink icing. Adding a crumb catching layer of butter cream first.
