I’ve always eyed rainbow cakes – I like bright things far too much – and finally decided to try making one. I modeled it off of Sweetapolita’s rainbow cake, but changed things up with the decorations, mostly based on the birthday boy’s favourites.
The cake recipe can be found here: http://sweetapolita.com/2011/04/rainbow-doodle-birthday-cake/
I didn’t have room in the fridge when I made them, but I would definitely do that next time. The cake was a bit sticky, so I had trouble getting the layers off of the various cake racks and cutting boards I stuck them on. I don’t think the kitchen was made to keep 6 separate cake layers! Using gel food colouring worked really well, as the cake kept the bright colours through baking. Also, I recently invested in a cake leveler, so I like to think my next attempt will be less lopsided!
To decorate the cake, I used a cream cheese icing and Skittles, but any bright candy will work!
- 2 8oz packages of softened cream cheese
- 1 cup (227 g) softened unsalted butter
- 2 tsp. vanilla extract
- 4 -½ cups icing sugar
- Mix together the cream cheese, butter, and vanilla until creamy.
- At a low speed, gradually add the icing sugar. Scrape sides of bowl as needed. You can adjust the icing sugar / add a little milk to get the consistency you want.
A touch lopsided, but decently rainbow like.
