Check out these amazing Rainbow Cakes made by the ICS students!! Not only are they cool to look at but they taste yummy too! It was also a very easy recipe to do! We used cake batter and icing gels, we simply separated the batter into six bowls and used the icing gels to make the colours of the rainbow. We then used a spoon to scoop the different colour batter into a mason jar. We put the jars in a 9×13″ brownie pan with about an inch of water and baked them for about 40 minutes at 375F.
