Rainbow Birthday Cake

This was a birthday cake I baked for one of my besties 30th birthday earlier this year. I wanted something visually stunning and fun so make her feel like a kid again. For this recipe I cheated and used a cake kit and premade icing from my local supermarket. I just divided up the cake mix into 6 equal portions, added colouring and adjusted the cooking time so they didn't overbake. There are also many recipies on the internet . Because the cake was double the hight of the cakes I would normally bake, and so it didn't turn out wonky, I leveled each layer by trimming of the top of each sponge, which also thrilled my neices when the offcuts ended up in their triffel.
