Rainbow Cake

My My Little Pony cake
I cooked the first layer and realised there was no way I had enough cake mix to make an ENTIRE rainbow - but I was content to make it a 3 colour cake instead because I don't like big big cakes and....I really didn't want to drive back to the supermarket >.> Ehe!

There's strawberry jam and whipped cream between each layer.
