Original Inspiration: http://offbeatfamilies.com/2011/06/rainbow-themed-baby-shower
What I Did: This was for my rainbow themed baby shower. I insisted on making my own cake, because I thought this was so cute. It seemed easy. Well I spent a few hours the night before baking all the cakes, then 15 minutes before the shower decided to start stacking them. I got to about the 3rd layer before they collapsed and fell into a mess. Luckily my husband ran out and bought a cake. This one ended up being served out of a huge bowl.
Next Time I Will: Next time I would level off the layers. The rounded tops made the stacking impossible.
