This year Evan told me he wanted a rainbow cake. I made the mistake of asking him if he wanted a rainbow on the outside of the cake or on the inside, with pictures of both, which lead to him informing me that he wanted the rainbow on the inside AND the outside. Of course! :)
Evan helped mix up the colors for his cake, he helped put all the batter in the pans (all three of them!), he helped swirl the cakes, and he helped build the rainbow on the top! He did a great job.
