This is the first I've heard of a mother doing Mickey Mouse for the nursery. I think it's a cute idea! I was excited when I got the cake order-I immediately knew I wanted to do the MM ears. The cake flavor is yellow cake with ganache. I get really nervous when I get an order for yellow cake because I have yet to find a recipe to my satisfaction. Flavor-wise is no issue. It's the texture I can't get right but I think that's yellow cake. I've tried at least 2 or more dozen recipes and even tried tweaking my own. I found a great white cake recipe but the yellow is still up in the air. Grrrr. If anyone knows a good one, let me know.
