If anybody has made this cake and has suggestions for my next attempt, I would love to hear them!
The cupcakes around the cake are actually just chocolate chip cookie dough just baked in cupcake cups. I had made the dough the day before and wrapped in in clear wrap. It was just sitting in the fridge, so I decided to give it a try. I put a scant golf ball-sized glob of dough in each and baked at 325 for about 20 min. The were really good! I just globbed a bit of the blue buttercream on top so it would match. They were really easy and a good alternative to cupcakes/cookies that I will do again.
