I am thinking I will do cupcakes this year. Disney Cars cupcakes! Last year I made quite a fancy cake, a dome shaped cake that looked like Mickey Mouse. It was a three layer cake made in both round cake pans and a stainless steel mixing bowl to acheive that dome shape. The ears were cardboard, covered in foil and frosted in black.
I designed this cake myself and I think it turned out pretty well. Hint: if you plan to make black frosting, start with chocolate frosting as a base! You will use a lot of black food coloring.
