This was for my MIL. It only needed to serve 7 people, but I wanted to do something a little fancy for her. Bottom cake is a 6", center is a 4 1/2" bundt (hole was filled w/chocolate marshmallow frosting), and top was an inverted cupcake. The whole thing took one cake mix, and had extra cupcakes to boot! I will definitely be making more of these- it was so fun!
