How-To: Inverted Chocolate & Vanilla Cupcakes

These cupcakes can be quite tedious, but they are always a hit whenever I make them. These are chocolate cupcakes with a vanilla frosting and a chocolate topper and a vanilla cupcake with chocolate frosting and a vanilla topper. I find that most people like the mixture of the two flavors, but you could always customize and make whatever combination best suits you and your guests. Please do not be alarmed by the number of steps in the recipe. It looks like a lot, but it does not take as much time as one might think, and from my own experience I definitely think that following all of the steps are well worth the results.
