Which Came First? The Cupcake Or The Egg?

This cupcake came about from a bit of brainstorming with co-workers and also a bit of a dare. I was taking suggestions on what could be baked into a cupcake and this is the result. The Cadbury Creme Egg Cupcake. Vanilla Cake with a creme egg baked inside, topped with Chocolate Buttercream and decorated with an icing "egg."

This is what it looks like inside.
