Black Bottom Cupcakes

This is an old stand by for me. Love this cupcake with the cream cheese middle as it packs easily for lunches and doesn't make the mess that icing does. And so yummy! I've tried a few different recipes for these cupcakes and wasn't having much luck until I found this recipe. Perfect.
