Swirl Cupcakes

I made 5 different types of cupcakes tonight with one recipe of my favorite White Cake.

Split the recipe in half in two different bowls.
Melt 2 squares of semi-sweet chocolate and mix into one bowl of batter.

Fill one side of the muffin liner with chocolate batter and one side with white cake.  Swirl with a knife.

Mix cocoa powder into Butter Cream Frosting.
