Chocolate Chip Cupcakes with Dark Chocolate Frosting

Chocolate cupcakes with chocolate chips and chocolate frosting. Yeah, you need a high chocolate tolerance for these. I made the cupcakes with Niki and the frosting with Arik.
The plain "before" cupcake:
Here's the cupcake recipe. Tip: we put in a whole 2 cup bag of chocolate chips. Do it.
After frosting:
We sort of made up the frosting by taste as we went along. Arik assured me that nothing would go wrong if we just kept mixing in different delicious ingredients and taste-testing the results. I was skeptical but he turned out to be right-- the chocolate frosting is really rich and delicious.

Start by melting the chocolate in a bowl over simmering water, and slowly add butter, cream, sugar, and cocoa powder. Keep stirring until it thickens and let it sit in the fridge until it has frosting consistency.

Ingredients
1/2 stick butter
3 squares unsweetened baker's chocolate
1 cup heavy whipping cream
1 1/2 cup confectioners sugar
2 tablespoons cocoa powder
Just one was enough to put me into a blissful chocolate coma.
