This chocolate cream cheese frosting might be the best chocolate thing I've ever tasted.
8 oz cream cheese, softened
4 tbs unsalted butter, softened
2 cups powdered sugar, sifted
1/4 cup cocoa powder, sifted
Cream the butter and cream cheese together with a mixer and gradually add the sugar and cocoa. Try not to eat the whole bowl with a spoon. This will frost a 13 x 9 inch sheet cake or about a dozen cupcakes.
