I tried this on a chocolate cake I made recently. It is excellent. The recipe came from Allrecipes.com. I added some extra cocoa and about two TB strong coffee. I also used neufchatel cream cheese.

Chocolate Cheese Frosting

1 (8 ounce) package cream cheese, softened

4 tablespoons milk

4 cups confectioners' sugar

1/4 cup butter, softened

2 teaspoons vanilla extract

1/2 cup unsweetened cocoa powder

1/2 teaspoon ground cinnamon

In a bowl, beat together the cream cheese, 3 tablespoons milk, confectioner's sugar, butter, vanilla, cocoa, and cinnamon to a spreadable consistency. Beat in additional milk if necessary. For a darker frosting add more cocoa or up to 4 ounces melted chocolate. Spread onto cooled cake.
