This is good. Really, really good. Try it on banana cupcakes.
1 (8 oz.) package cream cheese
3 T milk
pinch salt
2 oz. unsweetened chocolate, melted and cooled slightly
2 to 3 C confectioners' sugar
Soften cream cheese cheese in milk. Add 1 C sugar, blend well. Add another 1 C sugar, blend well. Add melted chocolate and salt. Add more sugar, if necessary, to reach frosting consistency. Beat until smooth.
This makes enough to frost a 2-layer cake, a 9 X 13" sheet cake, or 24 cupcakes. If there are any left over, eat it with a spoon. I won't tell anyone you did it.
