Chocolate Fudge Frosting
This recipe is basically Hershey's Perfectly Chocolate Chocolate Frosting, except that the butter is room temperature rather than melted. I have had better success with it this way. I typically double this recipe when filling and frosting an 8-inch layer cake.
Chocolate Fudge Frosting
½ cup butter, room temperature
⅔ cup cocoa
3 cups powdered sugar
⅓ cup milk
1 teaspoon vanilla
Combine in a mixing bowl and beat until smooth and fluffy, several minutes.
