my new favorite chocolate frosting

this one is creamy, super chocolaty and rich, and not too sweet, its my new favorite. i've made it twice in the last two weeks to rave reviews.

Ingredients

• 1 12-ounce package (2 cups) semisweet chocolate pieces
• 1/2 cup butter
• 1 8-ounce carton dairy sour cream
• 4 1/2 cups sifted powdered sugar (about 1 pound)

Directions

1. In a large saucepan melt chocolate and butter over low heat, stirring frequently. Cool for 5 minutes. Stir in sour cream. Gradually add powdered sugar, beating until smooth. This frosts tops and sides of two 8- or 9-inch cake layers. (Halve the recipe to frost a 13x9x2-inch cake.) Cover and store frosted cake in the refrigerator.
