This recipe is tangy! I love it, it is especially good on a chocolate cake with raspberry sauce.
1 Cup semisweet chocolate chips
4 Tablespoons butter
1/2 cup sour cream
1 teaspoon vanilla extract
1/4 teaspoon salt
3 cups powdered sugar
Melt chocolate and butter together. Let cool and blend in the sour cream, vanilla and salt. Gradually add the powdered sugar and mix well.
