1 cup semi-sweet chocolate chips
1 tbsp butter
1 tsp vanilla extract
1/4 tsp salt
3 tbsp milk
1 1/4 cups sifted powdered sugar
Combine the chocolate chips and butter. Melt in the microwave until chips are melted enough to make mixture smooth when stirred. (Or cook over hot water until melted.) Remove from heat or microwave. Mix in the vanilla and add the salt. Beat in the sifted (important to eliminate lumps) powdered sugar alternately with the milk until of a spreading consistency.
