1 cup sugar
5 tablespoons butter or margarine
⅓ cup milk
1 cup chocolate chips
Combine sugar, butter and milk in a saucepan and bring to a boil, stirring constantly. Boil for 1 minute, stirring constantly. Remove from heat and add chocolate chips. Stir until chips are melted and mixture is smooth. It will be quite runny. Refrigerate until cool and of a thicker, spreading consistency. Check every 15 minutes or so and stir. If it gets too stiff, heat it briefly to make it spreadable.
