I have had this recipe for over 30 years. Cream may be substituted for the milk for added richness.
INGREDIENTS (for 1 servings):
- 2 tablespoons butter
- 3 tablespoons milk
- 1/2 cup packed brown sugar
- 1 cup confectioners' sugar
- 1/2 teaspoon vanilla extract
In a saucepan over medium heat, melt the butter, and mix in 3 tablespoons milk and brown sugar. Boil vigorously for 1 minute.
Remove from heat, and beat in 1/2 cup confectioners' sugar. Cool slightly, and beat in the vanilla and remaining 1/2 cup confectioners' sugar. Add more milk if the mixture is too thick.
