1/2 cup stick margarine or butter
1 cup packed brown sugar
1/4 cup milk
2 cups powdered sugar
Melt butter in saucepan. Stir in brown sugar. Heat to boiling, stirring constantly; reduce heat to low. Boil and stir 2 minutes. Stir in milk. Heat to boiling; remove from heat. Cool to lukewarm.
Gradually stir in powdered sugar. Beat until smooth and spreadable. If frosting becomes too stiff, stir in additional milk, one teaspoon at a time or heat over low heat, stirring constantly.
I especially like this frosting for homemade cinnamon rolls. This recipe will frost one jelly roll pan of cinnamon rolls.
I like to wrap individual cinnamon rolls in aluminum foil and freeze them. That way, Nate can grab one out of the freezer on his way to school or I can have a yummy snack during the day.
