Caramel icing

This recipe is originally from the Jumbo Caramel Banana Muffins. I thought it made a good frosting for any cake too.

• 2 tablespoons butter
• 1/4 cup packed brown sugar
• 1 tablespoon 2% milk
• 1/2 cup confectioners' sugar

 In a small saucepan, melt butter over medium heat. Stir in brown sugar and milk; bring to a boil. Cool slightly. Beat in confectioners' sugar until smooth. Transfer to a small resealable plastic bag; cut a small hole in a corner of bag and drizzle over muffins or bundt cake.
