1 can (12.4–oz) refrigerated cinnamon rolls, with icing
1/2 cup peanut butter
Bake cinnamon rolls as directed on package.
In medium bowl, mash banana with a fork. Stir in peanut butter and reserved icing until blended to create a peanut butter dipping sauce. If mixture is too thick, stir in water, 1 teaspoon at a time, until it reaches desired consistency. Spread on warm rolls.
