Fluffy Peanut Butter Frosting

Is even better than it looks!!! Here's the recipe:
1/2 C softened butter
1 C creamy peanut butter
3 Tbls milk, as needed
2 C confectioners sugar

Beat butter and peanut butter. Gradually mix in sugar. As it starts to thicken add milk one tablespoon at a time until the sugar is mixed in and the frosting is thick and spreadable. Beat for at least 3 minutes to get it good and fluffy. Enjoy - we did!
