Fluffy Peanut Butter Frosting - cooking recipe

Ingredients

1/2 cup butter, softened
1 cup creamy peanut butter
3 cups confectioners' sugar
1 teaspoon vanilla extract
3 tablespoons milk, as needed

Preparation

Cream together butter and peanut butter until well blended and you can't see any of the butter anymore.
Add sugar, one cup at a time, mixing until well blended.
Add vanilla.
Begin adding milk, a little at a time until it reaches the consistency you want. I usually don't measure, but I think I use all 3 tablespoons.
Whip on high until fluffy and pale in color.
