Ingredients for Peanut Butter Frosting

  • Peanut Butter – Use regular peanut butter and avoid the ‘natural’ brands that tend to separate easily. Creamy or crunchy is up to the cook as either will work in this recipe!
  • Butter – Use unsalted butter in this recipe. I usually add a pinch of salt to frosting but the peanut butter will already contain a little bit.
  • Powdered Sugar – Also known as confectioners’ sugar, it is added for consistency and sweetness.
  • Milk – Milk (or heavy cream) gives this frosting just the right texture.
  • Vanilla Extract – Adds flavor.

Variations – Add a little cocoa powder for a new layer of flavor.
