  • 1 1/2 cups peanut butter at room temp
  • 1/2 c butter softened, room temp

  • 2-3 Tbs heavy cream or 2% milk


  • In a medium sized mixing bowl, using hand mixer or stand mixer, cream together room temperature peanut butter and butter.
  • Add in the vanilla and powder sugar, and mix to combine.

If the frosting tastes too powdered sugary, add in more peanut butter.
