  • 1 cup (268g) creamy peanut butter
  • ½ cup (113g) unsalted butter softened
  • 4 cups (452g) powdered sugar
  • ¼ teaspoon salt
  • 1 teaspoon vanilla extract
  • 6 tablespoons (90ml) heavy whipping cream


  • Beat peanut butter and butter in a large bowl with a hand mixer until creamy (or in the bowl of a stand mixer fitted with the paddle attachment).
  • Mix in 1 cup of powdered sugar at a time, slowly, until mixture is crumbly. Add salt and vanilla and mix, then add 1 tablespoon of heavy whipping cream.
  • Beat frosting until smooth, adding more heavy whipping cream until you reach the desired consistency (I always add 6 tablespoons).
  • Pipe or frost as desired.
