Ingredients

  • 1 cup creamy peanut butter
  • 3 tablespoons butter
  • 2/3 cup powdered sugar
  • 1 teaspoon vanilla extract

Instructions

  • Place peanut butter and butter in a bowl.
  • Beat with an electric mixer until smooth.
  • Sift powdered sugar making sure to remove any lumps.
  • Add powdered sugar and vanilla extract to the peanut butter mixture.

Recipe Tips

The key to success is using regular commercial peanut butter rather than natural varieties. Natural peanut butters with separated oils create unstable frosting that won't set properly. Room temperature butter is crucial for smooth mixing.
