Ingredients
  

  • 2⅔ cups powdered sugar or icing sugar
  • ¾ cup unsalted butter softened at room temperature
  • ¼ cup peanut butter smooth peanut butter

Instructions
 

  • Begin by beating the peanut butter and butter together in a stand mixer or large bowl.
  • Then, add the powdered sugar by sifting this into the bowl. This can be done in two additions, beating lightly between each. Continue beating on a low setting until the buttercream frosting is smooth (see note).

Notes

Your goal is not to whip the frosting as adding too much air can make it more difficult to spread (creating air pockets).
If you need to adjust the consistency, this can be easily done by adding more powdered sugar or adding a splash of milk. Adding powdered sugar will thicken the frosting and adding milk will thin it. Any additions should be done a small amount at a time and checking the consistency to avoid over adding excess ingredients.
