  • Total Time: 10 minutes
  • Yield: 12 servings

Ingredients

Frosting Ingredients

  • 1 cup unsalted butter, softened to room temperature
  • 2 cups powdered sugar
  • 1/3 cup creamy peanut butter
  • 1 Tablespoon whole milk

Instructions

  1. Beat the Butter: In a medium bowl, use an electric mixer to beat the softened unsalted butter for 3-4 minutes. Continue mixing until the butter lightens in color and becomes creamy, which will help create a smooth and fluffy frosting base.
  2. Add Remaining Ingredients: Add the powdered sugar, creamy peanut butter, and whole milk to the bowl. Beat all the ingredients together for another 3-4 minutes until the frosting is light, fluffy, and well combined. Be sure to scrape down the sides of the bowl as needed to incorporate all ingredients evenly.

Notes

  • Make sure the butter is softened to room temperature for easier whipping and a smoother texture.
  • If the frosting is too thick, add a little more milk, one teaspoon at a time, until you reach your desired consistency.
  • For a stronger peanut butter flavor, you can add an extra tablespoon of peanut butter.
  • This frosting is best used immediately but can be stored in the refrigerator for up to a week; re-whip before using if chilled.
  • For a dairy-free version, substitute the butter with vegan butter and use a non-dairy milk alternative.
