Description

This creamy Peanut Butter Frosting is a quick and delicious way to add rich, nutty flavor to your cakes or cupcakes. Made with smooth peanut butter, buttery confectioners’ sugar, and a hint of vanilla, it whips up in just minutes to a fluffy, spreadable consistency that’s perfect for any dessert.


Ingredients

Scale

Frosting Ingredients

  • 2 cups confectioners’ sugar
  • 1/2 cup butter, room temperature
  • 2 tablespoons milk
  • 1/2 cup smooth peanut butter
  • 1/2 teaspoon vanilla extract


Instructions

  1. Cream the Butter and Peanut Butter: In a large mixing bowl, beat the room temperature butter and smooth peanut butter together using a hand mixer or stand mixer until the mixture becomes smooth and creamy.
  2. Add Powdered Sugar: Gradually incorporate the confectioners’ sugar, adding it in 1/2 cup increments. Beat well after each addition to ensure it is fully combined and the frosting stays smooth.
  3. Add Milk and Vanilla: Pour in the milk and vanilla extract, then continue beating the frosting until it reaches a smooth and fluffy texture. If the frosting is too thick, add additional milk one tablespoon at a time until you achieve the desired spreading consistency.
  4. Frost Your Cake: Use the peanut butter frosting immediately to generously frost your favorite cake or cupcakes. Spread it evenly with a spatula or knife, then enjoy the creamy nutty flavor!

Notes

  • Room temperature butter ensures a smooth frosting texture.
  • If frosting is too runny, add a little more confectioners’ sugar to thicken it.
  • This frosting is best used fresh but can be stored covered in the refrigerator for up to 3 days. Rebeat before using.
  • For added flavor, you can toast the peanut butter slightly before mixing.
  • Use smooth peanut butter for the creamiest frosting; chunky peanut butter will change the texture.
