Ingredients
  

  • 1 cup unsalted butter softened to room temperature 226g
  • 1 cup creamy peanut butter 245g
  • 3 cups powdered sugar 375g
  • 1 teaspoon vanilla extract
  • ½ teaspoon salt
  • 2 Tablespoons milk add more if needed for desired consistency

Instructions
 

  • Start by placing 1 cup of unsalted butter, which you've let soften to room temperature, into a large mixing bowl. Add in the creamy peanut butter. Using an electric mixer, beat these two together until they're completely creamy.

  • Now, it's time to gradually add in the powdered sugar, keeping the mixer on a low speed to avoid a sugar snowstorm in your kitchen. After each addition, scrape down the sides and bottom of the bowl. Aim for a smooth, clump-free consistency.

  • Stir in that teaspoon of vanilla extract for a hint of warmth and the ½ teaspoon of salt to balance the sweetness.

  • With the mixer still on low speed, pour in the 2 tablespoons of milk. It makes the frosting smooth and spreadable. If it seems a bit stiff, add a touch more milk, just a teaspoon at a time. Once you've got the consistency you want, crank up the speed to high and beat for another 30 seconds to add fluffiness.
