Print Recipe

Ingredients

  • 2 sticks 226gr unsalted butter, at room temperature
  • 1 cup 260gr creamy peanut butter (Note 1)
  • 2 cups 250gr powdered sugar
  • 1 teaspoon pure vanilla extract
  • ¼ teaspoon coarse kosher salt

Instructions

  • In a mixing bowl with a paddle attachment, combine butter and peanut butter and beat on medium high heat for about 2 minutes, or until pale and fluffy. Scrape the sides and bottom of the bowl with a silicone spatula half way through. TIP: Incorporating as much air into the butter mixture before adding sugar and flavorings ensures light and fluffy frosting. If the butter mixture is not whipped well, the frosting will be heavy, kind of greasy and won't hold its shape well.
  • Add powdered sugar, vanilla extract and salt and continue beating until the frosting is nice and smooth and fluffy, about 2 more minutes.

Notes

Note 1: Choose conventional creamy peanut butter (like Jif or Skippy) for creamy and smooth frosting, because natural 100% peanut butters tend to separate and has thinner consistency.
Make-Ahead Tip: Store the frosting in an airtight container in refrigerator for up to 1 week, or in freeze for up to 3 months. Thaw the frozen frosting in the fridge overnight. Bring the frosting to room temperature and whip it again in the mixer until fluffy.
Yield: This recipe makes enough frosting for 24 cupcakes (moderately frosted), two-layer 9-inch cake, or four-layer 7-inch cake.
