Description

Light, creamy, and melt-in-your-mouth dreamy—this peanut butter frosting is pure magic. Unlike dense versions, this one is whipped to cloud-like perfection, making it just as irresistible by the spoonful as it is on cupcakes or cakes. With a perfect balance of sweet, salty, and nutty, it’s the frosting that transforms simple desserts into unforgettable showstoppers.


Ingredients

Scale
  • 2 cups creamy peanut butter (Jif or Skippy work best)

  • 1 cup (2 sticks) unsalted butter, softened

  • 4 cups confectioners’ sugar, sifted

  • 6 tbsp milk (more as needed)

  • 1 tsp vanilla extract

  • Pinch of sea salt

  • Optional: ¼ cup cream cheese for tang & stability


Instructions

  • Whip base: Beat butter + peanut butter for 2–3 min until pale and fluffy.

  • Add sugar: On low speed, add confectioners’ sugar ½ cup at a time. Scrape bowl.

  • Adjust consistency: Add milk gradually until smooth and spreadable.

  • Flavor boost: Mix in vanilla + pinch of salt (and cream cheese if using).

  • Final whip: Beat 1–2 min on medium-high until light, airy, and silky.

  • Frost: Use immediately on cooled cakes, cupcakes, or brownies.

Notes

  • Chocolate PB: Swap 1 cup sugar for ¾ cup cocoa powder.

  • Honey Cinnamon: Add 3 tbsp honey + 1 tsp cinnamon.

  • Maple Bourbon: Replace 5 tbsp milk with 3 tbsp maple syrup + 2 tbsp bourbon.
