Peanut Butter frosting 

Posted on

For my husband’s 40th birthday party he requested chocolate peanut butter cupcakes. I ended up making chocolate cupcakes with butterfinger pieces inside, with this peanut butter frosting, and sprinkled with butterfinger. He loved them. 


  • 1 1/2 cup creamy peanut butter
  • 2 sticks (1 cup) unsalted butter, room temp
  • 1 tsp vanilla extract 
  • 3 cups powdered sugar 
  • 1/4 tsp salt
  • 3 tbsp whole milk 
  • 1/4 cup crushed butterfinger (optional)


  1. In an electric mixer, beat the peanut butter and butter on medium until completely smooth.
  2. Add vanilla. 
  3. Reduce speed to low and add in the remaining ingredients, beating until fully incorporated. 
  4. Increase speed to medium high and beat the frosting for 1-2 minutes until light and fluffy. 
  5. Once cake or cupcakes are completely cooled you can spread or pipe frosting.

Side notes:

  1. This batch makes enough for a dozen cupcakes. 
  2. I sprinkled them with crushed Butterfinger that I ran through the food processor. About 12 mini butterfinger. 
  3. Many people said the frosting tasted like Reeses peanut butter cups.
