Peanut Butter Cup Frosting

  • Author: Cookies & Cups



  • 16 regular sized peanut butter cups
  • 3/4 cup butter, room temperature
  • 2 cups powdered sugar


  1. In blender or food processor pulverize the peanut butter cups until they are crumbly paste consistency. You don’t want any chunks.
  2. In bowl of stand mixer beat butter until smooth. Add in peanut butter cup mixture and beat until evenly combined.
  3. Turn mixer to low and add in powdered sugar. Turn mixer up and beat until combined evenly and fluffy.


I made this frosting on the thick side because I am uing it in a whoopie pie, but if you prefer it to be a little softer, add in 1-2 Tbsp of milk or heavy cream.
