Peanut Butter Cup Oreo Fudge

Prep Time: 15 minutes
Course: Dessert
Cuisine: American
Servings: 64 (1-inch) pieces
This easy, microwave peanut butter fudge is stuffed with peanut butter cups and Oreo cookie pieces.


  • 8 oz unsalted butter
  • 1 cup creamy store-bought peanut butter
  • 1 lb powdered sugar
  • 10 Oreo cookies I used the limited edition Reese's peanut butter cup flavored
  • 10 peanut butter cups


  1. In a large microwave-safe bowl, add butter and peanut butter. Microwave for 1 minute and stir. Microwave for about another 1 minute and stir again until mixture is completely smooth. Add in powdered sugar and stir until completely smooth and no powdered sugar chunks remain.

  2. Chop Oreos and peanut butter cups. Line an 8 x 8 baking pan with parchment paper. Add half of the chopped Oreos and peanut butter cups to the bottom of the lined pan, spreading across evenly. Pour fudge on top, spreading across evenly and smoothing out surface. Add remaining Oreos and peanut butter cup pieces on top, pressing down gently so they partially sit inside the fudge. Refrigerate for several hours to set. Slice with a sharp knife to serve.
