Delight in these rich Peanut Butter Oreo Bars featuring a crunchy Oreo cookie base, a smooth peanut butter layer, and a luscious chocolate topping. Perfectly balanced in sweetness and texture, these bars are an irresistible treat for any dessert lover.


Ingredients

Scale

Oreo Base

  • 15 Oreo cookies, not double stuffed
  • 3 tablespoons unsalted butter, melted (42 grams)

Peanut Butter Layer

  • 1/4 cup unsalted butter, softened (56 grams)
  • 3 tablespoons brown sugar, light or dark
  • 1/4 teaspoon salt, omit if using salted butter
  • 1 cup smooth peanut butter
  • 1 2/3 cup powdered sugar, sifted (183 grams)

Chocolate Topping

  • 6 ounces semi-sweet chocolate (170 grams), or your favorite variety
  • 2 teaspoons shortening, or 1/2 teaspoon vegetable oil


Instructions

  1. Prepare the Pan: Line an 8×8 inch (20×20 cm) pan with parchment paper or aluminum foil, leaving an overhang around the sides to easily lift out the bars later.
  2. Make the Oreo Crust: Crush the Oreo cookies with a food processor until fine crumbs form, or place them in a freezer bag and crush with a rolling pin. Mix the crushed cookies with melted butter, then press firmly into the bottom of the prepared pan to form an even crust.
  3. Create the Peanut Butter Layer: Beat softened butter and brown sugar together until smooth. Add peanut butter and salt, mixing until no lumps remain. Gradually add sifted powdered sugar, about 1/2 cup at a time, mixing thoroughly until the mixture is stiff and no longer sticky. Spread and press the peanut butter mixture evenly over the Oreo crust using a spatula or wax paper.
  4. Prepare the Chocolate Topping: Chop the chocolate into fine pieces. Melt the chocolate in a microwave on medium power in 45-second intervals, stirring between each until completely melted, or melt over a double boiler. Stir in the shortening or vegetable oil until smooth. Pour this warm chocolate over the peanut butter layer and smooth the surface.
  5. Set and Slice: Allow the chocolate to harden at room temperature or in the refrigerator (noting fridge may cause discoloration). When the chocolate is about 90% hardened, score with a sharp knife to mark slices. Once fully set, lift the bars out using the parchment overhang and slice into 16 squares with a sharp, thin knife.

Notes

  • Use smooth, commercially prepared peanut butter to ensure the right texture; avoid natural peanut butters where oil separates.
  • Nutrition details are estimates based on slicing the pan into 16 equal bars.
  • Store bars in an airtight container at room temperature or in the fridge to maintain freshness.
