  • ½ cup unsweetened cocoa powder like Ghirardelli's
  • ¼ teaspoon salt

PEANUT BUTTER FILLING Or 12 full-size peanut butter cups unwrapped

  • ¾ cup creamy peanut butter
  • ½ cup powdered sugar

Chocolate Peanut Butter Frosting Layer

  • 1 cup semi-sweet chocolate chips
  • 1 tablespoon peanut butter

Instructions

  • INSTRUCTIONS
  • Preheat oven to 350°F. Line an 8-inch square baking dish with parchment paper or aluminum foil, leaving some overhang for easy removal. Spray with nonstick cooking spray and set aside.

PEANUT BUTTER FILLING

  • Mix butter, peanut butter and powdered sugar together until smooth. Set aside.

BROWNIES

  • In a large mixing bowl, whisk together the melted butter and granulated sugar until well combined. Mix in the eggs and vanilla extract and whisk until fully combined.
  • Whisk together the flour, cocoa powder, and salt into the wet ingredients and mix until just combined, scraping down the sides of the bowl as needed.

BOTTOM BROWNIE LAYER

  • Pour half of the brownie batter into the prepared baking pan

PEANUT BUTTER LAYER

  • Place spoonfuls of the peanut butter filling on top of the brownie batter, then spread out using back of spoon or offset spatula.

TOP BROWNIE LAYER

  • Add the remaining brownie batter on top by the spoonfuls and spread into one even layer, covering the peanut butter layer.
  • Bake 350°F for 30-35 minutes or until the tops of the brownies look set. Remove from the oven and transfer to a wire rack to cool completely.

Chocolate Peanut Butter Frosting Layer

  • Once the brownies are cooled, melt chocolate chips in microwave for 40 seconds, stir. Microwave an additional 40 seconds and stir. Add in peanut butter and continue stirring until chocolate is completed melted. Pour on top of brownies and spread with back of spoon or offset spatula. Let chocolate set at room temperature and slice into 16 squares for your peanut butter brownie indulgence!

Notes

  • Store brownies in an airtight container @ room temperature for up to four days. Brownies may also be frozen for up to 3 months, thaw overnight in the refrigerator and bring to room temperature before serving.
  • Peanut butter cups can be used instead of the peanut butter layer if desired.
