Ingredients

Scale

Dry Ingredients

  • 1 ¾ cups (217g) all purpose flour
  • ¾ cup (60g) unsweetened cocoa powder
  • 2 cups (400g) granulated sugar
  • 1 teaspoon salt

Wet Ingredients

  • 5 large eggs
  • 1 cup (237ml) vegetable oil

Add-ins

  • 1 cup (170g) peanut butter chips
  • 24 miniature Reese’s Peanut Butter Cups, unwrapped
  • 1 cup Reese’s Pieces


Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with foil and spray it generously with nonstick cooking spray to ensure the brownies don’t stick.
  2. Mix Dry Ingredients: In a large bowl, whisk together the flour, unsweetened cocoa powder, granulated sugar, and salt until evenly combined. This ensures a uniform chocolate flavor throughout the brownies.
  3. Add Wet Ingredients: Stir in the eggs and vegetable oil to the dry mixture. Mix thoroughly until the batter is smooth and all ingredients are well incorporated with no flour streaks.
  4. Incorporate Peanut Butter Chips: Fold in the peanut butter chips gently into the batter, distributing them evenly to add delicious peanut butter pockets throughout the brownies.
  5. Layer Batter and Reese’s Cups: Spread half of the batter evenly in the prepared pan. Arrange the 24 miniature Reese’s Peanut Butter Cups on top of this layer. You can place them whole or chop them if you prefer smaller pockets of peanut butter flavor.
  6. Top with Remaining Batter and Pieces: Spread the remaining batter over the peanut butter cups layer until fully covered. Sprinkle 1 cup of Reese’s Pieces evenly over the top to add texture and bursts of peanut butter candy flavor.
  7. Bake the Brownies: Place the pan in the preheated oven and bake for 20-26 minutes. The brownies are done when they just stop jiggling slightly in the center; they are best when slightly underbaked to maintain a fudgy texture.
  8. Cool and Serve: Allow the brownies to cool completely before slicing. This helps the brownies set and makes them easier to cut into neat squares.
  9. Storage: Store the brownies in an airtight container for up to 3 days at room temperature, or freeze them for up to one month to enjoy later.

Notes

  • Ensure not to overbake the brownies—slightly underbaked brownies will be fudgier and more delicious.
  • You can chop the Reese’s Peanut Butter Cups if you prefer smaller pockets of peanut butter throughout the brownies.
  • Store leftovers in an airtight container to maintain freshness or freeze for longer storage.
  • Allow brownies to cool completely before slicing to prevent crumbling.
