Ingredients

Scale
  • 1/2 cup (115g) unsalted butter, melted
  • 1 cup (200g) granulated sugar
  • 1/2 cup (100g) brown sugar, packed
  • 2 large eggs, room temperature
  • 1 tsp vanilla extract
  • 3/4 cup (95g) all-purpose flour
  • 1/2 cup (50g) unsweetened cocoa powder, sifted
  • 1/4 tsp salt
  • 1/2 cup (130g) peanut butter, creamy or chunky
  • 1 cup mini peanut butter cups, roughly chopped
  • 1/2 cup chopped roasted peanuts, unsalted
  • Optional: sea salt flakes for sprinkling on top

Instructions

  1. Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper, leaving some overhang for easy removal.
  2. In a medium bowl, combine the melted unsalted butter with the granulated and brown sugars. Whisk until smooth and glossy, about 1-2 minutes.
  3. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
  4. In a separate bowl, sift together the all-purpose flour, cocoa powder, and salt.
  5. Gradually add the dry ingredients to the wet mixture, folding gently with a spatula until just combined. Avoid overmixing.
  6. Warm the peanut butter slightly (about 15 seconds in the microwave) so it’s easier to mix. Dollop spoonfuls over the brownie batter and gently swirl with a knife or spatula to create marbled pockets.
  7. Fold in about 3/4 cup of the chopped peanut butter cups into the batter, reserving the rest for the topping.
  8. Spread the batter evenly in your prepared pan. Sprinkle the chopped roasted peanuts and the remaining chopped peanut butter cups on top, pressing lightly so they stick.
  9. Bake for 25-30 minutes. Start checking at 25 minutes by inserting a toothpick near the center — it should come out with moist crumbs but not wet batter.
  10. Let the brownies cool completely in the pan on a wire rack.
  11. Once cooled, use the parchment overhang to lift the brownies out. Cut into squares and serve.

Notes

Do not overbake to keep brownies fudgy; use the toothpick test. Warm peanut butter slightly before swirling to avoid separation. Sift cocoa powder with flour to prevent lumps. Press chopped peanuts and peanut butter cups lightly into batter before baking to keep topping intact. Best served fully cooled for flavors to meld.
