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, preferably Dutch-processed
  • 1/4 tsp salt
  • 1/2 cup (130g) creamy peanut butter
  • 1/3 cup (60g) chocolate chips (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking pan with butter or line it with parchment paper.
  2. Mix the melted butter with granulated sugar and brown sugar in a medium bowl until combined and slightly cooled, about 2 minutes.
  3. Add the eggs one at a time, whisking well after each addition. Stir in vanilla extract until the batter is shiny and slightly thick.
  4. In a separate bowl, sift together the flour, cocoa powder, and salt.
  5. Gently fold the dry ingredients into the wet mixture using a spatula, mixing just until no streaks remain.
  6. Pour half the brownie batter into the prepared pan, smoothing it out evenly.
  7. Warm the peanut butter briefly (about 20 seconds in the microwave) so it’s easier to swirl. Dollop the peanut butter over the batter in spoonfuls.
  8. Pour the remaining batter over the peanut butter dollops. Using a knife or skewer, swirl the peanut butter into the batter with gentle figure-eight motions to create marbled ribbons. Do not over-swirl.
  9. Sprinkle chocolate chips evenly on top if using.
  10. 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. The edges will be set and crisp.
  11. Let brownies cool completely on a wire rack before cutting.

Notes

Use a metal pan for crispier edges. Warm peanut butter slightly to swirl easily. Do not overmix batter to avoid cakey brownies. Let brownies cool completely before cutting for clean slices. For gluten-free, substitute almond flour. For dairy-free, use coconut oil and vegan chocolate chips.
