Ingredients

Scale
  • 1 cup (227g) unsalted butter, melted
  • 1 ½ cups (300g) granulated sugar
  • 3 large eggs, room temperature
  • 2 tsp pure vanilla extract
  • 1 cup (120g) all-purpose flour, sifted (or almond flour for gluten-free)
  • ¾ cup (75g) unsweetened cocoa powder, sifted
  • ½ tsp salt
  • ¼ tsp baking powder
  • 1 cup (250g) creamy peanut butter (natural or preferred brand)
  • ½ cup (60g) powdered sugar
  • Pinch of salt (if using unsalted peanut butter)
  • ¾ cup (180ml) heavy cream
  • 1 ½ cups (270g) bittersweet or semisweet chocolate chips
  • 2 tbsp (28g) unsalted butter, softened

Instructions

  1. Preheat your oven to 350°F (175°C) and grease a 9×9 inch pan or line it with parchment paper.
  2. Prepare the peanut butter filling by stirring together peanut butter, powdered sugar, and a pinch of salt until smooth and thick. Set aside.
  3. In a large bowl, whisk melted butter and granulated sugar until combined but not grainy. Add eggs one at a time, whisking well after each addition, then stir in vanilla extract.
  4. In another bowl, sift together flour, cocoa powder, salt, and baking powder.
  5. Gradually fold dry ingredients into the wet mixture until just combined, being careful not to overmix.
  6. Pour half the brownie batter evenly into the prepared pan. Dollop the peanut butter filling in spoonfuls over the batter and gently spread it out, leaving a small border around edges.
  7. Spoon the remaining brownie batter over the peanut butter layer, covering as evenly as possible.
  8. Bake for 30-35 minutes until a toothpick inserted near the edge comes out with a few moist crumbs but no wet batter. Avoid overbaking.
  9. Cool completely in the pan for about 1 hour.
  10. Prepare the chocolate ganache by heating heavy cream in a saucepan until it just begins to simmer. Remove from heat and pour over chocolate chips in a heatproof bowl. Let sit for 2 minutes, then stir until smooth. Stir in softened butter until glossy.
  11. Pour ganache over cooled brownies and spread evenly. Optionally sprinkle chopped roasted peanuts or a pinch of sea salt on top.
  12. Chill the brownies in the refrigerator for at least 30 minutes to set the ganache.
  13. Cut using a sharp knife warmed in hot water for clean slices and serve.

Notes

Do not overbake to keep the peanut butter center gooey. Use room temperature eggs for better batter texture. Sift cocoa and flour to avoid clumps. Warm ganache gently if it thickens too much while spreading. Chill ganache-topped brownies before slicing for clean cuts. Use a sharp serrated knife warmed in hot water for best slicing results.
