Ingredients

For the Brownies:

  • 90 g all-purpose flour
  • 200 g granulated sugar
  • 110 g light brown sugar
  • 40 g unsweetened natural or Dutch process cocoa powder
  • ½ tsp fine sea salt
  • ½ tsp baking powder
  • 170 g unsalted butter melted
  • 3 large eggs
  • 1 tsp vanilla extract

For the Peanut Butter Swirl:

  • 125 g creamy peanut butter
  • 30 g unsalted butter melted
  • 30 g powdered sugar
  • 1 tsp vanilla extract
  • ¼ tsp fine sea salt

Instructions

  • Preheat the oven to 350°F (180°C). Grease an 8×8–inch pan and line the pan with parchment paper, leaving an overhang on all sides.
  • In a large bowl, whisk together the flour, granulated sugar, light brown sugar, cocoa powder, salt, and baking powder. In a medium bowl, add the butter, eggs, and vanilla and whisk until well combined. Add the wet ingredients to the dry ingredients and mix until just combined then set aside.
  • In a small bowl, whisk together the peanut butter, butter, powdered sugar, vanilla, and salt until well combined. 
  • Drop large spoonfuls of the brownie batter randomly into the prepared pan. Top with random spoonfuls of all of the peanut butter batter. Drop random spoonfuls of the remaining chocolate batter over any bare or heavy peanut butter spots. Using a knife, swirl the batters together then bake for 30-35 minutes.
  • Remove from the oven and place on a wire rack to cool completely in the pan before cutting into squares. Cover and store leftover brownies at room temperature for up to 1 week.
