Ingredients

  • 1 cup unsweetened cocoa powder
  • 1 cup sugar granulated
  • 1 cup brown sugar
  • 1/2 cup unsalted butter melted
  • 1/2 cup peanut butter mixed into the batter
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/2 teaspoon salt fine
  • 1/2 teaspoon baking powder
  • 1/2 cup creamy peanut butter for swirling

Instructions

  • Preheat your oven to 350°F (175°C). Grease a 9x9 inch baking pan or line it with parchment paper.
  • In a large mixing bowl, whisk together melted butter, sugar, and brown sugar until smooth and glossy.
  • Add eggs one at a time, beating well after each addition. Stir in vanilla extract and 1/2 cup peanut butter until fully incorporated.
  • In a separate bowl, sift together cocoa powder, all-purpose flour, salt, and baking powder.
  • Gradually fold dry ingredients into wet mixture using a rubber spatula. Fold just until no streaks remain.
  • Scrape the batter into the prepared pan and smooth the top with a spatula.
  • Spoon dollops of the remaining 1/2 cup creamy peanut butter over the batter. Using a toothpick or skewer, gently swirl the peanut butter through the batter to create a marbled effect.
  • Bake for 25-30 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs but no wet batter.
  • Allow brownies to cool completely in the pan on a wire rack before slicing and serving.

Notes

  • Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
  • Use crunchy peanut butter for added texture, warming it slightly to swirl easier.
