  • 9×9 inch baking pan
  • Parchment paper
  • Mixing bowls
  • Whisk
  • Spatula
  • Measuring cups and spoons
  • Toothpick or skewer


  • For the brownie batter:
    • 1/2 cup unsalted butter
    • 1 cup granulated sugar
    • 2 large eggs
    • 1 teaspoon vanilla extract
    • 1/3 cup unsweetened cocoa powder
    • 1/2 cup all-purpose flour
    • 1/4 teaspoon salt
    • 1/4 teaspoon baking powder
  • For the peanut butter swirl:
    • 1/2 cup creamy peanut butter
    • 1/4 cup powdered sugar
    • 2 tablespoons melted butter
    • 1/2 teaspoon vanilla extract


  1. Preheat the oven: Preheat your oven to 350°F (175°C). Line the baking pan with parchment paper, leaving some overhang for easy removal.
  2. Prepare the brownie batter: In a microwave-safe bowl, melt the unsalted butter. Stir in the granulated sugar, eggs, and vanilla extract until well combined.
  3. Add the cocoa powder, all-purpose flour, salt, and baking powder to the wet ingredients, stirring until the batter is smooth and well mixed.
  4. Make the peanut butter swirl: In a separate bowl, mix together the creamy peanut butter, powdered sugar, melted butter, and vanilla extract until smooth and creamy.
  5. Assemble the brownies: Pour the brownie batter into the prepared baking pan, spreading it into an even layer.
  6. Drop spoonfuls of the peanut butter mixture onto the brownie batter. Use a toothpick or skewer to swirl the peanut butter into the brownie batter, creating a marbled effect.
  7. Bake: Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
  8. Cool: Allow the brownies to cool in the pan on a wire rack. Once cooled, use the parchment paper overhang to lift the brownies out of the pan and onto a cutting board. Cut into 16 squares.

Enjoy these rich and indulgent Peanut Butter Swirl Brownies, a perfect blend of chocolatey goodness and creamy peanut butter in every bite!
