Ingredients

Scale

For the Brownies:

  • 1 cup (2 sticks) unsalted butter, melted
  • 1 ½ cups granulated sugar
  • 1 cup brown sugar, packed
  • 4 large eggs
  • 1 tablespoon vanilla extract
  • 1 cup unsweetened cocoa powder
  • 1 cup all-purpose flour
  • ½ teaspoon salt
  • 1 cup semi-sweet chocolate chips (optional)

For the Peanut Butter Swirl:

  • ¾ cup creamy peanut butter
  • 2 tablespoons powdered sugar (optional, for sweetness)

Instructions

  • Preheat Oven:

    • Preheat your oven to 350°F (175°C).
    • Grease or line a 9×13-inch baking pan with parchment paper for easy removal.
  • Make the Brownie Batter:

    • In a large bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth.
    • Add eggs one at a time, beating well after each addition. Stir in vanilla extract.
    • Sift in cocoa powder, flour, and salt. Mix until just combined—don’t overmix!
    • Fold in chocolate chips (if using).
  • Create the Peanut Butter Swirl:

    • In a separate bowl, mix peanut butter and powdered sugar until smooth.
  • Assemble the Brownies:

    • Pour the brownie batter into the prepared baking pan and spread evenly.
    • Drop spoonfuls of the peanut butter mixture on top of the brownie batter.
    • Use a knife or skewer to gently swirl the peanut butter into the batter—don’t overdo it for best visual effect.
  • Bake:

    • Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (but not wet batter).
    • Let cool completely in the pan before slicing for clean cuts.
  • Serve:

    • Slice into squares and enjoy on their own or with a scoop of vanilla ice cream!

Notes

  • Use crunchy peanut butter for added texture.
  • Add a sprinkle of sea salt on top before baking for a sweet-and-salty combo.
  • Store in an airtight container at room temperature for up to 4 days, or freeze for up to 2 months.
