Ingredients

Scale

Peanut Butter Dough

  • ½ cup creamy peanut butter
  • ¼ cup butter, softened
  • ½ cup brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • ½ teaspoon baking soda
  • ¼ teaspoon salt

Brownie Dough

  • ½ cup butter, melted
  • 1 cup white sugar
  • ⅓ cup cocoa powder
  • 1 large egg
  • 1 teaspoon vanilla extract
  • ¾ cup all-purpose flour
  • ¼ teaspoon baking powder
  • ¼ teaspoon salt
  • ½ cup chocolate chips

Instructions

  1. Prepare the Peanut Butter Dough: In a large mixing bowl, cream the peanut butter, softened butter, and brown sugar until smooth and creamy. Add the egg and vanilla extract, mixing until fully incorporated. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually combine the dry ingredients with the wet mixture, stirring until a soft dough forms. Cover the dough and set aside.
  2. Prepare the Brownie Dough: In another mixing bowl, whisk the melted butter and sugar until smooth. Stir in the cocoa powder, then add the egg and vanilla extract, mixing well. In a separate bowl, mix the flour, baking powder, and salt. Slowly incorporate the dry ingredients into the wet mixture until the dough is thick and cohesive. Gently fold in the chocolate chips for added richness.
  3. Form the Swirled Cookies: Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper. Scoop a small amount of peanut butter dough and brownie dough, gently pressing them together to form a swirled ball. Roll into a ball, keeping the swirls distinct. Place the dough balls on the baking sheets, spacing about 2 inches apart. Flatten slightly with your hand.
  4. Bake the Cookies: Bake for 10–12 minutes, or until the edges are firm but the centers remain soft. Allow the cookies to rest on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • For best results, use room temperature butter for the peanut butter dough to help with creaming.
  • Do not overbake to maintain a soft center.
  • You can substitute creamy peanut butter with natural peanut butter, but the texture may vary slightly.
  • Store cookies in an airtight container at room temperature for up to 5 days.
  • For a more pronounced swirl effect, chill the dough balls briefly before baking.
