Ingredients

Scale

Peanut Butter Dough

  • 1/2 cup creamy peanut butter
  • 1/4 cup butter, softened
  • 1/2 cup brown sugar
  • 1 egg
  • 1 tsp vanilla extract
  • 1 cup all-purpose flour
  • 1/2 tsp baking soda
  • 1/4 tsp salt

Brownie Dough

  • 1/2 cup butter, melted
  • 1 cup white sugar
  • 1/3 cup cocoa powder
  • 1 egg
  • 1 tsp vanilla extract
  • 3/4 cup all-purpose flour
  • 1/4 tsp baking powder
  • 1/4 tsp salt
  • 1/2 cup chocolate chips

Instructions

  1. Make the peanut butter dough: In a bowl, beat the peanut butter, softened butter, and brown sugar together until the mixture is light and fluffy. Next, beat in the egg and vanilla extract. In another bowl, whisk the flour, baking soda, and salt, then gradually add this dry mixture into the wet ingredients and mix until just combined.
  2. Make the brownie dough: In a separate bowl, whisk together melted butter and white sugar until smooth. Beat in the cocoa powder until fully incorporated, then add the egg and vanilla extract. Fold in the flour, baking powder, salt, and chocolate chips until no dry streaks remain.
  3. Chill the doughs: Refrigerate both the peanut butter and brownie doughs for 30 minutes to firm up, which will make them easier to handle and swirl.
  4. Form and swirl the cookies: Using a spoon or cookie scoop, take 1-2 tablespoon portions of each dough and place them side by side on a parchment-lined baking sheet. Use a toothpick or skewer to gently swirl the two doughs together, creating a beautiful marble pattern without fully mixing them.
  5. Bake: Preheat your oven to 350°F (175°C). Bake the cookies for 9 to 11 minutes until the tops develop a light crackle and the edges are set but centers remain soft.
  6. Cool: Let the cookies cool on the baking sheet for 5 to 10 minutes to finish setting, then transfer them to a wire rack to cool completely before serving. Enjoy your peanut butter brownie swirl cookies!

Notes

  • Chilling the dough is essential to prevent spreading and to make handling easier when swirling the two doughs together.
  • Do not overmix the dough to ensure tender, chewy cookies.
  • Use parchment paper or silicone baking mats to prevent sticking and help with easy cleanup.
  • For extra texture, you can add chopped peanuts or walnuts to the peanut butter dough.
  • Store cookies in an airtight container at room temperature for up to 5 days or freeze for longer storage.
