Ingredients
- 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
- 1/2 cup butter, melted
- 1 cup white sugar
- 1/3 cup cocoa powder
- 1 egg
- 1 tsp vanilla
- 3/4 cup all-purpose flour
- 1/4 tsp baking powder
- 1/4 tsp salt
- 1/2 cup chocolate chips
Instructions
- Step 1: Make the peanut butter dough by beating the peanut butter, softened butter, and brown sugar together until light and fluffy. Add the egg and vanilla extract, mixing well. In a separate bowl, whisk the flour, baking soda, and salt, then gradually mix this into the wet ingredients until just combined.
- Step 2: Prepare the brownie dough by whisking the melted butter and white sugar together. Beat in the cocoa powder until smooth, then add the egg and vanilla. Fold in the flour, baking powder, salt, and chocolate chips until the dough has no dry streaks.
- Step 3: Chill both doughs in the refrigerator for 30 minutes. Once chilled, scoop 1 to 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 doughs together, creating a marble pattern.
- Step 4: Bake the cookies at 350°F (175°C) for 9 to 11 minutes, until the tops are lightly crackly and the edges are just set. The centers will remain slightly soft.
- Step 5: Let the cookies cool on the baking sheet for 5 to 10 minutes before transferring them to a wire rack to cool completely. Enjoy your delicious swirl cookies!
Tips & Variations
- For extra peanut butter flavor, sprinkle a few chopped peanuts on top before baking.
- Try using chunky peanut butter instead of creamy for added texture.
- Substitute chocolate chips with chopped nuts or butterscotch chips for a different twist.
- If you prefer softer cookies, reduce the baking time by a minute or two.
Storage

FAQs
Can I use natural peanut butter for this recipe?
Yes, you can; however, natural peanut butter is often oilier and may alter the dough consistency slightly. If needed, add a little extra flour to balance the dough.
Why are the centers of the cookies still soft after baking?
These cookies are meant to have soft centers for a fudgy texture, similar to brownies. If you prefer them firmer, bake for an additional 1-2 minutes, but be careful not to overbake.

Ingredients
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
- Make the peanut butter dough: In a mixing bowl, beat together the creamy peanut butter, softened butter, and brown sugar until the mixture is light and fluffy. Next, add the egg and vanilla extract, mixing well to combine. In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually incorporate these dry ingredients into the wet peanut butter mixture, mixing just until combined to form the peanut butter dough.
- Make the brownie dough: In another bowl, whisk together the melted butter and white sugar until smooth. Stir in the cocoa powder until fully blended. Beat in the egg and vanilla extract. Then fold in the all-purpose flour, baking powder, salt, and chocolate chips, mixing gently until no dry streaks remain, creating a thick brownie batter.
- Chill the doughs: Cover both the peanut butter and brownie doughs and refrigerate for 30 minutes. This chilling helps the doughs firm up and makes them easier to work with.
- Form and swirl cookies: Using a tablespoon or small scoop, portion out 1 to 2 tablespoons of each dough. Place the peanut butter and brownie dough side by side on a parchment-lined baking sheet. Using a toothpick or skewer, gently swirl the two doughs together in a marble pattern, being careful not to overmix.
- Bake the cookies: Preheat your oven to 350°F (175°C). Bake the cookies for 9 to 11 minutes until the top surfaces are lightly cracked and the edges have just set, while the centers remain slightly soft.
- Cool and serve: Remove the cookies from the oven and allow them to cool on the baking sheet for 5 to 10 minutes. Then transfer to a wire rack to cool completely before enjoying your peanut butter brownie swirl cookies.
Notes
- For best results, use room temperature butter for the peanut butter dough and melted butter for the brownie dough as specified.
- You can substitute smooth peanut butter with chunky if you prefer a bit of texture.
- Refrigerating the dough helps maintain the swirl definition and prevents the doughs from mixing too much during baking.
- The cookies will be soft in the center when done; avoid overbaking to keep them fudgy and moist.
- Store cooled cookies in an airtight container at room temperature for up to 5 days or freeze for longer storage.
