Ingredients
For the 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
For the Brownie Dough
- 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
Directions

Make the Peanut Butter Dough
- In a large mixing bowl, beat together the creamy peanut butter, softened butter, and brown sugar using a hand mixer or stand mixer until light and fluffy.
- Add the egg and vanilla extract and beat until fully incorporated.
- In a separate bowl, whisk together the flour, baking soda, and salt.
- Gradually add the dry ingredients to the wet mixture. Mix on low speed until just combined. Do not overmix.
- Set aside.
Make the Brownie Dough
- In a second bowl, whisk the melted butter and white sugar together until smooth.
- Add the cocoa powder and whisk until fully incorporated.
- Mix in the egg and vanilla extract.
- In another small bowl, whisk together the flour, baking powder, and salt.
- Fold the dry ingredients into the wet mixture using a spatula until no dry streaks remain.
- Stir in the chocolate chips.
Chill the Doughs
- Cover both doughs and chill in the refrigerator for 30 minutes. This helps firm the doughs and ensures clean swirls during baking.
Form the Swirl Cookies
- Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
- Using a cookie scoop or tablespoon, scoop 1–2 tablespoons of each dough (peanut butter and brownie).
- Press the two doughs together gently into one rough ball. Place on the baking sheet.
- Use a toothpick or skewer to gently swirl the doughs together on top, creating a marbled effect. Don’t over-swirl—2–3 swirls is perfect.
Bake
- Bake the cookies for 9–11 minutes, or until the tops are crackly and the edges are just set.
- The centers should still be slightly soft and appear slightly underbaked—that’s what gives them a gooey center.
Cool and Serve
- Let the cookies cool on the baking sheet for 5–10 minutes to finish setting.
- Transfer to a wire rack to cool completely.
- Enjoy warm or store for later!
Pro Tips and Variations
- Room temperature butter and egg help both doughs mix smoothly.
- Don’t overmix the two doughs when swirling—distinct swirls are key to the look and texture.
- Use a cookie scoop for even portion sizes and consistent baking.
- Chill time ensures the cookies don’t spread too much.
- Try swapping chocolate chips for peanut butter chips in the brownie dough.
Serving Suggestions
- Serve warm with a glass of cold milk
- Drizzle with melted peanut butter or chocolate
- Sandwich around a scoop of vanilla ice cream
- Pack in gift boxes or jars for a beautiful homemade gift
