Tips & Variations
- For a more pronounced swirl effect, gently fold the doughs together rather than mixing completely.
- Substitute creamy peanut butter with crunchy for extra texture.
- Add chopped peanuts or chocolate chips to either dough for added flavor and crunch.
- If you prefer a sweeter cookie, increase the sugar in either dough slightly.
Storage
Store cookies in an airtight container at room temperature for up to 5 days. For longer storage, keep them in the refrigerator for up to 2 weeks or freeze for up to 3 months. To reheat, warm in the oven at low heat for a few minutes to restore softness.

FAQs
Can I use natural peanut butter instead of creamy?
Yes, you can use natural peanut butter, but it may change the texture slightly due to its thinner consistency. Consider chilling the dough before baking to help maintain shape.
Can I make these cookies gluten-free?
Yes, replacing the all-purpose flour with a gluten-free flour blend that measures cup-for-cup will work well. Just be sure the blend contains xanthan gum or a similar binder for best results.

Ingredients
Peanut Butter Cookie Batter
- 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

Brownie Batter
- 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
Instructions
- Prepare the Peanut Butter Batter: In a mixing bowl, cream together the softened butter and creamy peanut butter until smooth. Add the brown sugar and beat until fluffy. Mix in the egg and vanilla extract until well combined. Gradually add the flour, baking soda, and salt, folding gently to create a soft cookie dough.
- Prepare the Brownie Batter: In a separate bowl, whisk together the melted butter and white sugar until combined. Stir in the cocoa powder, egg, and vanilla extract until smooth. Fold in the flour, baking powder, and salt to form a thick batter.
- Combine and Swirl: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Alternately drop spoonfuls of peanut butter batter and brownie batter onto the prepared sheet. Using a knife or skewer, swirl the two batters together gently to create a marbled effect, taking care not to overmix.
- Bake the Cookies: Bake the cookies in the preheated oven for 10-12 minutes, or until the edges are set and the centers are slightly soft. Remove from the oven and allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Notes
- Make sure not to over-swirl the batters to maintain a distinct peanut butter and brownie swirl pattern.
- Use room temperature ingredients for better mixing and consistency.
- These cookies freeze well; store in an airtight container for up to one month.
- For a crunchier texture, bake an additional 1-2 minutes, but be careful not to overbake.
