Ingredients:
For the Peanut Butter Dough:
- 1/2 cup creamy peanut butter
- 1/4 cup (1/2 stick) unsalted butter, softened
- 1/2 cup packed light brown sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
For the Brownie Dough:
- 1/2 cup (1 stick) unsalted butter, melted
- 1 cup granulated sugar
- 1/3 cup unsweetened cocoa powder
- 1 large egg
- 1 teaspoon vanilla extract
- 3/4 cup all-purpose flour
- 1/4 teaspoon baking powder
- 1/4 teaspoon salt
- 1/2 cup chocolate chips (semi-sweet or dark)

Preparation:
Step 1: Make the Peanut Butter Dough:
In a medium-sized mixing bowl, combine the softened peanut butter, butter, and brown sugar. Use an electric mixer (handheld or stand mixer) to beat the ingredients together until the mixture is light and fluffy. This typically takes about 2-3 minutes on medium speed. Be sure to scrape down the sides of the bowl occasionally to ensure all ingredients are evenly incorporated. Add the egg and vanilla extract to the peanut butter mixture. Continue to beat until well combined, about 1 minute.
In a separate, smaller bowl, whisk together the all-purpose flour, baking soda, and salt. Whisking ensures that the baking soda and salt are evenly distributed throughout the flour, which is essential for proper leavening and flavor balance in the cookies. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix, as this can result in tough cookies. Stop mixing as soon as the flour is incorporated and the dough is uniform.
Step 2: Make the Brownie Dough:
In a separate medium-sized mixing bowl, whisk together the melted butter and granulated sugar until well combined. Ensure that the sugar is fully incorporated into the melted butter, creating a smooth and consistent mixture. Add the cocoa powder to the butter and sugar mixture and beat until smooth and well combined. This step is crucial for developing the rich, chocolatey flavor of the brownie dough. Scrape down the sides of the bowl as needed.
Beat in the egg and vanilla extract until fully incorporated. Fold in the all-purpose flour, baking powder, and salt. Mix until no dry streaks remain. Do not overmix. Then, gently fold in the chocolate chips until they are evenly distributed throughout the brownie dough.
Step 3: Chill the Doughs:
Cover both the peanut butter dough and the brownie dough with plastic wrap, pressing the wrap directly onto the surface of each dough to prevent a skin from forming. Place both bowls in the refrigerator and chill for at least 30 minutes. Chilling the dough is essential for preventing the cookies from spreading too much during baking. It also helps to develop the flavors and make the dough easier to handle.
Step 4: Shape and Swirl the Cookies:
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper. This prevents the cookies from sticking and makes for easy cleanup.
Scoop 1-2 tablespoon portions of each dough. Roll each portion of dough into a ball. Place the peanut butter dough ball and the brownie dough ball side by side on the prepared baking sheet, leaving about 2 inches of space between each pair of dough balls. Repeat this process until all of the dough is used.
Use a toothpick or a thin skewer to gently swirl the doughs together in a marble pattern. Be careful not to overmix the doughs, as this can muddy the colors and lose the distinctive swirl effect. Aim for a visually appealing, marbled effect with distinct swirls of peanut butter and brownie dough.
Step 5: Bake and Cool:
Bake in the preheated oven for 9-11 minutes, or until the tops are lightly crackly and the edges are just set. The centers will still be quite soft, which is what gives these cookies their chewy texture.
Allow the cookies to cool on the baking sheet for 5-10 minutes before transferring them to a wire rack to cool completely. This allows the cookies to set up slightly and prevents them from breaking when you move them.

Questions and Answers about this Recipe:
Q1: Can I use natural peanut butter for this recipe?
A: Yes, you can use natural peanut butter, but be aware that it may affect the texture of the cookies. Natural peanut butter tends to be oilier, so the dough might be slightly softer. You may need to add a tablespoon or two of extra flour to the peanut butter dough to compensate for the extra moisture. Also, be sure to stir the natural peanut butter well before measuring it to ensure the oil is evenly distributed.
Q2: Can I make these cookies ahead of time?
A: Absolutely! You can make the doughs ahead of time and store them in the refrigerator for up to 2 days. Just be sure to wrap them tightly in plastic wrap. You can also freeze the dough balls after shaping them. Place them on a baking sheet lined with parchment paper and freeze until solid. Then, transfer them to a freezer-safe bag or container and store for up to 2 months. When ready to bake, simply bake the frozen dough balls directly from the freezer, adding a few extra minutes to the baking time.
Q3: What if I don’t have baking soda or baking powder? Can I still make these cookies?
A: Baking soda and baking powder are essential leavening agents that help the cookies rise and have a light, airy texture. If you don’t have baking soda, you can try using baking powder as a substitute, but it may not provide the same results. Use twice the amount of baking powder as the recipe calls for baking soda. If you don’t have baking powder, you can try using a mixture of cream of tartar and baking soda. However, it’s best to use the correct ingredients for the best results.
Q4: My cookies spread too much while baking. What did I do wrong?
A: Several factors can cause cookies to spread too much while baking. The most common reasons are:
- Dough wasn’t chilled enough: Chilling the dough is crucial for preventing spreading. Make sure to chill both doughs for at least 30 minutes.
- Oven temperature too low: An inaccurate oven temperature can cause the cookies to spread before they set. Use an oven thermometer to ensure your oven is properly heated.
- Too much butter or sugar: Too much fat or sugar in the dough can cause the cookies to spread. Make sure to measure the ingredients accurately.
- Overmixing the dough: Overmixing the dough can develop too much gluten, which can also cause spreading. Mix the doughs until just combined.
Q5: Can I add nuts to this recipe?
A: Yes, you can definitely add nuts to this recipe! Chopped peanuts, walnuts, or pecans would all be delicious additions. You can add about 1/2 cup of chopped nuts to either or both of the doughs. Gently fold them in after you’ve added the flour. For an extra toasty flavor, you can toast the nuts in a dry skillet or in the oven before adding them to the dough.
