Peanut Butter Brownie Swirl Cookies are the ultimate indulgence for dessert lovers who can never decide between brownies and cookies. This recipe combines the chewy, fudgy richness of a brownie with the nutty, creamy goodness of peanut butter cookies, all in one irresistible treat. Each bite offers a delightful contrast: the deep chocolate intensity of a brownie swirled perfectly with the sweet, salty creaminess of peanut butter dough. Perfect for holidays, parties, or late-night cravings, Peanut Butter Brownie Swirl Cookies are proof that sometimes the best desserts come from blending two classics into one show-stopping treat.
Why Is This Peanut Butter Brownie Swirl Cookies Recipe So Popular?

And let’s not forget the visual appeal. The swirl pattern not only looks beautiful but also signals to anyone looking at them that these cookies are something special. They’re often the first to disappear at bake sales, cookie exchanges, or dessert buffets.

How to Make Peanut Butter Brownie Swirl Cookies:
Now that you have your ingredients ready, let’s dive into the steps for making these delightful Peanut Butter Brownie Swirl Cookies. It’s as easy as pie, and I promise you’ll feel like a culinary superstar!
Step 1: Preheat the oven
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.
Step 2: Prepare the brownie dough
In a medium bowl, whisk together the melted butter, sugar, eggs, and vanilla until smooth. Add the cocoa powder, flour, baking powder, and salt. Stir until just combined, being careful not to overmix. Set aside.
Step 3: Prepare the peanut butter dough
In a separate bowl, beat together softened butter, peanut butter, brown sugar, and granulated sugar until light and creamy. Add the egg and vanilla, mixing well. Slowly stir in the flour, baking soda, and salt until a soft dough forms.
Step 4: Combine the doughs
Take a spoonful of brownie dough and a spoonful of peanut butter dough. Press them gently together, then roll into a ball. Place the dough ball on your prepared baking sheet. Repeat until all dough is used.
Step 5: Swirl for effect
Use a toothpick or butter knife to lightly swirl the two doughs together on top of each cookie ball. This creates the marbled effect once baked.
Step 6: Add optional toppings
If using, press a few chocolate chips, chopped peanuts, or a mini peanut butter cup into the top of each cookie ball.
Step 7: Bake
Bake in the preheated oven for 10–12 minutes, or until edges are set but the centers are still slightly soft. The cookies will continue to firm up as they cool.
Step 8: Cool and enjoy
Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack. Enjoy warm for a gooey center or cooled for a firmer bite.
Tips for Success:
- Don’t Overbake – These cookies taste best when slightly underbaked, so they stay soft and chewy.
- Chill the Dough – If the dough feels sticky, chill it in the fridge for 15–20 minutes before shaping.
- Use Quality Cocoa – A high-quality cocoa powder makes the brownie dough richer and more flavorful.
- Consistency Matters – If one dough feels much softer than the other, refrigerate it briefly so both are easier to work with.
- Size Evenly – Use a cookie scoop for consistent-sized cookies that bake evenly.
Equipment Needed:
- Mixing bowls (2)
