- 1 egg: Acts as the binder, giving structure and a chewy texture to the cookies.
- 1/2 cup cocoa powder: Adds deep chocolate flavor while keeping the batter moist and fudgy.
- 1 teaspoon vanilla extract: Enhances the overall taste and adds a subtle aromatic note.
- 1/2 teaspoon baking soda: Leavens the dough gently, ensuring the cookies aren’t dense.

How to Make Peanut Butter Brownie Swirl Cookies Recipe
Step 1: Preheat the Oven
Start by heating your oven to 350 degrees Fahrenheit (175 degrees Celsius). This ensures that when the cookies hit the tray, they bake evenly and develop that perfect slightly crisp edge with a soft center.
Step 2: Mix Peanut Butter, Sugar, and Egg
In a large mixing bowl, combine peanut butter, sugar, and egg. Mix thoroughly until the texture is smooth and glossy—this creates the foundation for a moist and flavorful cookie base.
Step 3: Add Cocoa Powder, Vanilla, Baking Soda, and Salt
Next, incorporate the cocoa powder, vanilla extract, baking soda, and salt. Stir just until everything is combined, being careful not to overmix so the cookies stay tender and perfectly fudgy.
Step 4: Fold in Chocolate Chips
Gently fold the chocolate chips into the dough, distributing them evenly throughout. These little pockets of chocolate will add bursts of melting richness in every bite.
Step 5: Portion the Dough
Drop tablespoon-sized dollops of cookie dough onto a baking sheet lined with parchment paper. Make sure to leave some space between each dough ball so they have room to spread without merging into each other.
Step 6: Create the Swirled Effect
Use a toothpick or the tip of a knife to swirl the dough on each cookie. This step creates the iconic brownie and peanut butter marbled look, making each cookie a unique little masterpiece.
Step 7: Bake to Perfection
Bake your cookies in the preheated oven for 10 to 12 minutes. Keep a close eye for when the edges look firm and set while the centers remain soft—this is the sweet spot for that perfect cookie texture.
Step 8: Cool and Transfer
Let the cookies cool on the baking sheet for a few minutes to set further, then gently move them to a wire rack to cool completely. This step helps maintain their structure and enhances the chewiness.
How to Serve Peanut Butter Brownie Swirl Cookies Recipe
Garnishes
For an elegant touch, sprinkle a pinch of flaky sea salt on top of the cookies before serving to enhance the peanut butter and chocolate flavors. Alternatively, dust them lightly with powdered sugar for a festive look and a hint of sweetness.
Side Dishes
Pair these cookies with a tall glass of cold milk or a warm cup of coffee or hot chocolate to complement their rich, indulgent taste. A scoop of vanilla ice cream on the side can elevate them to a mouthwatering dessert experience.
Creative Ways to Present
Arrange the cookies on a pretty platter layered with parchment paper and fresh mint leaves for a gorgeous presentation when guests arrive. You can also sandwich softened cream cheese frosting between two cookies for an indulgent twist everyone will adore.
Make Ahead and Storage
Storing Leftovers
Keep any leftover cookies in an airtight container at room temperature for up to four days. This helps the cookies stay soft and chewy without drying out, so they’re just as heavenly the next day.
Freezing
If you want to enjoy these treats later, freeze the baked cookies in a single layer on a baking sheet first, then transfer them to a freezer-safe container or bag. They’ll keep deliciously fresh for up to three months and thaw quickly when you’re ready to indulge.
Reheating
To revive the warm, gooey texture, pop the cookies in the microwave for 10 to 15 seconds or briefly heat them in the oven at 300 degrees Fahrenheit. It’s like biting into a fresh batch all over again.
FAQs
Can I use natural peanut butter for this recipe?
Absolutely! Natural peanut butter works well, though it might make the dough slightly less creamy. If it’s very runny, you might want to chill the dough briefly before baking to help maintain cookie shape.
Do I need to refrigerate the dough before baking?
Refrigeration is not necessary for this recipe since the dough has sturdy peanut butter and sugar. However, if your kitchen is warm, chilling the dough for 10-15 minutes can make portioning easier.
Can I substitute chocolate chips with chunks or nuts?
Yes! You can swap chocolate chips for chocolate chunks for bigger melty spots, or add chopped nuts like peanuts or walnuts for extra crunch and flavor contrast.
Are these cookies gluten-free?
Since this recipe contains no wheat-based flour, it is naturally gluten-free as long as your cocoa powder and other ingredients have no gluten cross-contamination.
What makes these cookies different from regular peanut butter cookies?
The addition of cocoa powder and the beautiful chocolate swirl create a luscious brownie element that transforms classic peanut butter cookies into a decadent hybrid worthy of dessert lovers.
