Ingredients
For the Peanut Butter Cookie Dough:
Instructions
-
In a small saucepan over low heat, melt the butter and chocolate together until smooth, stirring frequently to avoid scorching. Remove from heat and let it cool for a few minutes. Whisk in the sugar, eggs, and vanilla until combined. Stir in the flour, cocoa powder, and salt, mixing just until no streaks remain. Set aside.
-
In a mixing bowl, beat together the softened butter, peanut butter, granulated sugar, and brown sugar until creamy and fluffy, about 2–3 minutes. Add the egg and vanilla extract, mixing until fully incorporated. Slowly blend in the flour, baking soda, and salt until a soft dough forms.
-
Now comes the fun part—the swirl! Using a small cookie scoop, take equal portions of peanut butter dough and brownie batter. Gently press them together and roll into a ball, being careful not to overmix. You want to see distinct swirls, not a fully blended dough. Place the dough balls on a parchment-lined baking sheet, spacing them about 2 inches apart.
-
Preheat the oven to 350°F (175°C). Bake the cookies for 10–12 minutes, or until the edges are set but the centers still look slightly soft. They’ll continue to firm up as they cool. Avoid overbaking, as this can dry out the brownie portion.
-
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack. Serve warm for maximum gooeyness, or let them cool completely for a more defined swirl pattern.

Peanut Butter Brownie Swirl Cookies – Tips, Tricks & Serving Ideas
Peanut Butter Brownie Swirl Cookies are the kind of indulgent treat that bring together the best of both worlds: the fudgy richness of brownies and the nutty creaminess of peanut butter cookies.
They’re a little dramatic to look at with their marbled swirl patterns, and even more satisfying to bite into thanks to their chewy-meets-soft texture. To make yours truly stand out, here are some smart tips, tricks, and serving ideas that will help you get bakery-quality results every time.
Baking Tips & Tricks
- Use Room Temperature Ingredients
For both the peanut butter dough and the brownie batter, having ingredients at room temperature ensures smoother mixing. Butter, eggs, and cream cheese (if used in the brownie portion) should not be cold, as this helps the batters blend evenly. - Don’t Overmix the Doughs
One of the most common mistakes is overmixing, which can toughen cookies. Mix just until ingredients are combined—this keeps the brownie portion fudgy and the peanut butter portion tender. - Choose the Right Peanut Butter
A creamy, shelf-stable peanut butter (like Jif or Skippy) works best for structure. Natural peanut butters can cause the dough to spread too much and separate. If you love natural peanut butter flavor, try using half natural and half conventional. - Get the Swirl Right
To achieve that picture-perfect marbled look, scoop a bit of brownie dough and a bit of peanut butter dough side by side, then gently roll them together into a ball. Avoid fully blending them—less mixing equals more dramatic swirls after baking. - Chill Before Baking
Chill your dough balls for 20–30 minutes in the refrigerator before baking. This prevents excess spreading, helping the cookies stay thick and chewy. - Bake on Parchment or Silicone Mats
Lining your baking sheets ensures cookies don’t stick and helps them bake evenly. Silicone mats are particularly great for maintaining chewy centers. - Watch the Bake Time
These cookies are best slightly underbaked in the center—they’ll continue to set on the hot pan after being removed from the oven. Overbaking can cause them to lose their gooey texture. - Add Mix-Ins for Flair
Consider adding chocolate chips, peanut butter chips, or even chopped Reese’s cups into the dough. This intensifies the flavor and makes the cookies extra decadent.
Serving Suggestions
- Warm with Ice Cream
Freshly baked Peanut Butter Brownie Swirl Cookies pair beautifully with a scoop of vanilla or peanut butter ice cream. The contrast of warm and cold makes for a restaurant-worthy dessert. - Drizzle & Dip
Elevate your cookies by drizzling melted chocolate or caramel sauce on top. For a fun party platter, serve them with small bowls of melted peanut butter, fudge sauce, or even a cream cheese dip. - Cookie Sandwiches
Turn two cookies into a handheld dessert sandwich with a filling of vanilla frosting, peanut butter buttercream, or even marshmallow fluff. - Holiday Treats
These cookies make a stunning addition to a Christmas, Valentine’s, or Easter cookie platter because of their eye-catching swirls. Wrap them in cellophane bags with ribbon for homemade gifts. - Coffee or Milk Pairing
Nothing beats dunking one of these cookies into a cold glass of milk or a hot cup of coffee. The rich chocolate and nutty peanut butter balance both beverages perfectly.
Tips for Perfect Swirl Cookies
- Use room temperature ingredients: This ensures even mixing and better texture.
- Chill the dough (optional): If your kitchen is warm, chilling the dough balls for 20 minutes before baking helps maintain the swirl design.
- Don’t over-swirl: Gently combining the doughs keeps the marbled look distinct.
- Storage: Store cookies in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months.
Variations to Try
- Double Chocolate Swirl: Add white chocolate chips to the peanut butter side for contrast.
- Nutty Crunch: Fold chopped peanuts or pecans into the brownie batter.
- Salted Caramel Drizzle: After cooling, drizzle warm caramel and sprinkle with flaky sea salt.
- Holiday Twist: Use red and green sprinkles in the peanut butter dough for a festive look.

Frequently Asked Questions
Can I use boxed brownie mix for the swirl instead of making it from scratch?
Yes! A boxed brownie mix works wonderfully and saves time. Simply prepare the brownie batter according to the package instructions (using eggs, oil, and water as directed), then swirl it into your peanut butter cookie dough. The texture will still be rich and fudgy, though homemade brownie batter tends to yield a more decadent flavor.
How do I achieve the perfect swirl effect without overmixing?
To create that signature marbled look, drop spoonfuls of both doughs side by side onto your baking sheet. Then, use a butter knife or toothpick to gently swirl the batters together with a light hand. Avoid overmixing, as it can blend the two doughs completely, losing the visual contrast and distinct flavor layers.
How should I store Peanut Butter Brownie Swirl Cookies, and how long do they stay fresh?
These cookies can be stored in an airtight container at room temperature for 3–4 days. If you’d like them to last longer, refrigerate for up to one week or freeze for up to two months. To enjoy later, simply thaw at room temperature or warm slightly in the microwave for a soft, gooey bite.
Can I customize this recipe with add-ins?
Absolutely! These cookies are versatile. You can add chocolate chips for extra richness, chopped peanuts for crunch, or even drizzle melted peanut butter or chocolate on top after baking. For a fun twist, try using flavored peanut butter (like honey roasted or chocolate peanut butter) to change up the flavor profile.
