For the Peanut Butter Dough
• Creamy Peanut Butter – Adds smoothness and that signature peanut flavor; almond butter is a great nut-free alternative.
• Softened Butter – Provides richness and moisture; ensure it’s at room temperature for the best texture.
• Brown Sugar – Contributes to chewiness and caramel notes; coconut sugar can be used for a refined sugar-free option.

• Vanilla Extract – Enhances all the flavors; opt for pure vanilla for the best taste.
• All-Purpose Flour – Offers structure; for gluten-free, substitute with a 1:1 gluten-free flour blend.

• Salt – Balances the sweetness and elevates the flavors. -
For the Brownie Dough
• Melted Butter – Works with cocoa to create a rich, fudgy brownie flavor.
• White Sugar – Sweetens the brownie component; a natural sweetener or sugar substitute can work here as well.
• Cocoa Powder – Gives the brownie its chocolate depth; always use unsweetened for the best results.
• Baking Powder – Adds additional leavening for the brownie texture.
• Chocolate Chips – Provides richness and texture; go for dairy-free chips if you’re following a vegan diet.

Step‑by‑Step Instructions for Peanut Butter Brownie Swirl Cookies
Step 1: Prepare Peanut Butter Dough
In a large mixing bowl, beat together 1 cup of creamy peanut butter, 1/2 cup softened butter, and 1 cup of brown sugar until the mixture becomes fluffy and well combined, about 2-3 minutes. Add in one egg and 1 teaspoon vanilla extract, mixing until smooth. Gradually incorporate 1 ½ cups all-purpose flour, 1 teaspoon baking soda, and 1/4 teaspoon salt, ensuring everything is mixed thoroughly without overmixing.
Step 2: Prepare Brownie Dough
In a separate bowl, whisk together 1/2 cup melted butter and 1 cup white sugar until smooth. Stir in 1/2 cup unsweetened cocoa powder, followed by one egg and 1 teaspoon vanilla extract. Carefully fold in 1/2 cup all-purpose flour, 1/2 teaspoon baking powder, 1/4 teaspoon salt, and 1 cup chocolate chips, mixing just until combined to maintain the brownies’ fudgy texture.
Step 3: Chill Doughs
Cover both the peanut butter and brownie doughs separately with plastic wrap and place them in the refrigerator for 30 minutes, allowing the doughs to firm up slightly. Chilling is key for easier handling and ensures that your Peanut Butter Brownie Swirl Cookies maintain their shape while baking, giving them that perfect, chewy center.
Step 4: Scoop and Swirl
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Using a cookie scoop, scoop tablespoon-sized balls of the peanut butter and brownie dough, placing them side by side on the prepared baking sheet. Using a toothpick or a knife, gently swirl the doughs together to create a marbled effect, being careful not to over-mix.
Step 5: Bake
Transfer the baking sheet to the preheated oven and bake your Peanut Butter Brownie Swirl Cookies for 9-11 minutes, or until the tops appear crackly and the edges are set while the centers remain soft. Keep an eye on them—overbaking will lead to less chewy cookies, so remove them when they look just right.
Step 6: Cool
Allow the cookies to cool on the baking sheet for about 5-10 minutes, letting them set before transferring them to a cooling rack. This resting period is essential as it allows the cookies to finish baking from residual heat, ensuring a deliciously gooey center in your Peanut Butter Brownie Swirl Cookies.

Make Ahead Options
These Peanut Butter Brownie Swirl Cookies are perfect for meal prep lovers! You can prepare both the peanut butter and brownie doughs up to 24 hours in advance; simply store each separately in airtight containers after chilling them for 30 minutes. To maintain their delightful texture, make sure to refrigerate the doughs well-wrapped to prevent drying out. When you’re ready to bake, let the dough sit at room temperature for about 10 minutes before scooping and swirling them on the baking sheet. This way, you’ll enjoy that gooey, chewy goodness without any hassle on busy days!

Expert Tips for Peanut Butter Brownie Swirl Cookies
-
Consistency is Key: Ensure both doughs have a similar consistency for easier swirling. If one is too dry or crumbly, adjust with a touch more butter or a splash of milk.
-
Gentle Swirling: Avoid overmixing when swirling to maintain the beautiful marbled effect. A light touch with a toothpick is all you need!
-
Uniform Size: Use a cookie scoop to portion out the dough. This guarantees even baking and ensures that each Peanut Butter Brownie Swirl Cookie bakes perfectly.
-
Chill for Best Results: If the dough is too firm to swirl easily, chill each dough batch separately. This helps with rolling and creates a nice chewy cookie.
-
Watch the Oven: Keep an eye on the baking time—the centers should remain soft while the edges set. Overbaking will result in cookies that aren’t as pleasantly chewy!
