Step‑by‑Step Instructions for Peanut Butter Brownie Swirl Cookies
Step 1: Prepare Cookie Dough
Begin by creaming together ½ cup of unsalted butter, ½ cup of granulated sugar, and ½ cup of brown sugar in a large mixing bowl. Use an electric mixer on medium speed for about 2-3 minutes until the mixture is light and fluffy. Then, add one large egg and 1 teaspoon of vanilla extract, mixing until fully combined and smooth.
Step 2: Mix Dry Ingredients
In a separate bowl, whisk together 1 cup of all-purpose flour, ¼ teaspoon of baking soda, ⅓ cup of cocoa powder, and ½ teaspoon of salt. Ensure these dry ingredients are well-combined to avoid clumping. This mixture is essential for the structure of your Peanut Butter Brownie Swirl Cookies.
Step 3: Combine Ingredients
Gradually add the dry mixture to the wet ingredients from Step 1. Mix on low speed until just combined, being careful not to overmix. Your dough should be thick and slightly sticky, hinting at the delicious blend of chocolate and peanut butter flavors that awaits you.
Step 4: Incorporate Peanut Butter
Gently swirl in ½ cup of creamy or crunchy peanut butter, using a spatula to create a marbled effect. Do not fully mix the peanut butter in; the goal is to have visible ribbons of peanut butter throughout the dough, which will create that lovely contrast in your Peanut Butter Brownie Swirl Cookies.
Step 5: Add Chocolate Chips
Fold in 1 cup of chocolate chips evenly throughout the dough, making sure they are well-distributed for melty chocolate goodness in every bite. The chocolate chips add an extra layer of indulgence to your cookies, enhancing the brownie-like texture.
Step 6: Chill Dough (Optional)
If your dough is too soft to handle, chill it in the refrigerator for about 30 minutes to firm it up. This step is optional but helps in shaping the cookies neatly and prevents them from spreading too much while baking.
Step 7: Preheat Oven
While the dough chills, preheat your oven to 350°F (175°C). This ensures your oven is ready to bake the cookies evenly, helping achieve that perfect chewy center while maintaining a slightly crisp edge.
Step 8: Shape Cookies
Using a cookie scoop or tablespoon, scoop the dough onto a baking sheet lined with parchment paper, placing them about 2 inches apart. This spacing allows the cookies to spread without merging into each other, creating those individual, beautifully swirled treats.
Step 9: Bake
Bake the cookies in the preheated oven for 12-15 minutes, until the edges are set but the centers remain soft. Remove from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. This cooling time is crucial for achieving that gooey texture inside!

Expert Tips for Peanut Butter Brownie Swirl Cookies
-
Chill the Dough: Refrigerate your dough for 10-15 minutes if too soft. This helps with easier handling and prevents excess spreading during baking.
-
Perfectly Underbaked: Aim for slightly underbaked cookies; they will continue to firm up while cooling, delivering the best chewy texture in your Peanut Butter Brownie Swirl Cookies.
-
Adjusting Sweetness: Feel free to reduce the sugar slightly for a less sweet cookie. Balancing flavors is essential, so taste your dough for sweetness!
-
Use Quality Ingredients: Opt for pure vanilla extract and high-quality cocoa powder for richer flavors. Slight differences can enhance your cookie’s overall taste.
-
Swirl Technique: Don’t over-mix the peanut butter into the dough. Gently swirling it creates beautiful marbled patterns and provides that delightful peanut butter surprise in every bite!
Make Ahead Options
These Peanut Butter Brownie Swirl Cookies are perfect for busy weeknights and meal prep enthusiasts! You can prepare the cookie dough up to 24 hours in advance; simply cover it tightly in plastic wrap and refrigerate to maintain freshness. Additionally, you can scoop out individual cookie dough balls and freeze them for up to 2 months—just freeze in a single layer, then transfer to a freezer bag. When you’re ready to bake, you can bake the frozen dough straight from the freezer, adding an extra 1-2 minutes to the baking time. This way, you’ll always have fresh cookies at a moment’s notice, delivering that same delicious taste without the hassle!
