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, ½ cup softened butter, and 1 cup of brown sugar until the mixture is light and fluffy—this should take about 2-3 minutes. Gradually mix in 1 egg and 1 teaspoon of vanilla extract until combined. In a separate bowl, whisk together 1¼ cups of all-purpose flour, 1 teaspoon of baking soda, and a pinch of salt; then gradually blend this dry mixture into the wet ingredients until just combined.
Step 2: Prepare Brownie Dough
In another bowl, whisk ½ cup of melted butter with 1 cup of white sugar until smooth. Add in ⅓ cup of cocoa powder, 1 egg, and 1 teaspoon of vanilla. Mix well until all are combined. Now, fold in ½ cup of flour, ½ teaspoon of baking powder, and a pinch of salt, ensuring all dry ingredients are incorporated. Finally, stir in ½ cup of chocolate chips, creating a gooey, rich brownie dough.
Step 3: Chill Doughs
Cover both the peanut butter and brownie doughs with plastic wrap and refrigerate for about 30 minutes. This chilling step is essential as it firms up the doughs to prevent spreading during baking, ensuring your Peanut Butter Brownie Swirl Cookies maintain their shape and achieve that perfect texture.
Step 4: Form Cookies
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Using a cookie scoop, take 1-2 tablespoons of each dough and place them side by side on the lined baking sheet. With a toothpick or skewer, gently swirl the two doughs together—aim for a marbled appearance without overmixing to maintain the distinct brownie and peanut butter flavors.
Step 5: Bake
Carefully place the baking sheet in the preheated oven and bake the cookies for 9-11 minutes. You’ll know they are ready when the tops appear lightly crackled and the edges are just set—this visual cue is crucial for achieving that soft, chewy texture of the Peanut Butter Brownie Swirl Cookies.
Step 6: Cool
Once done, remove the cookies from the oven and let them cool on the baking sheet for 5-10 minutes. This allows them to firm up before transferring to a wire rack to cool completely. Enjoy the delightful aroma of peanut butter and chocolate wafting through your kitchen as you wait!

Peanut Butter Brownie Swirl Cookies Recipe FAQs
How do I choose ripe ingredients?
For the best flavor and texture, ensure your peanut butter is creamy and smooth—check for a fresh expiration date. When selecting eggs, go for ones with uncracked shells and a clean appearance. Room temperature butter ensures easy blending, which is key for achieving fluffy dough. For flour, look for a finely milled product; a good all-purpose or gluten-free blend can make a delicious difference.
How should I store leftover cookies?
Absolutely! Store your Peanut Butter Brownie Swirl Cookies in an airtight container at room temperature for up to 7 days. If you notice them starting to dry out, adding a slice of bread to the container can help maintain moisture. For longer storage, refrigerate them wrapped tightly for up to 2 weeks.
Can I freeze these cookies?
Yes, you can! To freeze your Peanut Butter Brownie Swirl Cookies, lay them in a single layer on a baking sheet and place them in the freezer until solid, about 1-2 hours. Then, transfer the cookies to a freezer-safe bag or container, ensuring to remove as much air as possible. They will stay fresh for up to 3 months. When ready to enjoy, simply thaw overnight in the fridge or warm them in the microwave for a delightful treat!
What should I do if the cookies spread too much while baking?
If you find your cookies spreading more than expected, it might be due to warm dough or not chilling it sufficiently. Ensure you chill the dough for at least 30 minutes in the refrigerator. Additionally, check that your baking soda is fresh; expired baking soda may not provide the necessary lift to keep cookies from spreading too thin.
Are there any allergy considerations for this recipe?
Absolutely! For those with peanut allergies, you can substitute creamy peanut butter with almond butter, sunflower seed butter, or another nut-free alternative. If you’re catering to gluten sensitivities, opt for a gluten-free flour blend to ensure all your guests can enjoy these cookies. Lastly, for a dairy-free option, select vegan butter and dairy-free chocolate chips, which are widely available now.
Can I make these cookies vegan?
