Step‑by‑Step Instructions for Peanut Butter Brownie Swirl Cookies
Step 1: Prepare Peanut Butter Dough
In a mixing bowl, beat 1 cup of creamy peanut butter, ½ cup softened butter, and 1 cup brown sugar together until the mixture is light and fluffy. Add in 1 egg and 1 teaspoon of vanilla extract, mixing until incorporated. In a separate bowl, whisk together 1 ½ cups of all-purpose flour, ½ teaspoon baking soda, and a pinch of salt before gradually combining with the wet ingredients until just incorporated.
Step 2: Prepare Brownie Dough
In another bowl, whisk ½ cup melted butter with 1 cup white sugar until smooth and creamy. Stir in ⅓ cup cocoa powder, 1 egg, and 1 teaspoon of vanilla extract. Gently fold in ½ cup flour, ½ teaspoon baking powder, ¼ teaspoon salt, and ½ cup chocolate chips until the brownie dough comes together without overmixing, ensuring the final layer of your Peanut Butter Brownie Swirl Cookies is fudgy.
Step 3: Chill Doughs
Cover both the peanut butter and brownie doughs with plastic wrap or store them in airtight containers. Place the doughs in the refrigerator for approximately 30 minutes to firm them up, making it easier to scoop and swirl later. This chilling step is crucial for achieving the perfect texture and swirls in your cookies.
Step 4: Shape Cookies
Once the doughs have chilled, preheat your oven to 350°F (175°C). On a parchment-lined baking sheet, scoop 1-2 tablespoons of both the peanut butter and brownie doughs, placing them side by side or slightly overlapping. Using a toothpick or skewer, gently swirl the two doughs together for that signature marbled look, creating beautiful Peanut Butter Brownie Swirl Cookies that will impress anyone.
Step 5: Bake
Transfer your lined baking sheet to the preheated oven and bake the cookies for 9-11 minutes. Keep an eye on them, as the tops should appear lightly crackly and the edges set while the centers may look a bit soft. This is the perfect visual cue that your cookies are done, ensuring that fudgy texture we love.
Step 6: Cool
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5-10 minutes. This cooling period helps them set while retaining their chewy texture. After they’re slightly cooled, transfer the Peanut Butter Brownie Swirl Cookies to a wire rack to cool completely before serving or enjoying yourself.

Make Ahead Options
These Peanut Butter Brownie Swirl Cookies are perfect for meal prep enthusiasts! You can prepare both the peanut butter and brownie doughs up to 3 days in advance.

This will help maintain their freshness and prevent drying out. When you’re ready to bake, allow the dough to soften for a few minutes at room temperature, then scoop and swirl as directed. You’ll have freshly baked cookies in no time, making weeknight dessert a breeze. Enjoy delicious, homemade treats with minimal effort!

Peanut Butter Brownie Swirl Cookies Recipe FAQs
How do I choose the right peanut butter for the dough?
Absolutely! When selecting peanut butter, look for creamy varieties without added sugars or hydrogenated oils to truly enhance your cookies. Natural peanut butter tends to have a smoother texture and pure flavor, making it my go-to choice. If you’re concerned about allergies, almond or sunflower seed butter can be excellent substitutes.
How should I store Peanut Butter Brownie Swirl Cookies?
To keep your cookies fresh and delicious, store them in an airtight container at room temperature for up to a week. If you want to extend their shelf life, I recommend refrigerating them for up to 2 weeks or freezing them for up to 3 months. Just be sure to use parchment paper between layers when freezing to prevent sticking.
Can I freeze the dough for later use?
Absolutely! You can freeze the dough before baking. Simply divide the chilled peanut butter and brownie dough into individual portions, wrap them tightly in plastic wrap, and place them in a freezer bag. This way, they’ll stay fresh for up to a month! When you’re ready to bake, just let the dough thaw in the refrigerator overnight before proceeding with baking as usual.
My cookies spread too much while baking. What did I do wrong?
Very! If your cookies spread too much, it could be due to several factors. First, make sure your butter is softened but not melted, as overly soft butter can lead to excess spreading. Also, chilling both doughs for at least 30 minutes is key to helping them maintain shape in the oven. Lastly, ensure you measure your flour correctly as too little can cause cookies to flatten.
Are these cookies safe for pets or individuals with allergies?
Please be cautious! Peanut butter can be harmful to pets, especially chocolate chips, which are toxic to dogs. If you’re serving these cookies to friends and family with dietary restrictions, it’s best to clearly label them if you use common allergens. Always opt for allergy-friendly ingredients when baking for someone with specific dietary needs or allergies to ensure a safe and enjoyable treat!
