Step‑by‑Step Instructions for Peanut Butter Brownie Swirl Cookies
Step 1: Make the Peanut Butter Dough
In a large mixing bowl, beat together the creamy peanut butter, softened butter, and brown sugar until light and fluffy, about 2-3 minutes. Add in one egg and a splash of vanilla extract, mixing until combined. You’ll want a smooth, creamy dough that looks inviting—this is the heart of your Peanut Butter Brownie Swirl Cookies!
Step 2: Combine the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and a pinch of salt. Gradually add this dry mixture to the wet peanut butter mixture, mixing until just combined. Take caution not to overmix; you should see no dry flour streaks. Your dough will be thick and ready to join its chocolatey counterpart soon!
Step 3: Prepare the Brownie Dough
In another bowl, combine the melted butter and white sugar, whisking until smooth. Stir in cocoa powder, the remaining egg, and vanilla extract. Ensure the mixture is glossy and well-blended; this silky brownie batter is the perfect complement to your peanut butter dough, creating the indulgent Peanut Butter Brownie Swirl Cookies!
Step 4: Add the Chocolatey Goodness
Next, gently fold in the flour, baking powder, salt, and chocolate chips into the brownie mixture. Mix until no dry ingredients remain visible. The brownie batter should be thick and rich, full of chocolatey goodness. This luscious batter will create a beautiful swirl when combined with the peanut butter dough.
Step 5: Chill the Doughs
Cover both doughs and chill them in the refrigerator for about 30 minutes. This step helps in firming up the dough, making it easier to scoop and swirl. You’ll know they’re ready when they are slightly hardened yet still easy to work with—just the right texture for crafting your gorgeous cookies!
Step 6: Scoop and Swirl the Doughs
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Using a cookie scoop or tablespoon, portion out 1-2 tablespoons of each dough, placing them side by side on the baking sheet. With a toothpick, gently swirl the two doughs together for a marbled effect that enhances the visual appeal of your Peanut Butter Brownie Swirl Cookies.
Step 7: Bake to Perfection
Bake the cookies in the preheated oven for 9-11 minutes. Watch for the tops to become crackly, while the edges set but the centers remain soft. This balance is essential for the perfect chewiness that these delightful cookies offer. Your kitchen will soon fill with the irresistible aroma of chocolate and peanut butter!
Step 8: Cool and Set
Once baked, let the cookies cool on the baking sheet for 5-10 minutes before transferring them to a wire rack to cool completely. Allowing them to rest helps them achieve the perfect texture—chewy on the inside with a light crisp on the outside. Get ready to share, as these Peanut Butter Brownie Swirl Cookies will surely disappear fast!

Peanut Butter Brownie Swirl Cookies Recipe FAQs
What is the best way to select ripe ingredients for these cookies?
For the best flavor and texture, use fresh, creamy peanut butter that is free from additives; it should be smooth and easy to spread. When selecting eggs, make sure they are fresh by checking the expiration date on the carton—an egg within a week of baking is ideal. The butter should be softened but not melted, so it blends easily into the dough.
How should I store Peanut Butter Brownie Swirl Cookies?
Store these cookies in an airtight container at room temperature for up to 7 days for maximum freshness. If you’d like to refrigerate them for a firmer texture, they can last up to 10 days when stored properly. The key is to ensure they are sealed well to prevent them from drying out!
Can I freeze Peanut Butter Brownie Swirl Cookies?
Absolutely! You can freeze these cookies for up to 2 months. To do this, let them cool completely, then wrap each cookie tightly in plastic wrap or place them in a freezer-safe bag. When you’re ready to enjoy, just thaw them at room temperature or reheat in the microwave for about 10-15 seconds for that fresh-baked taste!
What should I do if my dough is too soft to swirl?
If you find that your dough is too soft, it’s likely due to the butter being too warm or not chilling the dough long enough. To fix this, simply chill the dough for an additional 15-30 minutes in the refrigerator until it firms up. Alternatively, you can add a couple more tablespoons of flour to reach the desired consistency. Be gentle when swirling to maintain that beautiful marbled effect!
Are there any dietary considerations for pets or allergies?
Yes! Keep in mind that chocolate and peanuts are toxic to pets, so keep these cookies out of their reach. If you have allergies, consider making substitutions such as using sunflower seed butter instead of peanut butter for nut allergies. Always check ingredient labels, particularly for added sugars or allergens in chocolate chips as well.
Can I make these cookies vegan?
Certainly! To make your Peanut Butter Brownie Swirl Cookies vegan, substitute the regular butter with vegan butter and replace the egg with a flax egg (1 tablespoon of ground flaxseed mixed with 3 tablespoons of water, let sit for 5 minutes until it thickens). You can also use dairy-free chocolate chips to keep them completely plant-based. Enjoy baking!
