Step‑by‑Step Instructions for Peanut Butter Brownie Swirl Cookies
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). This ensures that it reaches the perfect temperature while you prepare the cookie dough. Prepare your baking sheets by lining them with parchment paper to prevent the cookies from sticking.
Step 2: Mix Wet Ingredients
In a large mixing bowl, cream together ½ cup of softened butter, ½ cup of granulated sugar, and ½ cup of brown sugar until the mixture is light and fluffy, which should take about 2-3 minutes. Then, blend in ½ cup of peanut butter and 1 teaspoon of vanilla extract until smooth, creating a rich base for your Peanut Butter Brownie Swirl Cookies.
Step 3: Add Egg
Next, add 1 large egg to your wet ingredients. Beat it in until it’s thoroughly incorporated, mixing well to ensure everything is combined. This egg not only binds the mixture but adds moisture, making the cookies irresistibly chewy.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together 1 cup of all-purpose flour, ⅓ cup of cocoa powder, ½ teaspoon of baking soda, ½ teaspoon of baking powder, and ¼ teaspoon of salt. This step is crucial for evenly distributing the leavening agents, ensuring your Peanut Butter Brownie Swirl Cookies rise beautifully in the oven.
Step 5: Mix Together
Gently fold the dry ingredients into the wet mixture gradually, stirring until just combined. Be careful not to over-mix, as this can make the cookies tough. As you blend, you will see the rich chocolate and creamy peanut butter flavors coming together. Lastly, fold in ½ cup of chocolate chips for that decadent touch.
Step 6: Chill Dough
If your dough feels too soft, refrigerate it for 10-15 minutes. This optional step helps firm up the dough, making it easier to shape and ensuring that your Peanut Butter Brownie Swirl Cookies hold their form while baking.
Step 7: Shape Cookies
Using a tablespoon or cookie scoop, drop rounded portions of dough onto your prepared baking sheets, leaving enough space between each to allow for spreading. If you’d like, you can create swirls by reserving a small amount of brownie dough and marbling it into the peanut butter dough just before baking.
Step 8: Bake
Place the baking sheets into the preheated oven and bake for 10-12 minutes, until the edges of the cookies are set, but the centers still appear slightly soft. This will ensure that they remain chewy once cooled, delivering the desired texture of Peanut Butter Brownie Swirl Cookies.
Step 9: Cooling
Once baked, allow the cookies to cool on the baking sheet for about 5 minutes. During this time, they will continue to firm up. Afterward, transfer the cookies to wire racks to cool completely, allowing their flavors to develop further.

Expert Tips for Peanut Butter Brownie Swirl Cookies
- Temperature Matters: Ensure your butter is softened but not melted. This will help achieve the perfect cookie texture without compromising richness.
- Don’t Over-Mix: Mix the dry ingredients into the wet until just combined. Over-mixing can lead to tough cookies, ruining your Peanut Butter Brownie Swirl Cookies’ chewy nature.
- The Perfect Swirl: For an eye-catching presentation, reserve some brownie dough and swirl it into the peanut butter dough right before baking to create stunning marbled cookies.
- Watch the Timer: Check your cookies a minute or two before the baking time ends. They should look soft but will firm up as they cool, ensuring a delightfully chewy center.
- Chill If Needed: If your dough feels overly soft and sticky, refrigerate it for 10-15 minutes. This makes shaping dough easier and keeps cookies from spreading too much while baking.
- Experiment with Add-Ins: Consider adding chopped nuts or a dash of cinnamon for extra flavor burst, allowing for personal touches to your Peanut Butter Brownie Swirl Cookies.

Peanut Butter Brownie Swirl Cookies Recipe FAQs
What kind of peanut butter is best for this recipe?
I recommend using creamy peanut butter for a smooth and luscious texture in your cookies. If you love a bit of crunch, go for crunchy peanut butter to add delightful bits throughout. Just make sure it’s not labeled as “natural” unless you have a specific preference, as those can have different consistencies that may affect the final outcome.
How should I store leftovers of Peanut Butter Brownie Swirl Cookies?
Absolutely! Store your cookies in an airtight container at room temperature for up to 1 week. If you want them to last a bit longer, you can refrigerate them for up to 2 weeks. Just remember to bring them back to room temperature or warm them in the microwave for a few seconds before enjoying for that fresh-baked texture!
Can I freeze the cookie dough for future baking?
Yes, you can! To freeze the dough, scoop rounded tablespoons of uncooked cookie dough onto a baking sheet lined with parchment paper and place it in the freezer until solid. Once frozen, transfer the dough balls into a freezer-safe bag, sealing it tightly. They can be stored in the freezer for up to 3 months. When you’re ready to bake, no need to thaw—just add a couple of extra minutes to the baking time.
What should I do if my cookies spread too much while baking?
If your cookies spread more than expected, don’t worry! This can often happen if the dough is too warm. In the future, try chilling the dough for 10-15 minutes before baking, as this helps keep their shape. Also, ensure your oven is preheated correctly and that you’re using a proper oven thermometer if necessary. And always remember, soft cookies will firm up as they cool!
Can my dog eat these cookies?
While your furry friend might look at you with those adorable puppy eyes, it’s best to keep these cookies away from pets. The primary ingredients, like sugar and chocolate, aren’t healthy for dogs. If you want to treat your pup, consider making specially formulated dog-friendly cookies that are safe for their digestion.
Does any ingredient need to be at room temperature?
Yes! It’s best to have your butter and egg at room temperature before you start mixing your ingredients. This helps them blend more smoothly into the dough, ensuring your Peanut Butter Brownie Swirl Cookies turn out soft and chewy, just as they should!
