Step‑by‑Step Instructions for Peanut Butter Brownie Swirl Cookies
Step 1: Prepare Peanut Butter Dough
In a mixing bowl, beat together ½ cup of creamy peanut butter, ¼ cup of softened butter, and ¾ cup of brown sugar until the mixture is light and fluffy, about 2-3 minutes. Then, incorporate one egg and a teaspoon of vanilla extract until well combined. In a separate bowl, whisk together 1¼ cups of all-purpose flour, ½ teaspoon of baking soda, and ¼ teaspoon of salt. Gradually mix the dry ingredients into the wet mixture, blending until just combined.
Step 2: Prepare Brownie Dough
In a different bowl, whisk together ¼ cup of melted butter and ½ cup of white sugar until smooth. Add in ¼ cup of unsweetened cocoa powder, one egg, and a teaspoon of vanilla extract, mixing until fully incorporated. Next, fold in ½ cup of all-purpose flour, ¼ teaspoon of baking powder, and a pinch of salt until no dry streaks remain. Finally, gently mix in ½ cup of chocolate chips for an extra burst of flavor.
Step 3: Chill Both Doughs
Cover both the peanut butter dough and brownie dough separately with plastic wrap and refrigerate for 30 minutes. Chilling helps firm up the dough, ensuring the cookies hold their shape and making it easier to create that delightful swirl in your Peanut Butter Brownie Swirl Cookies.
Step 4: Scoop and Swirl
Preheat your oven to 350°F (175°C) while the dough chills. Line a baking sheet with parchment paper. Using a cookie scoop or tablespoon, drop small portions of the peanut butter dough and brownie dough side by side on the prepared baking sheet. With a toothpick or skewer, gently swirl the two doughs together to create a marbled effect but be careful not to overmix.
Step 5: Bake
Place the baking sheet in your preheated oven and bake the cookies for 9-11 minutes. Watch for tops to become crackly and edges to set while the centers remain soft and chewy to ensure the perfect texture for your Peanut Butter Brownie Swirl Cookies.
Step 6: Cool
Once baked, take the cookies out of the oven and allow them to cool on the baking sheet for 5-10 minutes. This cooling period allows them to firm up a bit before transferring them to a wire rack. Enjoy the incredible aroma as you prepare to savor these delightful cookies!

How to Store and Freeze Peanut Butter Brownie Swirl Cookies
Room Temperature: Store cookies in an airtight container at room temperature for up to one week to maintain their soft texture and flavor.

Peanut Butter Brownie Swirl Cookies Recipe FAQs
How do I choose the right peanut butter?
Absolutely! For the best flavor and texture, opt for a creamy peanut butter without added sugars or hydrogenated oils. If you have nut allergies, you can substitute it with almond butter or sunbutter, which works beautifully in this recipe.
How should I store the cookies?
These delightful cookies can be stored in an airtight container at room temperature for up to one week. If you’d like to keep them for longer, I recommend refrigerating them, where they can last for up to two weeks. Just make sure to let them come back to room temperature before enjoying for the best taste!
Can I freeze Peanut Butter Brownie Swirl Cookies?
Yes, you can freeze these cookies for up to three months! To do this, first allow them to cool completely. Place them in a freezer-safe bag or an airtight container, separating layers with parchment paper to prevent sticking. When you’re ready to indulge, simply thaw at room temperature or microwave for a quick warm-up.
What if my doughs are too sticky or dry?
Very! If your peanut butter dough turns out too sticky, it’s usually due to too much moisture or peanut butter; consider adding a bit more flour gradually until the desired consistency is achieved. Conversely, if it’s too dry, it may need a splash of water or a bit more peanut butter. For the brownie dough, ensure both doughs have a similar texture for better swirling. If correctly balanced, they produce stunning cookies!
Are there any allergy considerations?
Absolutely! While these cookies are safe for most, those with nut allergies should avoid traditional peanut butter and consider using a seed-based butter like sunbutter. Also, be sure to check that your chocolate chips are dairy-free if you’re making these cookies dairy-free or vegan!
Can I substitute any ingredients for dietary needs?
Yes, indeed! For those needing gluten-free cookies, simply swap all-purpose flour for a gluten-free flour blend. For a dairy-free version, use dairy-free butter, and opt for non-dairy chocolate chips. And if you’re looking to make these cookies vegan, replace the egg with a flax egg or applesauce and ensure all other ingredients are vegan-friendly. Your options for deliciousness are limitless!
