Step‑by‑Step Instructions for Peanut Butter Brownie Swirl Cookies
Step 1: Prepare Peanut Butter Dough
In a mixing bowl, combine 1 cup of creamy peanut butter, ½ cup of softened, melted butter, and ¾ cup of brown sugar. Beat these together until the mixture is light and fluffy, about 2-3 minutes. Then, add in one egg and 1 teaspoon of vanilla extract, mixing until well incorporated. In a separate bowl, whisk together 1½ cups of flour, ½ teaspoon of baking soda, and a pinch of salt, then gradually mix this dry blend into your 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. Mix in ½ cup of cocoa powder, then add an egg and 1 teaspoon of vanilla extract, stirring until homogenous. Next, fold in ½ cup of all-purpose flour, ¼ teaspoon of baking powder, and a pinch of salt until just combined. The thickness of your brownie dough should be fudgy, providing that rich brownie base for the Peanut Butter Brownie Swirl Cookies.
Step 3: Chill Doughs
Cover both cookie doughs with plastic wrap and refrigerate them for about 30 minutes. Chilling is essential as it helps solidify the dough, making it easier to scoop and swirl together. As you wait, prepare your baking sheet by lining it with parchment paper to prevent sticking and to facilitate an easy cleanup.
Step 4: Form Cookies
After chilling, use a cookie scoop or tablespoon to scoop 1-2 tablespoons of each dough, placing them side by side on your prepared baking sheet. Aim for a neat arrangement, allowing some space between each cookie. Then, gently swirl the two doughs together using a toothpick or skewer to create a marbled effect, ensuring the swirls are distinct and the two flavors remain visible.
Step 5: Bake
Preheat your oven to 350°F (175°C). Once ready, bake the Peanut Butter Brownie Swirl Cookies in the oven for 9-11 minutes. You’ll know they’re done when the tops appear crackly and the edges are just set. Avoid overbaking to maintain that soft, chewy texture in the center that defines these delightful cookies.
Step 6: Cool
After baking, remove the cookies from the oven and allow them to cool on the baking sheet for 5-10 minutes. This resting period helps firm them up for easy handling. Afterward, use a spatula to transfer the cookies to a wire rack to cool completely. Enjoy watching as the colors and swirls of your Peanut Butter Brownie Swirl Cookies come to life!

How to Store and Freeze Peanut Butter Brownie Swirl Cookies
Room Temperature: Store cookies in an airtight container at room temperature for up to 1 week to keep them soft and chewy.
Fridge: If you prefer a chilled treat, you can also keep them in the fridge for up to 2 weeks. Just ensure they are well-wrapped to prevent drying out.

Reheating: To enjoy a fresh-baked taste, reheat the cookies in the oven at 350°F for about 5 minutes. This revives their soft texture, making your Peanut Butter Brownie Swirl Cookies irresistible!

Expert Tips for Peanut Butter Brownie Swirl Cookies
-
Dough Consistency: Ensure both doughs are similarly thick for easier swirling. This helps achieve those beautiful marbled effects that make your Peanut Butter Brownie Swirl Cookies visually appealing.

Uniform Sizes: Use a cookie scoop for consistent size. This ensures even baking, preventing some cookies from being overdone while others remain undercooked.
-
Swirling Technique: Don’t overmix when creating the swirls. Maintain distinct layers for the best flavor and visual impact—too much mixing can muddle the two delicious flavors.
-
Baking Time Watch: Keep an eye on the cookies towards the end of the baking time. Look for crackly tops with slightly soft centers to achieve that perfect, gooey texture.
-
Cooling Patience: Allow the cookies to cool properly on the baking sheet before transferring them. This step is crucial for maintaining their soft, chewy texture.

Peanut Butter Brownie Swirl Cookies Recipe FAQs
How do I select the best peanut butter for the recipe?
Absolutely! It’s best to choose a creamy, unsweetened peanut butter for these cookies. This type provides the rich, nutty flavor you’re looking for and blends well with the other ingredients, ensuring a smoother dough. Avoid natural varieties that separate, as they can alter the texture of your cookies.
How should I store leftover cookies?
Very good question! Store the Peanut Butter Brownie Swirl Cookies in an airtight container at room temperature for up to 1 week. If you want to keep them even longer, place them in the fridge for up to 2 weeks—just make sure they’re well-wrapped to keep them from drying out.
Can I freeze these cookies?
Of course! To freeze, arrange the cookies in a single layer on a baking sheet and place them in the freezer until solid, about 1-2 hours. Then, transfer them to an airtight container or freezer bag. They can be frozen for up to 3 months. When you’re ready to enjoy, simply reheat them in the oven at 350°F for about 5 minutes to restore their gooey texture.
What if my dough is too sticky or too dry?
Great observation! If your peanut butter dough is too sticky, you can sprinkle a bit more flour, a tablespoon at a time, until it reaches the right consistency. Conversely, if it’s too dry, a small splash of milk or a tablespoon of melted butter can help moisten it. Always aim for a thick yet scoopable dough that holds its shape.
Are there any dietary considerations I should keep in mind?
For sure! If you’re making these cookies for someone with allergies, ensure to use gluten-free flour for a gluten-free option and try using dairy-free butter and chocolate for a dairy-free treat. For vegans, replace the egg with a flax egg (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water) or chickpea water, plus ensure all other ingredients are plant-based.
