Step‑by‑Step Instructions for Peanut Butter Brownie Swirl Cookies
Step 1: Make Peanut Butter Dough
In a mixing bowl, cream together 1 cup of creamy peanut butter, ½ cup softened butter, and 1 cup brown sugar until the mixture is light and fluffy, about 2-3 minutes. Then, beat in 1 egg and 1 teaspoon vanilla extract until fully combined. In a separate bowl, whisk together 1 ½ cups all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt before gradually mixing it into the wet ingredients until just combined.
Step 2: Make Brownie Dough
In another bowl, combine ½ cup melted butter and 1 cup white sugar, mixing until smooth. Then, stir in ⅓ cup cocoa powder until well blended. Beat in 1 egg and 1 teaspoon vanilla extract, followed by folding in ½ cup flour, ½ teaspoon baking powder, ¼ teaspoon salt, and 1 cup chocolate chips, ensuring everything is mixed until fully incorporated for the luscious brownie layer.
Step 3: Chill Doughs
Cover both doughs with plastic wrap or transfer them into airtight containers and refrigerate for 30 minutes. Chilling helps firm up the doughs, making them easier to scoop and swirl into cookies. This little waiting game is essential for achieving the perfect texture in your Peanut Butter Brownie Swirl Cookies.
Step 4: Form Cookies
After chilling, preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper. Scoop about 1 to 2 tablespoons of both doughs—peanut butter and brownie—onto the baking sheet, placing them side by side. With a toothpick or skewer, gently swirl the two doughs together to create a beautiful marbled effect, careful not to overmix.
Step 5: Bake
Slide the baking sheet into the preheated oven and bake the cookies for 9 to 11 minutes. You’ll know they’re ready when the tops are crackly and the edges appear set, while the centers remain slightly soft. The contrast between the fudgy brownie and creamy peanut butter will entice your senses!
Step 6: Cool
After baking, allow the cookies to cool on the baking sheet for 5 to 10 minutes. This will help them firm up a bit and make transferring easier. Once slightly cooled, use a spatula to transfer the cookies to a wire rack, where they can cool completely. This step is crucial for achieving the perfect texture of your delicious Peanut Butter Brownie Swirl Cookies!

Make Ahead Options
These Peanut Butter Brownie Swirl Cookies are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare both the peanut butter and brownie doughs up to 24 hours in advance. Simply follow the recipe steps until chilling, cover each dough tightly with plastic wrap, and refrigerate. When you’re ready to bake, scoop and swirl the chilled doughs as if you had just made them. This prep ensures your cookies turn out just as delicious, maintaining that soft texture and rich flavor we all adore. Enjoy these tasty treats fresh from the oven with minimal effort, making your busy weeknights a little sweeter!

Peanut Butter Brownie Swirl Cookies Recipe FAQs
How do I select the right peanut butter?
Absolutely! For the best flavor and texture, choose a creamy, natural peanut butter that contains just peanuts and salt. This will ensure your cookies are nutty and delightful. Look out for any brands that might have added sugar, which can alter the final outcome.
What’s the best way to store these cookies?
Keep your Peanut Butter Brownie Swirl Cookies in an airtight container at room temperature for up to 5 days. If you want to extend their life, refrigerate them for up to a week. Just ensure they’re covered, so they don’t dry out—no one wants a sad, crumbly cookie!
Can I freeze these cookies?
Absolutely! To freeze your cookies, place them in a single layer on a baking sheet first, allowing them to freeze completely. Then transfer them into a freezer-safe bag or container. They can last up to 3 months! When you’re ready to enjoy, simply pop them in the microwave for 10-15 seconds for that fresh-out-of-the-oven warmth.
What can I do if the dough is too firm?
Very! If you notice that either dough is too firm, you can simply add a tablespoon or two of softened butter or a splash of milk. Mix it in and let it rest a bit before trying again. This small adjustment can make all the difference, ensuring your swirls come out beautifully marbled!
Are these cookies suitable for specific dietary needs?
Yes! This recipe is incredibly versatile. For a gluten-free option, swap the all-purpose flour for a gluten-free blend. You can also make them dairy-free by using vegan butter and dairy-free chocolate chips. Need them vegan? Replace the egg with a flax egg (1 tablespoon of ground flaxseed with 3 tablespoons of water, mixed and allowed to sit for 5 minutes). There’s something for everyone!
How can I avoid overbaking my cookies?
To ensure your cookies remain chewy and soft, keep a close eye on them as they bake. Look for lightly crackly tops as an indicator of doneness. Remember, they’ll continue to cook a bit after you remove them from the oven, so it’s better to underbake slightly than risk dryness.
