Step‑by‑Step Instructions for Peanut Butter Brownie Swirl Cookies
Step 1: Prepare Peanut Butter Dough
In a mixing bowl, beat together 1 cup of creamy peanut butter, 1/2 cup of softened butter, and 1 cup of brown sugar until the mixture is light and fluffy, about 2-3 minutes. Next, mix in 1 egg and 1 teaspoon of vanilla extract until well combined. In a separate bowl, whisk together 1 ½ cups of all-purpose flour, 1/2 teaspoon of baking soda, and a pinch of salt, then gradually combine with the wet ingredients, mixing just until incorporated.
Step 2: Prepare Brownie Dough
In another bowl, whisk together 1/2 cup of melted butter with 1 cup of white sugar until the mixture is smooth and glossy, which takes about 2 minutes. Add in 1/3 cup of cocoa powder, 1 egg, and 1 teaspoon of vanilla extract, stirring until well blended. Carefully fold in 1 cup of all-purpose flour, 1/2 teaspoon of baking powder, 1/4 teaspoon of salt, and 1/2 cup of chocolate chips until the brownie mixture is smooth.
Step 3: Chill Both Doughs
Once both the peanut butter and brownie doughs are prepared, cover each bowl with plastic wrap and refrigerate them for about 30 minutes. This chilling process helps firm up the doughs, making them easier to scoop and swirl later, while enhancing the flavors throughout the Peanut Butter Brownie Swirl Cookies.
Step 4: Shape and Swirl
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup. Using a cookie scoop or tablespoon, scoop 1-2 tablespoons of each dough and place them next to each other on the prepared baking sheet. With a toothpick or skewer, gently swirl the two types of dough together to create a beautiful marbled effect, ensuring some of each flavor shines through in every cookie.
Step 5: Bake
Bake the cookies in the preheated oven for 9-11 minutes, until the tops are lightly crackly and the edges are just set, which gives a perfect balance of chewy and soft textures. Allow the cookies to cool on the baking sheet for 5-10 minutes before transferring them to a wire rack to cool completely, letting the delightful aroma of Peanut Butter Brownie Swirl Cookies fill your kitchen.

Make Ahead Options
These Peanut Butter Brownie Swirl Cookies are perfect for those busy weeknights when you need a delightful treat without the hassle of last-minute baking! You can prepare both the peanut butter and brownie doughs up to 24 hours in advance. Simply combine the ingredients as outlined, cover each dough in plastic wrap, and refrigerate until you’re ready to bake. This not only saves time but also allows the flavors to meld beautifully! When you’re ready to serve, simply preheat your oven, scoop the dough onto a baking sheet, swirl them together, and bake as directed. You’ll end up with fresh, delectable cookies that are just as delicious as if you made them on the spot!

Peanut Butter Brownie Swirl Cookies Recipe FAQs
How do I choose the right peanut butter?
Absolutely! For the best flavor and texture, choose a creamy peanut butter that doesn’t contain added sugars or preservatives. Natural peanut butter is a fantastic option, as it provides a rich, nutty flavor while remaining smooth. If allergies are a concern, almond butter can be a delightful substitute. Just ensure it’s creamy to maintain the right cookie consistency.
What’s the best way to store these cookies?
Store your Peanut Butter Brownie Swirl Cookies in an airtight container at room temperature for up to 7 days. To keep them fresh, layer parchment paper between the cookies if they might stick together. If you want to enjoy them later, freeze them for up to 3 months! Just place them in a single layer on a baking sheet until frozen, then transfer to a freezer-safe bag—this helps prevent them from becoming squished.
Can I freeze the cookie dough?
Yes, you can freeze the cookie dough! After chilling the dough, scoop out the cookie portions as instructed and place them on a parchment-lined baking sheet. Freeze them until solid, then transfer to a freezer-safe bag. They can be stored for up to 3 months. To bake, just pop them straight from the freezer into a preheated oven, adding a minute or two to the baking time.
What if my cookie dough is too soft or too hard?
Very good question! If your peanut butter dough is too soft and difficult to swirl, try chilling it a bit longer in the refrigerator to firm it up. Conversely, if the dough is too hard, simply mix in a teaspoon of milk or a small amount of melted butter to soften it. Always aim for a consistency that allows easy scooping and swirling for those gorgeous marbled cookies!
Are there any allergy considerations for these cookies?
Definitely! For those with nut allergies, you can use sunbutter or another seed butter as a substitute for peanut butter in this recipe. Additionally, replace the regular butter with dairy-free butter to make it entirely dairy-free. Always check your chocolate chips if allergies are a concern, as some brands may contain dairy.
Can I make these cookies vegan?
Absolutely! To adapt your Peanut Butter Brownie Swirl Cookies for a vegan diet, replace the egg with a flaxseed meal mixture (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water, let it sit until it becomes gel-like). Also, use dairy-free butter and vegan chocolate chips for the brownie dough, and you’ll have a lovely vegan treat without compromising on taste!
