Step‑by‑Step Instructions for Peanut Butter Brownie Swirl Cookies
Step 1: Make Peanut Butter Dough
In a mixing bowl, cream together ½ cup of creamy peanut butter, ½ cup of softened butter, and 1 cup of brown sugar until fluffy, about 2-3 minutes. Next, blend in one room-temperature egg and 1 teaspoon of vanilla extract. Gradually mix in 1 cup of all-purpose flour, ½ teaspoon of baking soda, and a pinch of salt until combined, ensuring no dry streaks remain.
Step 2: Make Brownie Dough
In a separate bowl, whisk ½ cup of melted butter with 1 cup of white sugar until smooth. Stir in ½ cup of unsweetened cocoa powder, one room-temperature egg, and 1 teaspoon of vanilla extract until well combined. Gently fold in ½ cup of all-purpose flour, ¼ teaspoon of baking powder, ¼ teaspoon of salt, and ½ cup of chocolate chips until just incorporated.
Step 3: Chill Doughs
Cover both doughs with plastic wrap and refrigerate for about 30 minutes. This helps the flavors meld while firming up the dough, making it easier to handle. Use this time to preheat your oven to 350°F (175°C) so it’s ready for baking as soon as the cookie doughs are chilled.
Step 4: Form Cookies
Line a baking sheet with parchment paper for easy cleanup. Use a cookie scoop to portion out the peanut butter dough and brownie dough side by side, about 2 inches apart. Take a toothpick and gently swirl the two doughs together, creating a beautiful marbled effect, but be careful not to overmix, as you want to retain the distinct layers.
Step 5: Bake
Place the baking sheet in the oven and bake the Peanut Butter Brownie Swirl Cookies for 9 to 11 minutes. Keep an eye on them; look for lightly crackly tops and set edges with soft centers. Remember, they will continue to cook slightly after removing from the oven due to residual heat.
Step 6: Cool
Once baked, allow the cookies to cool on the baking sheet for 5 to 10 minutes. This resting period helps them set up perfectly. Then, transfer them to a wire rack to cool completely, ensuring they achieve that delightful chewy texture while showcasing the stunning swirl design.

Expert Tips for Peanut Butter Brownie Swirl Cookies
- Dough Consistency Matters: Make sure both doughs are of similar thickness; this aids in achieving a beautiful swirl without mixing them too much.
- Avoid Overmixing: To maintain those distinct swirls, mix the doughs just until combined. Overmixing can blend them into one color, losing that appetizing look.
- Use a Cookie Scoop: For uniform sizes, use a cookie scoop when portioning the dough onto the baking sheet. This ensures even baking for your Peanut Butter Brownie Swirl Cookies.
- Watch for Visual Cues: Keep an eye on the cookies as they bake; look for lightly crackly tops and set edges. The centers should remain soft for the best texture.
- Cool Thoroughly: Let the cookies cool on the baking sheet for the recommended time to set properly, ensuring a delightful chewy finish.
How to Store and Freeze Peanut Butter Brownie Swirl Cookies
Airtight Container: Store the cookies in an airtight container at room temperature for up to 1 week to keep them fresh and chewy.
Fridge: For longer freshness and to maintain texture, you can store them in the fridge for up to 2 weeks; just allow them to come to room temperature before enjoying.
Freezer: Freeze the cookie dough for up to 3 months for a quick treat later. Scoop and place the dough portions on a parchment-lined baking sheet, freeze until solid, then transfer to a zip-top bag.
Reheating: To enjoy your cookies warm, simply reheat in the microwave for about 10-15 seconds or in a preheated oven at 350°F (175°C) for a few minutes until just warmed.

Peanut Butter Brownie Swirl Cookies Recipe FAQs
How should I choose ripe ingredients?
Absolutely! Selecting the right ingredients is crucial for the best flavor in your Peanut Butter Brownie Swirl Cookies. For the creamy peanut butter, opt for a brand that uses minimal additives—natural options are usually best. Ensure your butter is softened at room temperature to mix easily. If using eggs, choose ones that are fresh and at room temperature to aid in fluffiness.
What’s the best way to store leftover cookies?
Very! To keep your Peanut Butter Brownie Swirl Cookies fresh, store them in an airtight container at room temperature for up to one week. For longer storage, place them in the fridge, and they can last up to two weeks. Remember to let them come back to room temperature before enjoying them for the best taste and texture!
Can I freeze the dough, and how do I do it?
Absolutely! Freezing your cookie dough is a fantastic way to have freshly baked cookies ready at any time. To do this, scoop cookie portions onto a parchment-lined baking sheet and freeze them until solid, about 1-2 hours. Once frozen, transfer the dough to a zip-top bag labeled with the date. They can be stored in the freezer for up to three months! When you’re ready, bake directly from the freezer, adding a minute or two to the baking time.
What should I do if my cookies spread too much while baking?
If you notice that your Peanut Butter Brownie Swirl Cookies spread more than expected, there could be a couple of culprits! Ensure your butter is at the right temperature—if it’s too warm, it can cause excess spreading. Additionally, make sure you’ve measured your flour accurately; using too little can lead to flatter cookies. If you’re using a lighter flour, consider chilling the dough for a bit longer before baking to help them hold their shape.
Are there any dietary considerations I should be aware of?
Definitely! When preparing your Peanut Butter Brownie Swirl Cookies, consider any allergies or dietary restrictions. If anyone is allergic to nuts, I recommend substituting peanut butter with sunflower butter. For dairy-free options, you can use dairy-free butter, milk, and chocolate chips. Plus, this recipe can easily be made gluten-free by substituting the all-purpose flour with a 1:1 gluten-free flour blend, making it suitable for a wider range of diets.
