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 softened butter, and 1 cup brown sugar until the mixture is light and fluffy—about 2–3 minutes. Add 1 egg and 1 teaspoon of vanilla extract, mixing until well incorporated. In another bowl, whisk together 1 1/2 cups all-purpose flour, 1 teaspoon baking soda, and 1/4 teaspoon salt. Gradually combine the dry ingredients with the wet mixture until just combined, ensuring not to overmix.
Step 2: Prepare Brownie Dough
In a separate bowl, whisk together 1/2 cup melted butter and 1 cup white sugar until the mixture is smooth. Stir in 1/3 cup cocoa powder, 1 egg, and 1 teaspoon vanilla extract until fully blended. Next, fold in 1/2 cup all-purpose flour, 1/4 teaspoon baking powder, and 1/4 teaspoon salt, mixing until no dry ingredients remain. Finally, gently fold in 1/2 cup chocolate chips for that extra chocolatey goodness in your Peanut Butter Brownie Swirl Cookies.
Step 3: Chill Both Doughs
Cover both bowls with plastic wrap and place them in the refrigerator to chill for about 30 minutes. Chilling the dough helps firm up the mixtures, making them easier to scoop and swirl together. While the dough is chilling, you can preheat your oven to 350°F (175°C) for optimal baking conditions.
Step 4: Form the Cookies
Once the dough has chilled, line a baking sheet with parchment paper. Using a cookie scoop, take 1–2 tablespoons of the peanut butter dough and 1–2 tablespoons of the brownie dough, placing them next to each other on the baking sheet. Ensure they are slightly touching to create a beautiful blend when swirled. Use a toothpick or skewer to gently swirl the two doughs together for a marbled effect without overdoing it.
Step 5: Bake
Place the baking sheet in the preheated oven and bake the cookies for 9–11 minutes, or until the tops are slightly crackly and the edges are set. Keep an eye on them to ensure they don’t overbake, as you want to maintain that fudgy texture signature of these Peanut Butter Brownie Swirl Cookies.
Step 6: Cool Before Serving
After baking, allow the cookies to cool on the baking sheet for 5–10 minutes. This resting time lets them firm up just enough for easy transfer. Once they’re cool enough to handle, move the cookies to a wire rack to finish cooling completely. Your decadent Peanut Butter Brownie Swirl Cookies are now ready to be enjoyed!

Expert Tips for Peanut Butter Brownie Swirl Cookies
-
Texture Match: Ensure both doughs are similar in texture to create a successful swirl. If one is too soft or too firm, they won’t blend well.
-
Chill Time: Refrigerate the dough for at least 30 minutes. This step is crucial to firm up the dough, making it easier to scoop and swirl together without collapsing.
-
Use a Toothpick: When swirling, use a toothpick or skewer for gentle marbling. Avoid overmixing, as too much stirring can make the cookies lose their pretty swirl.
-
Consistent Sizing: Use a cookie scoop for uniform portions. This ensures even baking and consistent texture across all your Peanut Butter Brownie Swirl Cookies.
-
Watch the Bake: Keep an eye on the cookies as they bake; they are done when the tops look crackly and edges are set. Overbaking can lead to a dry texture.
How to Store and Freeze Peanut Butter Brownie Swirl Cookies
Room Temperature: Keep your cookies in an airtight container at room temperature for up to 5 days for optimal freshness.
Fridge: For longer storage, place the cookies in an airtight container in the fridge, where they will stay fresh for up to 1 week.
Freezer: Freeze the cookies in a single layer on a baking sheet, then transfer to a freezer-safe bag or container. They can be frozen for up to 3 months.
Reheating: When ready to enjoy, thaw at room temperature or warm them in the oven for a few minutes at 350°F (175°C) to restore their chewy texture.

Peanut Butter Brownie Swirl Cookies Recipe FAQs
What is the best way to select ripe ingredients for my Peanut Butter Brownie Swirl Cookies?
Absolutely! For your cookies, ensure your peanut butter is creamy and not too thick, which helps in achieving the perfect dough consistency. The butter should be softened to room temperature for easy mixing—about 20-30 minutes left out before you start preparing your dough works well! For eggs, use fresh ones, as they provide better binding.
How should I store my Peanut Butter Brownie Swirl Cookies?
To maintain freshness, store your cookies in an airtight container at room temperature for up to 5 days. If you’d like them to last longer, pop them in the fridge; they’ll stay fresh for up to a week wrapped tightly. Just make sure they’re cooled completely before storage to avoid moisture buildup!
Can I freeze my Peanut Butter Brownie Swirl Cookies, and if so, how should I do it?
Very! Freezing your cookies is a fantastic option for longer storage. Start by laying them out in a single layer on a baking sheet until they are firm. Then, transfer those beauties to a freezer-safe bag or container. You can freeze them for up to 3 months! When you want to enjoy them again, thaw at room temperature or warm them gently in the oven at 350°F (175°C) for a few minutes to regain their chewy goodness.
What if my cookie dough is too soft or too firm?
No worries! If your dough is too soft, try chilling it in the refrigerator for a bit longer—about 15 more minutes should do the trick. Conversely, if the dough feels too firm, you can incorporate a tiny splash of milk (dairy or non-dairy) or another egg if you aren’t vegan, and mix gently until it softens up to your desired consistency.
Are there any dietary considerations for my Peanut Butter Brownie Swirl Cookies?
Absolutely! If you have guests with dietary restrictions, you can easily adjust this recipe. For a gluten-free version, substitute all-purpose flour with a gluten-free blend. To make it dairy-free, swap traditional butter and chocolate with suitable dairy-free alternatives. If someone is avoiding eggs, replacing them with flax eggs (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water) works wonderfully!
Can I add extra ingredients like nuts or dried fruit to my cookies?
The more the merrier! Feel free to enhance your Peanut Butter Brownie Swirl Cookies by incorporating ingredients such as chopped nuts (walnuts or pecans work great) or dried fruits like cranberries or cherries for a delicious twist on flavor and texture. Customize these cookies to your preference, ensuring everyone’s happy at the table!
