If you’re a fan of classic peanut butter cups, get ready for your new favorite treat! These Peanut Butter Brownie Swirl Cookies are the ultimate mashup of rich, fudgy brownie and creamy peanut butter cookie dough—swirled together for a flavor explosion in every bite.
With bold chocolate, nutty peanut butter, and a mesmerizing marbled look, these cookies are just as stunning as they are delicious!
Why You’ll Love These Cookies
This recipe brings together two beloved desserts into one portable, mouthwatering cookie. Here’s what makes it so irresistible:
- The Brownie Dough: Rich, deep chocolate flavor from cocoa powder and chocolate chips gives each bite a gooey, fudgy texture.
- The Peanut Butter Dough: Creamy, smooth, and full of roasted peanut flavor, this dough balances out the boldness of the brownie perfectly.
- The Swirl: That gorgeous marbling? It’s not just pretty—it ensures every bite is the perfect chocolate–peanut butter combo.
Tips for Perfect Swirls
- Soft, Scoopable Doughs: Make sure both doughs are thick but soft. Room-temperature butter and eggs are key.
- Don’t Overmix: You want distinct swirls, not a muddy blend. A few gentle turns with a toothpick is all you need.
- Use a Cookie Scoop: For even portions and symmetrical cookies, a cookie scoop makes all the difference.
- Watch While Baking: Look for crackly tops and slightly set edges—the centers should still be soft when they come out of the oven.
Easy Substitutions
These cookies are easy to adapt based on your dietary preferences:
- Gluten-Free: Use a 1:1 gluten-free baking flour blend.
- Dairy-Free: Choose plant-based butter and chocolate chips.
- Vegan: Use dairy-free products and swap in a flax egg (1 tbsp flaxseed + 2.5 tbsp water).
- Refined Sugar-Free: Replace white and brown sugar with coconut sugar or monk fruit sweetener.
Ingredients
For the Peanut Butter Dough:
- ½ cup creamy peanut butter
- ¼ cup butter, softened
- ½ cup brown sugar
- 1 egg
- 1 tsp vanilla extract
- 1 cup all-purpose flour

- ⅓ cup cocoa powder
- 1 egg

- ¾ cup all-purpose flour
- ¼ tsp baking powder

Instructions
- Make the Peanut Butter Dough:
In a large bowl, cream together the peanut butter, softened butter, and brown sugar until fluffy. Mix in the egg and vanilla. In a separate bowl, whisk together the flour, baking soda, and salt, then mix into the wet ingredients until just combined. - Make the Brownie Dough:
In another bowl, stir together the melted butter and sugar. Whisk in the cocoa powder, then add the egg and vanilla. Stir in the flour, baking powder, salt, and chocolate chips. - Chill Both Doughs:
Cover and chill each dough for 30 minutes for easier swirling and better texture. - Shape and Swirl:
Scoop 1–2 tablespoon portions of each dough and place them side by side on a parchment-lined baking sheet. Use a toothpick or skewer to gently swirl the doughs together. - Bake:
Bake at 350°F (175°C) for 9–11 minutes until the tops are just crackled and the edges are set. The centers should still be soft. - Cool:
Let the cookies rest on the baking sheet for 5–10 minutes before transferring them to a wire rack to cool completely.
