Introduction
Peanut Butter Brownie Swirl Cookies combine the rich fudginess of brownie dough with the creamy, nutty flavor of peanut butter dough in a beautiful marbled cookie. These treats are chewy, flavorful, and perfect for sharing or savoring solo.

Ingredients
- For the Peanut Butter Dough:
- ½ cup creamy peanut butter
- ¼ cup butter, softened
- ½ cup brown sugar, packed
- 1 large egg
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- ½ teaspoon baking soda
- ¼ teaspoon salt
- For the Brownie Dough:
- ½ cup butter, melted
- 1 cup white sugar
- ⅓ cup cocoa powder
- 1 large egg
- 1 teaspoon vanilla extract
- ¾ cup all-purpose flour
- ¼ teaspoon baking powder
- ¼ teaspoon salt
- ½ cup chocolate chips
Instructions
- Step 1: Make the Peanut Butter Dough. In a medium bowl, beat together the peanut butter, softened butter, and brown sugar with an electric mixer until light and fluffy, about 2-3 minutes. Beat in the egg and vanilla extract until well combined.
- Step 2: In a separate bowl, whisk flour, baking soda, and salt. Gradually add these dry ingredients to the wet mixture, mixing on low or folding gently until just combined. Cover and refrigerate for at least 30 minutes.
- Step 3: Make the Brownie Dough. In another medium bowl, whisk melted butter and white sugar until smooth. Beat in cocoa powder, then add egg and vanilla, whisking until combined.
- Step 4: Whisk together flour, baking powder, and salt in a small bowl. Gently fold dry ingredients and chocolate chips into the wet mixture until no dry streaks remain. Cover and refrigerate for at least 30 minutes.
- Step 5: Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
- Step 6: Scoop 1-2 tablespoons of each dough and place side by side on the baking sheets. Use a toothpick or skewer to gently swirl the doughs together, creating a marbled effect. Leave about 2 inches between cookies.
- Step 7: Bake for 9-11 minutes until tops are lightly crackly and edges are set but centers remain soft. Avoid overbaking to keep cookies chewy.
- Step 8: Cool on the baking sheet for 5-10 minutes, then transfer to a wire rack to cool completely before enjoying.
Tips & Variations
- Chill both doughs thoroughly to prevent cookies from spreading too much during baking.
- Substitute almond, cashew, or sunflower seed butter for peanut butter for a different nutty flavor.
- Mix in chopped nuts, toffee bits, or other candies into either dough for added texture and taste.
- Use different types of chocolate chips like milk chocolate or white chocolate to customize flavor.
- For a gluten-free version, use a gluten-free all-purpose flour blend, keeping in mind texture may vary.
Storage
