Peanut Butter Brownie Swirl Cookies Recipe
Introduction
Peanut Butter Brownie Swirl Cookies combine the rich, fudgy taste of brownies with the creamy, nutty flavor of peanut butter. These marbled treats are easy to make and perfect for satisfying your sweet tooth.

Ingredients
- For the Brownie Layer:
- 1/2 cup (1 stick) unsalted butter, melted
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/3 cup unsweetened cocoa powder
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt
- 1/4 teaspoon baking powder
- For the Peanut Butter Layer:
- 1/2 cup creamy peanut butter
- 1/4 cup unsalted butter, softened
- 1/2 cup granulated sugar
- 1/4 cup brown sugar, packed
- 1 large egg
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
Instructions
- Step 1: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Step 2: In a medium bowl, whisk together the melted butter, granulated sugar, eggs, and vanilla extract until smooth. Stir in the cocoa powder, flour, salt, and baking powder until just combined. Set aside.
- Step 3: In another bowl, beat together the peanut butter, softened butter, granulated sugar, and brown sugar until creamy. Mix in the egg and vanilla extract until well combined. Gradually add the flour, baking soda, and salt, mixing until just combined.
- Step 4: Drop spoonfuls of the brownie batter and peanut butter dough onto the prepared baking sheet, alternating between the two. Use a toothpick or the tip of a knife to gently swirl the two batters together, creating a marbled effect.
- Step 5: Bake in the preheated oven for 10-12 minutes, or until the edges are set and the centers look slightly underbaked. Remove from the oven and let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Tips & Variations
- For extra texture, add chopped peanuts or chocolate chips to the peanut butter layer before swirling.
- Use natural peanut butter for a more intense peanut flavor, but reduce added salt in the recipe accordingly.
- If you prefer chewier cookies, slightly underbake and allow them to set on the baking sheet before moving.
Storage
Store the cookies in an airtight container at room temperature for up to 5 days. You can also freeze them for up to 3 months; thaw at room temperature before serving. To refresh, warm briefly in the oven for a soft texture.

Notes
- For best results, do not overmix the batters once the dry ingredients are added to avoid tough cookies.
- Ensure the peanut butter and butter for the peanut butter layer are softened to get a smooth, creamy texture.
- You can store the cookies in an airtight container at room temperature for up to 5 days.
- Feel free to substitute crunchy peanut butter for creamy for added texture.
- Swirling the batters just a few times is enough to create the marbled look without fully blending the two doughs.
