Ingredients for Peanut Butter Brownie Swirl Cookies
- 1 cup (226g) unsalted butter, melted
- 1 cup (200g) granulated sugar
- 1 cup (220g) packed light brown sugar
- 2 large eggs
- 2 teaspoons pure vanilla extract
- 2 cups (250g) all-purpose flour
- 1 cup (85g) unsweetened cocoa powder
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 cup (175g) semi-sweet chocolate chips
- ½ cup (120g) creamy peanut butter
How to Make Peanut Butter Brownie Swirl Cookies
Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.
Step 2: Mix the Brownie Cookie Dough
In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth. Add eggs and vanilla extract, whisking until combined. Sift in the flour, cocoa powder, baking soda, and salt, then stir until just combined. Fold in the chocolate chips.
Step 3: Swirl in the Peanut Butter
Warm the peanut butter in the microwave for about 20 seconds until it’s pourable. Drop spoonfuls of dough (about 2 tablespoons each) onto the prepared baking sheets. Drizzle or dollop about 1 teaspoon of warm peanut butter onto each mound of dough. Use a toothpick or skewer to gently swirl the peanut butter into the top of each cookie, creating a marbled effect.
Step 4: Bake the Cookies
Bake the cookies for 10-12 minutes, or until the edges are set and the centers still look slightly soft. Don’t overbake—these are best when fudgy! Let the cookies cool on the baking sheets for 5 minutes before transferring to a wire rack to cool completely.
Step 5: Serve and Enjoy
Enjoy your Peanut Butter Brownie Swirl Cookies warm, with a glass of milk or your favorite beverage!
