Tips & Tricks
Chill Both Doughs
Chilling the doughs for at least 30 minutes prevents excessive spreading and helps maintain the swirl pattern.

Do Not Over-Swirl
Gentle swirling preserves the marbled look, ensuring each cookie is a visual masterpiece.

Step-by-Step Instructions
Prepare the Peanut Butter Dough
Cream together the peanut butter, softened butter, and brown sugar until light and fluffy. Beat in the egg and vanilla extract until well combined. Separately, mix the flour, baking soda, and salt, then stir into the wet ingredients until just combined.
Prepare the Brownie Dough
In another bowl, whisk together the melted butter and granulated sugar. Mix in the cocoa powder, egg, and vanilla extract. Fold in the flour, baking powder, and salt until smooth, then stir in the chocolate chips.
Chill the Doughs
Cover and refrigerate both doughs for 30 minutes. This step is crucial for preventing excessive spreading during baking.
Form and Swirl the Cookies
Scoop equal portions of each dough and place them side by side on a parchment-lined baking sheet. Use a toothpick to gently swirl the doughs together, creating a marbled effect.
Bake the Cookies
Bake in a preheated oven at 350°F (175°C) for 9–11 minutes, or until the edges are set and the tops appear crackly. Let them cool briefly on the baking sheet before transferring to a wire rack to cool completely.
Delicious Variations
Nutty Delight
Add chopped peanuts or pecans to the peanut butter dough for an extra crunch.
Triple Chocolate
Incorporate white and milk chocolate chips into the brownie dough for a triple chocolate experience.
Spicy Twist
Add a pinch of cayenne pepper to the brownie dough for a subtle spicy kick.
