How to Make Peanut Butter Brownie Swirl Cookies
Step 1: Prepare the Peanut Butter Dough
In a bowl, beat together the creamy peanut butter, softened butter, and brown sugar until light and fluffy. Then, add in the egg and vanilla extract. In another bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually mix this dry mixture into the wet ingredients until just combined.
Step 2: Prepare the Brownie Dough
In a separate bowl, whisk together the melted butter with the white sugar. Mix in the cocoa powder until smooth. Then add in the second egg, along with its corresponding vanilla extract. Finally, fold in the remaining flour, baking powder, salt, and chocolate chips until no dry streaks remain.
Step 3: Chill Both Doughs
Chill both doughs in the refrigerator for about 30 minutes. This helps maintain their shape during baking.
Step 4: Scoop & Swirl
Using a spoon or cookie scoop, take 1–2 tablespoons of each dough. Place them side by side on a parchment-lined baking sheet. Use a toothpick or skewer to gently swirl the two doughs together in a marble pattern.
Step 5: Bake
Preheat your oven to 350°F (175°C). Bake for 9–11 minutes until the tops are lightly crackly and edges are just set. The centers should remain soft.
Step 6: Cool & Enjoy
Allow to cool on the baking sheet for 5–10 minutes before transferring to a wire rack to cool completely. Enjoy your homemade Peanut Butter Brownie Swirl Cookies!

Common Mistakes to Avoid
