Peanut Butter Brownie Swirl Cookies Recipe
Introduction
Peanut Butter Brownie Swirl Cookies combine two beloved flavors into one irresistible treat. These cookies feature rich, fudgy brownie dough swirled with creamy peanut butter for a perfect balance of sweet and nutty. They’re simple to make and perfect for any occasion.

Ingredients
- 1/2 cup creamy peanut butter
- 1/4 cup butter (softened)
- 1/2 cup brown sugar
- 1 egg
- 1 tsp vanilla extract
- 1 cup all-purpose flour
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1/2 cup butter (melted)
- 1 cup white sugar
- 1/3 cup cocoa powder
- 1 additional egg
- 1 tsp vanilla
- 3/4 cup all-purpose flour
- 1/4 tsp baking powder
- 1/4 tsp salt
- 1/2 cup chocolate chips
Instructions
- Step 1: Make the peanut butter dough by beating the peanut butter, softened butter, and brown sugar until light and fluffy. Add the egg and vanilla extract, mixing well. In a separate bowl, whisk together 1 cup flour, baking soda, and salt, then gradually stir into the wet ingredients until just combined.
- Step 2: Prepare the brownie dough by whisking melted butter and white sugar. Beat in cocoa powder until smooth, then add the egg and vanilla. Fold in 3/4 cup flour, baking powder, salt, and chocolate chips until no dry streaks remain.
- Step 3: Chill both doughs in the refrigerator for 30 minutes. Once chilled, scoop 1 to 2 tablespoon portions of each dough side by side onto a parchment-lined baking sheet. Use a toothpick or skewer to gently swirl the two doughs together creating a marble pattern.
- Step 4: Bake in a preheated oven at 350°F (175°C) for 9 to 11 minutes. Cookies are done when the tops are lightly crackly and edges are set, though centers will remain soft.
- Step 5: Let cookies cool on the baking sheet for 5 to 10 minutes, then transfer to a wire rack to cool completely before serving. Enjoy your delicious peanut butter brownie swirl cookies!
