Ingredients
- 1 box (18.3 oz) brownie mix
- 1/4 cup all-purpose flour
- 2 large eggs
- 1/2 cup vegetable oil
- 1 cup creamy peanut butter
- 1 cup powdered sugar
- 4 oz semi-sweet chocolate chips
- 1 tbsp unsalted butter
Directions
Prepare the Dough
Preheat your oven to 350°F (175°C). In a large bowl, combine the brownie mix, flour, eggs, and vegetable oil. Stir until well combined and a thick dough forms.
Shape the Cookies
Roll the dough into 1-inch balls and place them on a baking sheet lined with parchment paper, spacing them about 2 inches apart. Flatten each ball slightly with your fingers.
Bake the Cookies
Bake in the preheated oven for 10-12 minutes, or until the edges are set. Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Prepare the Peanut Butter Filling
While the cookies are cooling, mix the peanut butter and powdered sugar in a medium bowl until smooth and creamy. Roll into small balls and slightly flatten them.
Assemble the Cookies
Place a peanut butter disk on top of each cookie, pressing gently to adhere. Melt the chocolate chips and butter in a small bowl over simmering water, stirring until smooth. Drizzle over the cookies.

Notes
- If the dough is too sticky, chill it in the refrigerator for 15 minutes before rolling. Learn more about dough handling.
- For a richer chocolate flavor, try using dark chocolate chips instead.
- Store cookies in an airtight container to maintain freshness.
