Directions

1. Preheat the oven to 350°F (175°C). Grease and line a 9×9-inch baking pan with parchment paper.

2. Prepare the brownie mix according to the package instructions. In a large bowl, mix together the brownie mix, melted butter, eggs, vanilla extract, and water.

3. Pour the brownie batter into the prepared pan and spread it out evenly.

4. Sprinkle the crushed Oreo cookies over the brownie batter.

5. In a medium bowl, mix together the peanut butter and powdered sugar until smooth. Fold in the whipped topping until fully combined.

6. Spoon the peanut butter mixture over the brownie and Oreo layers. Spread it out evenly using a spatula.

7. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean (a few moist crumbs are fine due to the peanut butter layer).

8. Let the bars cool in the pan for about 15 minutes before transferring to a wire rack to cool completely.

9. Once cooled, cut into squares and serve.
