Directions
Step 1: Prepare the Cookie Dough Layer
- Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking pan and line with parchment paper for easy removal.
- In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth.
- Beat in the eggs and vanilla extract.
- Stir in the flour, baking soda, and salt just until combined. Fold in chocolate chips.
- Press the cookie dough evenly into the bottom of your prepared pan.
Step 2: Add the Oreo Layer
- Arrange 24 Oreo cookies in a single layer over the cookie dough, gently pressing them down.
Step 3: Prepare and Pour the Brownie Layer
- In a medium bowl, prepare the brownie mix according to the package instructions.
- Slowly pour the brownie batter over the Oreo layer, spreading evenly with a spatula.
Step 4: Bake
- Bake in the preheated oven for 40-45 minutes, or until a toothpick inserted into the brownie layer comes out with just a few moist crumbs (not wet batter).
- Cool completely in the pan before cutting into squares for clean layers.
Notes
- Let the brownies cool fully before slicing for neat, beautiful layers.
- If you like gooier brownies, check for doneness at 38-40 minutes; for firmer, bake up to 47 minutes.
- You can use parchment overhangs to lift the brownies out easily.

- Peanut Butter Slutty Brownies: Swap in peanut butter Oreos and swirl peanut butter into the brownie layer before baking.
- Gluten-Free Version: Use gluten-free flour and Oreos, plus a gluten-free brownie mix.
