Step-by-Step Instructions
Step 1: Make the Cookie Dough Layer
- Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper.
- In a bowl, cream together the butter, brown sugar, and granulated sugar until light and fluffy.
- Beat in the eggs and vanilla extract.
- Whisk together the flour, baking soda, and salt, then mix into the wet ingredients.
- Stir in the chocolate chips.
- Press the cookie dough evenly into the bottom of your prepared pan. Use clean, damp hands or a spatula for even distribution.
Step 2: Add the Oreo Layer
- Arrange Oreo cookies in a single layer over the cookie dough. It’s okay if they overlap slightly.
Step 3: Prepare the Brownie Batter
- In a separate bowl, whisk together melted butter and sugar until smooth.
- Add eggs and vanilla; whisk until well combined.
- Sift in the cocoa powder, flour, salt, and baking powder. Stir just until no streaks remain.
- Pour the brownie batter over the Oreo layer and spread evenly with a spatula.
Step 4: Bake
- Bake for 35–40 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter).
- If the top is browning too quickly, cover loosely with foil for the last 10 minutes.
Step 5: Cool and Slice
- Cool completely in the pan on a rack for at least 30 minutes before slicing.
- Use the parchment overhang to lift the brownies and slice into bars.

Common Mistakes to Avoid
- Undercooking: The layers are thick—make sure the center is set before removing from the oven.
- Overmixing Brownie Batter: Stir just until combined for fudgy, not cakey, brownies.
- Overlapping Oreos: It’s okay if they touch, but too much overlap can make the center gooey.
- Rushing Cooling: Let brownies cool completely for neat, even slices.
