Ingredients
For the Cookie Dough Layer:
- 1/2 cup unsalted butter, softened
- 1/2 cup light brown sugar, packed
- 1/4 cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1 1/4 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup semi-sweet chocolate chips
For the Middle Layer:
- 16-20 Original or Double Stuf Oreo cookies
For the Brownie Layer:
- 1/2 cup unsalted butter, melted
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/3 cup unsweetened cocoa powder
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt
Directions
Step 1: Preparation
Preheat your oven to 350°F (175°C). Line an 8×8-inch square baking pan with parchment paper, leaving an overhang on the sides. This allows you to lift the bars out easily once they are cool. Lightly grease the parchment with non-stick spray or butter.
Step 2: Mix the Cookie Dough Layer
In a medium bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy. Beat in the egg and vanilla extract. In a separate small bowl, whisk together the flour, baking soda, and salt. Gradually stir the dry ingredients into the wet ingredients until just combined. Fold in the chocolate chips. Press this dough evenly into the bottom of your prepared baking pan.
Step 3: Add the Oreo Layer
Place the Oreo cookies in a single layer over the top of the raw cookie dough. Pack them closely together so every bite of the finished bar contains a piece of cookie. You may need to break a few cookies to fill in any large gaps.
Step 4: Prepare the Brownie Batter
In a clean bowl, whisk the melted butter and sugar together. Add the eggs and vanilla, whisking until the mixture is smooth and glossy. Sift in the cocoa powder, flour, and salt. Gently fold the dry ingredients into the batter with a spatula until no white streaks remain. Pour the brownie batter over the Oreo layer and spread it to the edges with an offset spatula to cover the cookies completely.
Step 5: Baking and Cooling
Place the pan in the center of the oven and bake for 30 to 35 minutes. The edges should be set, but the center should still have a very slight jiggle. Do not overbake, as the brownies will continue to firm up as they cool. Remove from the oven and let the bars cool completely in the pan for at least 2 hours. Lifting them out while warm will cause the layers to separate. Slice into 16 squares and serve.

Expert Tips for Perfect Chewy Cakey Brownies Cookie Dough Easy Fudgy Stuffed Oreo Loaded Brookie Bars Classic Creative Chocolate Tested
For the best results, use room temperature eggs and butter for the cookie layer to ensure a smooth emulsion. When measuring your flour, use the “spoon and level” method rather than scooping directly with the measuring cup; this prevents the bars from becoming too dry or crumbly. If you want a truly fudgy brownie layer, avoid over-mixing the batter once you add the flour. Finally, patience is your best friend. Cooling these bars completely is the only way to get those clean, distinct layers when you slice into them.
Delicious Variations
You can easily customize these bars to suit your taste. Try using Golden Oreos or Mint Oreos for a different flavor profile in the center. If you love salt, sprinkle a pinch of flaky sea salt over the brownie batter before baking. For a “Peanut Butter Brookie,” swap the chocolate chips in the cookie layer for peanut butter chips and drizzle melted peanut butter over the finished bars. You can even add chopped walnuts or pecans to the brownie batter if you enjoy a nutty crunch.
Frequently Asked Questions
Can I use a boxed brownie or cookie mix?
Yes, you can substitute the homemade layers with your favorite store-bought mixes. Just follow the package instructions for each and layer them as directed in this recipe. Keep an eye on the bake time as it may vary slightly.
How do I store these brookie bars?
Store the bars in an airtight container at room temperature for up to 4 days. If you prefer them chilled, they will stay fresh in the refrigerator for up to a week.
Can I freeze these bars?
Absolutely. Wrap individual squares in plastic wrap and place them in a freezer-safe bag. They will stay delicious for up to 3 months. Thaw them at room temperature before eating.
Why did my brownies sink in the middle?
Brownies often sink if they are underbaked or if too much air was incorporated into the batter. Avoid over-whisking the eggs and make sure a toothpick inserted into the edge comes out clean, while the center stays slightly moist.
Can I double this recipe?
Yes, you can double the ingredients and bake them in a 9×13-inch pan. You may need to increase the baking time by 5 to 10 minutes, so check them frequently near the end of the timer.
Conclusion
These stuffed brookie bars are the ultimate solution for anyone who cannot decide on just one dessert. With layers of chewy cookie dough, crunchy Oreos, and fudgy brownies, they offer a complex flavor profile that everyone loves. They are simple to prepare and even easier to enjoy. Bake a batch for your next gathering, and watch them disappear in minutes. This tested recipe ensures you get a perfect balance of textures every single time.
