- Add a pinch of espresso powder to the brownie batter to enhance the chocolate flavor.
Storage

FAQs
Can I use milk chocolate instead of dark chocolate?
Yes, milk chocolate can be used, but it will result in a sweeter and less intense chocolate flavor.
Do I need to grease the pan if I use parchment paper?
No, lining the pan with parchment paper is enough to prevent sticking. Just ensure the paper is properly fitted before adding the layers.

Ingredients
Cookie Layer
- 1 ½ cups all-purpose flour
- ½ teaspoon baking soda
- ¼ teaspoon baking powder
- ¼ teaspoon salt
- ½ cup unsalted butter (softened)
- ½ cup granulated sugar
- ½ cup light brown sugar (packed)
- 1 teaspoon vanilla extract
- 1 egg
- ½ cup chocolate chips

Brownie Layer
- ½ cup unsalted butter (cubed)
- 6 ounces dark chocolate
- ½ cup granulated sugar
- 2 eggs
- ½ cup all-purpose flour
- ¼ cup cocoa powder
- ½ teaspoon salt
Instructions
- Prepare the Bakeware and Oven: Line a 9×9 inch baking dish with parchment paper and preheat your oven to 350°F (180ºC) to ensure it reaches the right temperature for baking.
- Mix Dry Ingredients for Cookie Layer: Sift together 1 ½ cups all-purpose flour, ½ teaspoon baking soda, ¼ teaspoon baking powder, and ¼ teaspoon salt to ensure even distribution and a light texture.
- Cream Butter and Sugars: In a separate bowl, cream ½ cup softened unsalted butter with ½ cup granulated sugar and ½ cup packed light brown sugar until the mixture is soft and creamy, approximately 5 minutes. This step is crucial for the proper texture.
- Add Egg and Vanilla: Incorporate 1 egg and 1 teaspoon vanilla extract into the creamed mixture, mixing until fully combined to maintain a smooth batter.
- Combine Wet and Dry Ingredients for Cookie Layer: Gradually add the dry ingredients to the wet mixture, folding gently with a spatula until combined. Fold in ½ cup chocolate chips carefully to avoid overmixing, which could toughen the dough.
- Form Cookie Base and Add Oreos: Transfer the cookie dough into the prepared baking dish and spread evenly. Arrange 24 Oreo cookies in a single layer over the cookie dough to create the middle layer and contrast in texture.
- Melt Butter and Chocolate for Brownie Layer: In a large heatproof bowl, melt ½ cup cubed unsalted butter and 6 ounces dark chocolate together using microwave increments of 1 minute or by using a double boiler until smooth.
- Mix Brownie Batter: Stir in ½ cup granulated sugar and 2 eggs into the melted chocolate mixture until shiny and fully incorporated. Then fold in ½ cup all-purpose flour, ¼ cup cocoa powder, and ½ teaspoon salt gently until just combined to maintain brownie fudginess.
- Assemble and Bake: Pour the brownie batter evenly over the Oreo cookies and cookie layer in the baking dish. Bake in the preheated oven for about 25 minutes, or until a toothpick inserted into the brownie layer comes out clean or with just a few moist crumbs.
- Cool and Serve: Allow the layered brownies to cool completely in the pan to set properly before slicing into 12 servings and serving.
Notes
- Do not overmix the cookie dough or brownie batter to keep the textures tender and fudgy.
- Using parchment paper makes it easier to lift the brownies out for cutting.
- Ensure the melted chocolate mixture is not too hot before adding eggs to avoid scrambling.
- The Oreos provide a crunchy middle layer that contrasts beautifully with the fudgy brownie and chewy cookie layers.
- Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate to extend freshness.
