Ingredient Notes
The success of this cookie dough Oreo brownies recipe depends on quality ingredients and proper preparation. Use high-quality cocoa powder for a deep chocolate flavor, and don’t skip heat-treating the flour for the cookie dough layer—it ensures it’s safe to eat raw.
The Oreos act as a delicious barrier between the brownie and cookie dough layers, adding both texture and that iconic cookies-and-cream flavor.
Step-by-Step Instructions
1. Prepare the Brownie Batter
In a large bowl, mix melted butter, sugar, and cocoa powder until smooth. Add eggs and vanilla, then stir in flour and salt until just combined.

2. Layer the Oreos
Pour half of the brownie batter into a lined baking pan. Arrange Oreos evenly on top, then cover with the remaining batter.
3. Bake
Bake at 350°F for 30–35 minutes, or until the brownies are set. Let them cool completely before adding the cookie dough layer.

4. Make the Cookie Dough
Cream butter, brown sugar, and granulated sugar. Add milk and vanilla, then mix in heat-treated flour and chocolate chips.
5. Assemble
Spread the cookie dough evenly over the cooled brownies. Press gently to create a smooth top layer.

6. Chill and Slice
Refrigerate for at least 1 hour before slicing into squares.
