Equipment
- 9x13 inch baking pan
- Parchment paper
- Large mixing bowl
- Medium mixing bowl
- Hand mixer or whisk
- Spatula
- Wire cooling rack
Ingredients
Cookie Dough Layer:
- ½ cup unsalted butter softened
- ½ cup brown sugar packed
- ¼ cup granulated sugar
- 1 large egg
- 1 tsp vanilla extract
- 1 ¼ cups all purpose flour
- ½ tsp baking soda
- ¼ tsp salt
- 1 cup chocolate chips
Oreo Layer:
- 20 to 24 Oreo cookies broken into pieces
Brownie Layer:
- ½ cup unsalted butter melted
- 1 cup granulated sugar
- 2 large eggs
- 1 tsp vanilla extract
- ⅓ cup cocoa powder
- ½ cup all purpose flour
- ¼ tsp salt
- ¼ tsp baking powder
Instructions
- Make the Cookie Dough and Press It Into the PanCream the softened butter with the brown sugar and granulated sugar until light and fluffy. Mix in the egg and vanilla extract until fully combined, then fold in the flour, baking soda, and salt, followed by the chocolate chips, until a thick cookie dough forms.Press the dough evenly into the bottom of a parchment lined baking pan.
- Add the Oreo Layer and Mix the Brownie BatterBreak the Oreo cookies into rough pieces and scatter them evenly across the cookie dough base, covering the surface completely. In a separate bowl, whisk the melted butter and granulated sugar together until smooth, then whisk in the eggs and vanilla extract until glossy.Fold in the cocoa powder, flour, salt, and baking powder until a thick, glossy brownie batter forms.
- Assemble, Bake, and SlicePour the brownie batter evenly over the Oreo layer, spreading it out with a spatula until it reaches the edges of the pan.Bake until the brownie top looks set and slightly crackled and a toothpick comes out with a few moist crumbs. Let the pan cool completely on a wire rack before slicing into bars with a sharp knife.
Notes
- Line the pan with parchment paper for easy removal once the bars have cooled.
- Let the bars cool completely before slicing for clean, distinct layers.
- Spread the cookie dough into an even layer so it bakes uniformly under the Oreos and brownie batter.
- Avoid overbaking the brownie layer, since it will continue to set as it cools.
- Use a sharp, clean knife for neat slices, wiping it between cuts if needed.
- Room temperature butter and eggs help everything combine smoothly in both the cookie dough and brownie batter.
