Ingredients
Scale
- 1 cup unsalted butter, melted
- 2 cups granulated sugar
- 4 large eggs, room temperature
- 1 tablespoon vanilla extract
- 3/4 cup unsweetened cocoa powder
- 1 cup all-purpose flour
- 1/2 teaspoon salt
- 8 oz cream cheese, softened
- 1/4 cup powdered sugar
- 16–20 Oreo cookies
- 1 cup chocolate chip cookie dough (homemade or store-bought)
- 1/2 cup semi-sweet chocolate chips
Instructions
- Preheat your oven to 350°F (175°C). Line a 9×9 inch square baking pan with parchment paper, leaving an overhang on the sides for easy removal later. Lightly grease the parchment with non-stick cooking spray.
- In a large bowl, whisk the melted butter and granulated sugar until well combined. Add three of the eggs and 2 teaspoons of vanilla extract, beating until the mixture is smooth and slightly pale. Sift in the cocoa powder, flour, and salt. Fold the dry ingredients into the wet ingredients using a spatula until just combined. Be careful not to overmix, as this keeps the texture chewy yet cakey.
- In a separate medium bowl, beat the softened cream cheese, powdered sugar, the remaining egg, and the remaining teaspoon of vanilla extract. Mix until the consistency is creamy and free of lumps. Set this aside for the layering process.
- Pour about two-thirds of the brownie batter into the prepared pan and spread it evenly. Arrange a single layer of Oreo cookies on top of the batter. Pour the cream cheese mixture over the Oreos, spreading it to the edges. Drop small spoonfuls of the remaining brownie batter and chunks of the chocolate chip cookie dough over the cheesecake layer. Use a knife to gently swirl the top layers for a marble effect.
- Sprinkle the semi-sweet chocolate chips over the top. Place the pan in the center rack of the oven and bake for 40 to 45 minutes. The center should be set but still have a slight jiggle. Remove from the oven and let the bars cool completely in the pan. For the best results and cleanest cuts, refrigerate the bars for at least 2 hours before slicing.
