Ingredients
Scale
- 1 cup unsalted butter, melted and slightly cooled
- 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
- 1 cup semi-sweet chocolate chips
- 16–20 Oreo cookies (Standard or Double Stuf)
- 1 cup prepared chocolate chip cookie dough (homemade or store-bought refrigerated dough)
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. Lightly grease the parchment with non-stick cooking spray or a bit of butter to ensure the brownies release perfectly after cooling.
- In a large mixing bowl, whisk together the melted butter and granulated sugar until well combined. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract. Sift in the cocoa powder, flour, and salt, then fold the dry ingredients into the wet mixture using a spatula until just combined. Be careful not to overmix, as this ensures a fudgy texture. Fold in the chocolate chips.
- Pour about half of the brownie batter into the prepared baking pan and spread it into an even layer. Arrange the Oreo cookies in a single layer across the batter. Take small pinches of the cookie dough and flatten them slightly with your fingers, placing them over and around the Oreos. This creates the “stuffed” effect that makes these brownies so special.
- Pour the remaining brownie batter over the Oreo and cookie dough layer. Use an offset spatula to gently spread the batter to the edges, ensuring all the fillings are covered. Place the pan in the center rack of the oven and bake for 30 to 35 minutes. The edges should be set, but the center should still have a slight jiggle for a fudgy finish.
- Remove the pan from the oven and let it cool completely on a wire rack. This is a crucial step; the stuffed layers need time to set so you get clean cuts. Once cooled, use the parchment paper overhang to lift the brownies out of the pan. Slice into 16 squares and serve.
