Ingredients

Scale

Chocolate Chip Cookie Layer

  • 3/4 cup unsalted butter (168 grams), softened
  • 1/2 cup brown sugar (105 grams)
  • 1/2 cup white sugar (100 grams)
  • 1 large egg
  • 1 large egg yolk (discard the white)
  • 1 teaspoon vanilla extract
  • 1 1/2 cups all-purpose flour (188 grams)
  • 1/4 teaspoon salt
  • 2/3 cups chocolate chips (120 grams)

Oreo Layer

  • 28 Oreo cookies

Brownie Batter

  • 1/2 cup unsalted butter (112 grams), cubed
  • 6 oz dark chocolate (170 grams), 50-70% cocoa or semi-sweet
  • 1 cup granulated sugar (200 grams)
  • 2 large eggs
  • 1/2 cup all-purpose flour (63 grams)
  • 1/4 cup cocoa powder (23 grams)
  • 1/2 teaspoon salt

Instructions

  1. Preheat the oven: Set the oven to 350°F (180°C) to ensure it reaches the proper temperature for baking the layered dessert.
  2. Prepare the pan: Lightly grease a 9×13 inch (23×33 cm) pan, then line it with parchment paper leaving an overhang for easy removal later. Greasing first helps the parchment stick to the pan.
  3. Make the cookie dough base: In a large bowl, beat the softened butter with brown sugar and white sugar until combined. Add the egg, egg yolk, and vanilla extract, mixing until smooth.
  4. Add dry ingredients to cookie dough: With the mixer on low, gradually beat in the flour and salt until almost incorporated, then gently fold in the chocolate chips using a rubber spatula or wooden spoon to maintain the dough’s texture.
  5. Spread cookie dough: Spoon the cookie dough into the prepared pan and spread it evenly with a spatula to create a smooth base layer.
  6. Add Oreo layer: Arrange the Oreo cookies over the cookie dough pressing down lightly to adhere. Use 7 rows of 4 cookies with some halves to cover the layer completely.
  7. Prepare the brownie batter: Finely chop the dark chocolate. Combine the chopped chocolate and cubed butter in a large heatproof bowl and microwave in 45-second intervals on medium power, stirring between each, until smooth and melted. Avoid high power to prevent burning.
  8. Cool chocolate mixture and add eggs: Let the melted chocolate and butter mixture cool about 5 minutes. Then whisk in the eggs and granulated sugar thoroughly.
  9. Add dry ingredients to brownie batter: Sift together the flour, cocoa powder, and salt, then whisk into the chocolate mixture until just combined without overmixing.
  10. Spread brownie batter: Drop spoonfuls of the brownie batter over the Oreo layer and gently spread with a spatula to cover evenly, ensuring not to disturb the Oreo cookies.
  11. Bake: Place the pan in the preheated oven and bake for 37-45 minutes. Check doneness by inserting a toothpick; it should come out dry or with a few moist crumbs. Baking time varies by oven and desired gooeyness.
  12. Cool completely: Let the brownies cool fully at room temperature, at least 4 hours, to firm up before slicing.
  13. Remove and slice: Use the parchment paper overhang to lift the brownies out of the pan. Transfer to a cutting board and slice into squares.
  14. Storage: Store leftover brownies in an airtight container at room temperature for up to 4 days to maintain freshness.

Notes

  • Discard the white of the second egg to keep the cookie layer’s texture just right.
  • If cocoa powder and flour are lumpy, sift them before adding to the brownie batter for a smooth consistency.
  • Microwaving the chocolate and butter at medium power prevents grainy or burnt chocolate.
  • Cooling the brownies completely before slicing helps maintain their structure and prevents crumbling.
  • You can customize the Oreo layer by using different Oreo varieties if desired.
