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 and prepare pan: Preheat your oven to 350°F (180°C). Lightly grease a 9×13 inch (23×33 cm) baking pan, then line it with parchment paper leaving an overhang for easy removal. Greasing first helps the parchment stick securely.
  2. Make the chocolate chip cookie layer: In a large bowl, beat softened butter with brown and white sugars until combined. Add the egg, egg yolk, and vanilla extract, mixing well. On low speed, beat in the flour and salt until just incorporated. Turn off the mixer and fold in the chocolate chips using a spatula. Spread this cookie dough evenly in the prepared pan.
  3. Add the Oreo cookie layer: Arrange Oreo cookies evenly over the cookie dough, pressing down slightly to ensure they stick. The recipe uses 28 cookies arranged in 7 rows of 4 with some halves to cover completely.
  4. Prepare the brownie batter: Finely chop the dark chocolate. In a heatproof bowl, combine the chocolate and cubed butter. Microwave in 45-second intervals on medium power, stirring between each, until melted and smooth. Let it cool for about 5 minutes.
  5. Combine brownie ingredients: Whisk the eggs and granulated sugar into the cooled chocolate mixture until smooth. Sift and then add the flour, cocoa powder, and salt, folding gently until just combined.
  6. Top the Oreos with brownie batter: Spoon dollops of brownie batter evenly over the Oreo layer, then carefully spread smooth to cover the cookies completely. Spreading in sections helps avoid disturbing the Oreo layer.
  7. Bake the brownies: Bake in the preheated oven for 37 to 45 minutes, or until a toothpick inserted comes out dry or with a few moist crumbs. Baking times vary based on oven and desired gooeyness.
  8. Cool and serve: Allow the brownies to cool fully for at least 4 hours in the pan. Use the parchment paper overhang to lift the slab out, then slice on a cutting board. Store leftovers in an airtight container at room temperature for up to 4 days.

Notes

  • Do not microwave chocolate on high power as it can burn or become grainy; use medium power and stir between intervals.
  • Discard the white of the second egg to achieve the proper texture for the cookie layer.
  • Sifting the cocoa powder and flour for the brownie layer ensures a smoother batter.
  • Full cooling is essential for clean slicing and best texture.
  • Use high-quality dark chocolate (50-70% cocoa) for a rich brownie flavor.
