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 Oven: Preheat your oven to 350°F (180°C) to ensure it’s ready for baking the slutty brownies.
  2. Prepare Baking Pan: Lightly grease a 9×13 inch (23×33 cm) baking pan. Line it with parchment paper, leaving an overhang on the sides for easy removal later. Greasing the pan first helps the parchment paper stick securely.
  3. Make Chocolate Chip Cookie Layer: In a large bowl, beat together the softened butter, brown sugar, and white sugar until fully combined and creamy.
  4. Add Egg and Vanilla: Beat in one whole egg, the additional egg yolk (discard the second egg’s white), and vanilla extract, ensuring the mixture is smooth.
  5. Incorporate Dry Ingredients: With your mixer on low, gradually add the flour and salt to the wet mixture. Once combined, turn off the mixer and fold in the chocolate chips using a rubber spatula or wooden spoon for even distribution.
  6. Form Cookie Layer: Spread this cookie dough evenly in the prepared baking pan using a spatula, smoothing out the surface.
  7. Add Oreo Layer: Arrange the 28 Oreo cookies on top of the cookie dough layer, pressing them down slightly to ensure they stick. Arrange in 7 rows of 4 cookies, filling gaps with half cookies for complete coverage.
  8. Prepare Brownie Batter – Melt Chocolate and Butter: Finely chop the dark chocolate. Place it along with the cubed butter into a heatproof bowl. Microwave on medium power in 45-second intervals, stirring between each, until melted and smooth. Avoid high power to prevent grainy or burnt chocolate.
  9. Cool Chocolate Mixture and Add Eggs and Sugar: Let the melted chocolate mixture cool for about 5 minutes, then whisk in the two large eggs and granulated sugar until smooth.
  10. Add Dry Ingredients for Brownie Batter: Sift together the flour, cocoa powder, and salt to remove lumps. Whisk these dry ingredients into the chocolate mixture until just combined, taking care not to overmix.
  11. Layer Brownie Batter: Spoon the brownie batter over the Oreo cookies in small dollops. Spread the batter evenly across the pan with a spatula, gently covering the Oreos without disturbing them.
  12. 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 depending on your preferred fudginess.
  13. Cool Completely: Remove the brownies from the oven and allow them to cool fully, at least 4 hours, for the layers to set properly.
  14. Slice and Serve: Use the parchment paper overhang to lift the brownies from the pan. Place on a cutting board and cut into squares. Serve and enjoy!
  15. Storage: Store any leftovers in an airtight container at room temperature for up to 4 days to maintain freshness.

Notes

  • Using parchment paper with an overhang makes it easier to lift the brownies from the pan without breaking them.
  • When melting chocolate and butter, always microwave on medium power in intervals to avoid burning the chocolate.
  • Sifting the flour and cocoa powder prevents lumps and ensures a smooth batter.
  • Allowing the brownies to cool fully before slicing helps the layers to set and prevents them from falling apart.
  • Adjust baking time based on your oven and desired moistness; less time for gooier brownies, more for firmer ones.
