Ingredients

Scale

Chocolate Chip Cookie Layer

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

Oreo Cookie Layer

  • 28 Oreo cookies

Brownie Batter

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

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (180°C) to prepare for baking the Slutty Brownies.
  2. Prepare Baking Pan: Lightly grease a 9×13 inch (23×33 cm) baking pan and line it with parchment paper, leaving an overhang on the sides for easy removal later. Greasing helps the paper stick properly.
  3. Make Chocolate Chip Cookie Layer: In a large bowl, beat together the softened butter, brown sugar, and white sugar until well combined and creamy.
  4. Add Eggs and Vanilla: Beat in the large egg, additional egg yolk, and vanilla extract, ensuring not to add the second whole egg but only the yolk.
  5. Incorporate Dry Ingredients: With the mixer on low speed, gradually beat in the all-purpose flour and salt until just combined.
  6. Mix in Chocolate Chips: Turn off the mixer and fold in the chocolate chips using a rubber spatula or wooden spoon to distribute evenly.
  7. Spread Cookie Dough: Spoon the cookie dough mixture into the prepared pan and spread it smooth with a spatula creating an even base layer.
  8. Add Oreo Layer: Place the Oreo cookies evenly on top of the cookie dough layer, gently pressing them down slightly to adhere. Arrange about 7 rows of 4 cookies plus a few halves to fully cover.
  9. Prepare Brownie Batter – Melt Chocolate & Butter: Finely chop the dark chocolate, then place it with cubed butter in a heatproof bowl. Microwave on medium power in 45-second intervals, stirring between each to melt smoothly without burning.
  10. Cool and Add Eggs & Sugar: Allow the melted chocolate mixture to cool for about 5 minutes before whisking in the 2 large eggs and granulated sugar until combined.
  11. Add Dry Ingredients to Brownie Batter: Sift together all-purpose flour, cocoa powder, and salt, then whisk them into the chocolate mixture until just combined to avoid lumps.
  12. Spread Brownie Batter Over Oreos: Drop spoonfuls of the brownie batter evenly across the Oreo layer and gently spread smooth using the back of a spoon or spatula to cover fully.
  13. Bake Brownies: Place the pan in the preheated oven and bake for 37-45 minutes until a toothpick inserted in the center comes out dry or with a few moist crumbs, depending on your preferred gooeyness.
  14. Cool Completely: Allow the brownies to cool fully in the pan for at least 4 hours to set properly before slicing.
  15. Slice and Serve: Use the parchment paper overhang to lift the brownies from the pan. Transfer to a cutting board and cut into squares.
  16. Storage: Store any leftover brownies at room temperature in an airtight container for up to 4 days to maintain freshness.

Notes

  • Using parchment paper with overhang makes removing the brownies easier after baking.
  • Do not microwave chocolate on high power to avoid graininess or burning; medium heat in intervals is best.
  • If the flour and cocoa powder are lumpy, sift them to ensure a smooth batter.
  • Cooling the brownies completely improves slicing and texture.
  • You can adjust baking time slightly based on your oven and preferred brownie texture.
