Gather all your ingredients for a wonderful baking experience.

Directions

  1. Preheat the oven to 350°F (180°C). Lightly grease a 9×13 inch (23×33 cm) baking pan, then line with parchment paper, allowing an overhang on the sides for easier removal later. Greasing the pan first helps the paper stick. You can also skip the parchment and just grease the pan if preferred.
  2. Chocolate Chip Cookie Layer: In a large bowl, cream together the softened butter, brown sugar, and white sugar until light and fluffy. Beat in the egg, egg yolk, and vanilla extract until smooth. Gradually mix in the flour and salt, followed by the chocolate chips.
  3. Press half of the chocolate chip cookie dough evenly into the bottom of the prepared pan.
  4. Oreo Layer: Layer the Oreo cookies on top of the first layer of cookie dough in a single, even row.
  5. Brownie Batter: In a medium saucepan, melt the cubed butter and dark chocolate together over low heat, stirring until smooth. Remove from heat and stir in the granulated sugar, then add the eggs one at a time, mixing well after each addition. Sift in the flour, cocoa powder, and salt, stirring until just combined.
  6. Pour the brownie batter over the Oreos, spreading it evenly.
  7. Top with the remaining chocolate chip cookie dough, dropping spoonfuls over the brownie layer and spreading gently.
  8. Bake for 30-35 minutes or until a toothpick inserted in the center comes out with a few moist crumbs but not wet batter. Cool in the pan for at least 15 minutes before using the parchment overhang to lift them out for further cooling.

Tips & Variations

  • Ingredient substitutions: You can substitute the unsalted butter with coconut oil for a dairy-free option. Gluten-free all-purpose flour can replace regular flour for a gluten-free version.
  • Optional variations: Add chopped nuts, such as walnuts or pecans, to the brownie batter for added crunch. For a minty twist, try using mint Oreos instead!
  • Storage or reheating tips: Store leftover brownies in an airtight container at room temperature for up to three days, or refrigerate for longer-lasting freshness. To reheat, simply pop a brownie in the microwave for about 10 seconds.
