  • ½ cup Brown sugar - Packed
  • ¼ cup White sugar
  • 1 large Egg - Room temp
  • 1 teaspoon Vanilla extract
  • 1 ¼ cups All-purpose flour

  • 1 cup Sugar
  • 2 large Eggs - Room temp
  • 1 teaspoon Vanilla extract

  • ¼ teaspoon Salt

Instructions 

Make the Cookie Base

  • Cream butter and sugars until fluffy.
  • Add egg and vanilla, mixing well.
  • Stir in flour, baking soda, and salt until just combined.
  • Fold in chocolate chips.
  • Press dough into a parchment-lined 9x13 pan.
  • Chill in the fridge while preparing the next layer.

Add the Oreo Layer

  • Arrange Oreos evenly over the cookie dough.
  • Leave small gaps but don’t overlap.

Prepare the Brownie Layer

  • Melt chocolate and butter together until smooth.
  • Whisk in sugar, eggs, and vanilla.
  • Sift in cocoa powder, flour, and salt, stirring gently.
  • Pour brownie batter over the Oreo layer and spread evenly.

Bake to Perfection

  • Preheat oven to 350°F (175°C).
  • Bake on the center rack for 30-35 minutes.
  • Insert a toothpick in the center—moist crumbs are okay.

Cool & Slice

  • Let brownies cool completely before cutting.
  • For cleaner slices, use a hot knife.
