Ingredients
  

  • For the Cookie Dough:
  • 6 tablespoons 84g Unsalted Butter, softened
  • ½ cup 100g Light Brown Sugar, packed
  • 1/8 cup 25g Granulated Sugar
  • 1 large Egg Yolk room temperature
  • 1 teaspoon Vanilla Extract
  • ¾ cup + 2 tablespoons 107g All-Purpose Flour
  • ½ teaspoon Fine Sea Salt
  • ½ teaspoon Baking Soda
  • 4 Oreo Cookies roughly chopped
  • For the Brownie Batter:
  • 4 tablespoons 54g Unsalted Butter
  • 1/3 cup 75g Semi-Sweet Chocolate Chips
  • ¼ cup + 1/8 cup 80g Granulated Sugar
  • 1 large Egg room temperature
  • 1 teaspoon Vanilla Extract
  • ¼ cup 20g Unsweetened Cocoa Powder
  • ¼ cup 35g All-Purpose Flour
  • ¼ teaspoon Fine Sea Salt

Instructions
 

  • Preheat the oven and line a square baking pan with parchment paper, leaving an overhang on the sides for easy lifting.
  • In a large bowl, cream together the softened butter and both sugars until the mixture is light and fluffy.
  • Add the egg yolk and vanilla to the cookie mixture, then fold in the dry ingredients and chopped Oreos until a dough forms.
  • Melt the butter and chocolate chips together for the brownie layer and allow the mixture to cool slightly.
  • Whisk the sugar, whole egg, and vanilla vigorously until frothy, then stream in the melted chocolate.
  • Sift the cocoa powder, flour, and salt into the chocolate mixture and fold gently until just combined.
  • Drop mounds of cookie dough and scoops of brownie batter into the pan, pressing them down to create an even layer.
  • Top the batter with extra crushed Oreo pieces for added texture and visual appeal.
  • Bake until the edges are set and the cookie portions are golden brown, then cool completely in the pan before slicing.

Notes

• Temperature Matters: Ensure eggs and butter are at room temperature to prevent the batter from breaking.
• The Foil Method: Cover the pan with foil if the cookie dough tops brown too quickly before the brownies are finished.
• Clean Slices: For the best results, chill the bars before cutting with a sharp, clean knife
