Equipment

  • Baking Pan
  • Mixing Bowl

Ingredients
  

Cookie Dough Layer

  • ½ cup unsalted butter
  • ½ cup granulated sugar
  • ½ cup brown sugar
  • 1 large egg
  • 1 tsp vanilla extract
  • 1 ¼ cups all-purpose flour
  • ½ tsp baking soda
  • ¼ tsp salt
  • 1 cup semi-sweet chocolate chips

Oreo Layer

  • 12 cookies Oreo cookies classic

Brownie Batter Layer

  • ½ cup unsalted butter
  • 1 cup granulated sugar
  • cup cocoa powder
  • 2 large eggs
  • 1 tsp vanilla extract
  • ¾ cup all-purpose flour
  • ¼ tsp salt

Instructions
 

  • Preheat your oven to 350°F (175°C) and line a baking pan with parchment paper. In a mixing bowl, cream together unsalted butter, granulated sugar, and brown sugar until light and fluffy. Add one large egg and vanilla extract, then mix in all-purpose flour, baking soda, and salt. Fold in chocolate chips and press the dough evenly into the pan.
  • Place 12 whole Oreo cookies in a single layer on top of the cookie dough, ensuring they do not overlap.
  • In a separate bowl, melt unsalted butter and whisk in granulated sugar and cocoa powder until smooth. Allow the mixture to cool slightly, then mix in 2 large eggs and vanilla extract, and finally fold in all-purpose flour and salt.
  • Pour the brownie batter evenly over the Oreo layer, using a spatula to smooth the top and ensure full coverage.
  • Bake in a preheated oven for 30 to 35 minutes until a toothpick inserted in the center comes out with a few moist crumbs. Let cool completely before slicing.
