  • 120 g unsalted butter used for melting with chocolate
  • 3 large eggs room temperature for emulsification
  • 150 g granulated sugar creates structure in brownies

  • 33 g cocoa powder unsweetened, Dutch-processed preferred
  • 90 g all-purpose flour gives body without drying
  • ¼ teaspoon salt enhances chocolate flavor
  • 16 Oreo cookies whole, classic variety for crunch

Equipment

  • 1 Digital oven thermometer helps verify accurate oven temperature for even baking
  • 1 Digital kitchen scale ensures precise ingredient measurements for consistent results
  • 1 Electric hand mixer used to cream butter and sugars and whip eggs until fluffy
  • 1 Rubber spatula ideal for gently folding batters without deflating them
  • 1 Offset spatula allows smooth, even spreading of layers in the pan
  • 1 9-inch square brownie pan provides the correct thickness so all layers bake evenly

Method
 

  1. Preheat the oven to 175°C / 350°F and lightly grease a square baking pan, then line it with parchment paper.
  2. Beat the softened butter with both sugars until pale and fluffy using an electric mixer.
  3. Blend in the egg and vanilla until fully incorporated.
  4. Sift the flour, baking soda, and salt into the bowl and gently fold until no dry streaks remain.
  5. Stir in the chocolate chips evenly through the dough.
  6. Press the cookie dough evenly into the prepared pan and smooth the surface.
  7. Place the Oreo cookies in a single layer on top of the dough and refrigerate the pan while preparing the brownie batter.
  8. Melt the butter and dark chocolate together gently until smooth, then let it cool slightly.
  9. Whip the eggs with both sugars until the mixture becomes pale and thick.
  10. Slowly mix the melted chocolate into the egg mixture on low speed until combined.
  11. Sift in the flour, cocoa powder, and salt, folding gently just until incorporated.
  12. Pour the brownie batter over the Oreo layer and smooth it evenly.
  13. Bake until the edges are set and the center remains slightly soft, then remove from the oven.
  14. Allow the brownies to cool completely in the pan before slicing.
