Total Time 1 hour 35 minutes
Servings 9 brownies

Ingredients
  

  • ½ cup brown butter 113 g, cooled but fluid
  • ½ cup brown sugar 100 g
  • ½ cup granulated sugar 100 g
  • 2 large eggs
  • 1 tsp vanilla extract 4.2 g
  • ½ cup all-purpose flour 60 g
  • ½ cup cocoa powder 40 g
  • ¼ tsp fine salt 1.5 g
  • ¼ tsp baking soda 1.25 g
  • 8 Oreo cookies 5 crushed for batter, 3 for topping
  • ¼ cup chocolate chips 45 g

Instructions
 

  • Preheat oven to 350°F (175°C). Line an 8×8-inch metal pan with parchment.
  • Whisk together brown butter, brown sugar, and granulated sugar until glossy.
  • Whisk in eggs and vanilla until slightly thickened.
  • Sift in flour, cocoa, salt, and baking soda. Fold gently until combined.
  • Fold in chocolate chips and 5 crushed Oreos.
  • Spread batter into pan, top with remaining 3 Oreos (broken into chunks).
  • Bake 25–35 minutes until edges are set and a toothpick comes out with moist crumbs.
  • Cool before slicing.

Notes

  • Whisking the eggs and sugars well helps create a shiny top.
  • Start checking for doneness early; brownies continue to cook as they cool.
  • Store airtight for 2–4 days or freeze for up to 2 months.
  • For extra gooeyness, swap some chips for chopped dark chocolate.
