Make these rich, decadent Oreo brownies that feature a fudgy center and a beautiful, crackly top. This simple recipe delivers bakery-style results using common ingredients.

Ingredients

Scale
  • 1 cup (226g) unsalted butter, melted
  • 2 cups (400g) granulated sugar
  • 1 cup (200g) packed light brown sugar
  • 4 large eggs, room temperature
  • 1 tablespoon vanilla extract
  • 1 cup (120g) all-purpose flour
  • ¾ cup (65g) unsweetened cocoa powder
  • 1 teaspoon salt
  • ½ teaspoon baking powder
  • 1 cup (170g) semi-sweet chocolate chips
  • 12 Oreo cookies, roughly chopped

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Lightly grease the paper.
  2. In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until fully combined.
  3. Whisk in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  4. In a separate medium bowl, whisk together the flour, cocoa powder, salt, and baking powder.
  5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed or by hand until just combined. Do not overmix.
  6. Stir in the chocolate chips.
  7. Gently fold in about two-thirds of the chopped Oreo cookies.
  8. Pour the batter into the prepared pan and spread evenly. Sprinkle the remaining chopped Oreos over the top of the batter.
  9. Bake for 30 to 35 minutes. A toothpick inserted near the edge should come out with moist crumbs, but the center should still look slightly underdone for a fudgy texture.
  10. Let the brownies cool completely in the pan on a wire rack before lifting them out using the parchment overhang. Cut into squares.

Notes

  • For the best shiny, crinkly top, do not overmix the batter after adding the flour. The sugar needs to dissolve properly during mixing.
  • Use room temperature eggs for better emulsification, which helps create that desirable shiny crust.
  • If you prefer a thicker, more cake-like brownie, bake for an additional 5 to 7 minutes.
  • This recipe makes excellent cookies and cream brownies.
