Make these homemade Oreo brownies from scratch for a rich, dense, and chewy chocolate dessert. This simple recipe delivers a perfect fudgy texture and a desirable shiny, crackly top.

Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter
  • 1 1/4 cups granulated sugar
  • 1 cup packed light brown sugar
  • 4 large eggs
  • 1 tablespoon vanilla extract
  • 3/4 cup unsweetened cocoa powder
  • 1 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1/2 cup all-purpose flour
  • 1 cup semi-sweet chocolate chips
  • 12 Oreo cookies, roughly chopped

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×9 inch metal baking pan with parchment paper, leaving an overhang on two sides for easy removal. Lightly grease the paper.
  2. In a medium saucepan, melt the butter over low heat. Remove from heat once melted.
  3. Whisk the granulated sugar and brown sugar into the melted butter until fully combined. This step helps create the shiny top.
  4. Add the eggs one at a time, whisking well after each addition until the mixture is smooth and glossy. Whisk in the vanilla extract.
  5. In a separate bowl, whisk together the cocoa powder, salt, and baking powder. Add this dry mixture to the wet ingredients and mix until just combined. Do not overmix.
  6. Gently fold in the flour and the chocolate chips.
  7. Pour half of the brownie batter into the prepared pan and spread evenly. Sprinkle half of the chopped Oreo cookies over the batter.
  8. Pour the remaining batter over the cookies and top with the remaining chopped Oreos. Gently press the top Oreos slightly into the batter.
  9. Bake for 30 to 35 minutes. A toothpick inserted near the center should come out with moist crumbs attached, not wet batter, 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.
  11. Cut into squares and serve.

Notes

  • For the best shiny, crackly top, ensure you whisk the sugar and melted butter thoroughly before adding the eggs.
  • Use room temperature eggs for better incorporation into the batter.
  • If you prefer a thicker, chewier brownie, use a slightly smaller 8×8 inch pan.
  • You can substitute regular Oreos with Mint Oreos for a different flavor profile.
