Create the best Oreo brownie recipe with this guide for rich, fudgy cookies and cream brownies that feature a perfect, shiny, crackly top. This simple dessert recipe delivers indulgent baking.

Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, melted
  • 2 cups granulated sugar
  • 1 cup packed light brown sugar
  • 4 large eggs, room temperature
  • 1 tablespoon vanilla extract
  • 1 cup all-purpose flour
  • ¾ cup unsweetened cocoa powder, good quality
  • 1 teaspoon salt
  • ½ teaspoon baking powder
  • 1 cup semi-sweet chocolate chips
  • 12 whole Oreo cookies, roughly chopped
  • 1 cup Oreo cookie pieces (for mixing in)

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 only until just combined. Do not overmix.
  6. Gently fold in the chocolate chips and the 1 cup of roughly chopped Oreo cookies.
  7. Pour half of the batter into the prepared pan and spread evenly.
  8. Arrange the 12 whole Oreo cookies evenly over the batter layer. Sprinkle the remaining 1 cup of Oreo pieces over the whole cookies.
  9. Carefully spoon the remaining batter over the top, gently spreading it to cover the cookies as much as possible.
  10. Bake for 30 to 35 minutes. The edges should look set, and a toothpick inserted near the center should come out with moist, fudgy crumbs attached, not wet batter. This ensures you get fudgy style brownies.
  11. Let the brownies cool completely in the pan on a wire rack before lifting them out using the parchment paper overhang.
  12. Once cool, cut into squares. Enjoy your decadent chocolate bars.

Notes

  • For the best crackly top, do not overbake. The residual heat will continue to cook them as they cool.
  • Use high-quality cocoa powder for the richest chocolate flavor in these rich chocolate treats.
  • If you prefer a layered brownie, you can press half the batter into the pan, bake for 15 minutes, then top with the Oreos and remaining batter.
