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
  • 3/4 cup all-purpose flour
  • 1 cup semi-sweet chocolate chips
  • 1 package (about 14.3 ounces) Oreo cookies, whole
  • 1/2 cup crushed Oreo cookies for topping

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 medium saucepan over low heat, melt the butter. Remove from heat.
  3. Whisk the granulated sugar and brown sugar into the melted butter until combined.
  4. Whisk in the eggs one at a time until fully incorporated. Stir 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 chocolate chips.
  7. Spread half of the brownie batter evenly into the prepared pan.
  8. Arrange the whole Oreo cookies in a single layer over the batter.
  9. Spoon the remaining brownie batter over the Oreos, gently spreading to cover them as much as possible.
  10. Sprinkle the crushed Oreo cookies evenly over the top layer of batter.
  11. Bake for 30 to 35 minutes. The edges should look set, and a toothpick inserted near the center should come out with moist crumbs attached, not wet batter, for a fudgy texture.
  12. Let the brownies cool completely in the pan on a wire rack. Cooling is essential for achieving clean slices and the best texture.
  13. Once cool, use the parchment paper overhang to lift the brownies out of the pan. Slice into squares.

Notes

  • For the best shiny, crackly top, do not overbake the brownies. The residual heat will finish cooking them as they cool.
  • You can make these brownies ahead of time; they store well in an airtight container at room temperature for up to four days.
  • If you prefer a gooey brownie, reduce the baking time by 3 to 5 minutes.
