Ingredients

Brownie Batter

  • 2/3 cup butter
  • 1/4 cup vegetable oil
  • 1 cup granulated sugar
  • 1/3 cup brown sugar
  • 2/3 cup cocoa powder
  • 2 eggs (cold)
  • 1 tsp vanilla extract
  • 1/2 tsp salt
  • 1/2 cup all purpose flour

Oreo Center and Topping

  • 15 Oreos (whole or halved for the center)
  • 5 Oreos (crushed for topping)

Instructions

  1. Preheat and Prep: Preheat your oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper and set aside to prevent sticking and ensure easy removal.
  2. Melt and Mix Sugars: In a microwave-safe bowl, combine the butter, vegetable oil, granulated sugar, and brown sugar. Microwave in 30-second intervals, stirring between each until the mixture is fully melted. Then microwave for an additional 1 minute and stir vigorously to dissolve the sugar completely, which helps achieve a shiny crinkle top on the brownies.
  3. Add Eggs and Vanilla: Whisk in the cold eggs one at a time to fully incorporate, then stir in the vanilla extract. The batter should become glossy and start pulling away slightly from the bowl edges.
  4. Combine Dry Ingredients: Add the cocoa powder, all purpose flour, and salt to the wet mixture. Fold everything together gently until just combined to avoid overmixing and maintain the fudgy texture.
  5. Layer Batter and Oreos: Pour half of the brownie batter into the lined pan and spread evenly. Arrange the 15 whole or halved Oreos in a single layer over the batter. Pour the remaining batter on top and spread to cover the Oreos completely.
  6. Add Crushed Oreo Topping: Sprinkle the 5 crushed Oreos evenly over the top layer of batter for added texture and flavor.
  7. Bake: Place the pan in the preheated oven and bake for 30 minutes. Bake until the tops are set but still moist in the center – a toothpick inserted should come out with a few moist crumbs.
  8. Cool and Serve: Allow the brownies to cool completely on a wire rack for several hours (ideally 8 hours) before cutting. This cooling time ensures the Oreo layer sets and your slices remain clean and crinkle-topped. For clean cuts, dip a sharp knife in hot water and dry it before slicing.

Notes

  • Allow the brownies to cool completely on a wire rack before slicing to avoid smearing the Oreo layer.
  • The extra minute microwaving and vigorous stirring of the sugar mixture helps achieve the signature shiny crinkle top.
  • Use regular Oreos for the best texture; Halloween Oreos work well and avoid Double Stuf.
  • For the cleanest cuts, dip a knife in hot water between slices.
  • Store brownies airtight at room temperature for up to 5 days, or wrap tightly and freeze for up to 3 months.
