  • Total Time: 40 minutes
  • Yield: 16 servings

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 bean paste
  • 1/2 tsp salt
  • 1/2 cup all purpose flour

Cookies

  • 15 Oreos
  • 5 Oreos (for topping, crushed)

Instructions

  1. Preheat and prepare pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper to prevent sticking and set it aside.
  2. Melt ingredients: In a microwave-safe bowl, combine butter, vegetable oil, granulated sugar, brown sugar, and cocoa powder. Microwave in 30-second intervals, stirring well between each until fully melted. After melting, microwave for an additional 1 minute and stir vigorously to fully dissolve the sugars.
  3. Add eggs and vanilla: Whisk in the eggs one at a time, ensuring each is fully incorporated before adding the next. Then stir in the vanilla bean paste. The batter should be thick enough to pull away from the bowl slightly.
  4. Add dry ingredients: Fold in the all-purpose flour and salt just until the mixture is combined, taking care not to overmix to maintain fudginess.
  5. Layer batter: Pour half of the brownie batter into the prepared baking pan and spread it evenly to cover the bottom.
  6. Add Oreos: Arrange the 15 whole Oreos in the center of the batter layer.
  7. Cover with remaining batter: Pour the remaining brownie batter over the Oreos and spread evenly to fully cover the cookies.
  8. Top with crushed Oreos: Sprinkle the 5 crushed Oreos over the top of the batter for a crunchy, decorative finish.
  9. Bake: Bake the brownies in the preheated oven for 30 minutes. The edges should be set while the center remains fudgy.
  10. Cool and serve: Allow the brownies to cool completely on a wire rack before slicing. This helps achieve the ideal chewy texture and perfect crinkly top slices.

Notes

  • Use cold eggs to help the batter thicken properly.
  • Be careful not to overbake to maintain the fudgy texture.
  • Line the pan with parchment paper for easy removal and clean slicing.
  • The vanilla bean paste enhances flavor over standard vanilla extract.
  • Microwaving the sugar and cocoa mixture helps to melt sugars evenly for smooth batter.
