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
- 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.
- 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.
- 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.
- 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.
- Layer batter: Pour half of the brownie batter into the prepared baking pan and spread it evenly to cover the bottom.
- Add Oreos: Arrange the 15 whole Oreos in the center of the batter layer.
- Cover with remaining batter: Pour the remaining brownie batter over the Oreos and spread evenly to fully cover the cookies.
- Top with crushed Oreos: Sprinkle the 5 crushed Oreos over the top of the batter for a crunchy, decorative finish.
- Bake: Bake the brownies in the preheated oven for 30 minutes. The edges should be set while the center remains fudgy.
- 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.
