Ingredients

Units Scale

Wet Ingredients

  • 2/3 cup butter
  • 1/4 cup vegetable oil
  • 1 cup granulated sugar
  • 1/3 cup brown sugar
  • 2 cold eggs
  • 1 tsp vanilla extract

Dry Ingredients

  • 2/3 cup cocoa powder
  • 1/2 cup all purpose flour
  • 1/2 tsp salt

Additional

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

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper and set it aside for easy removal of the brownies later.
  2. Melt Butter and Sugars: In a microwave-safe bowl, combine the butter, vegetable oil, granulated sugar, and brown sugar. Microwave in 30-second intervals, stirring in between, until fully melted and combined. After fully melted, microwave an additional 1 minute and stir vigorously to ensure the sugars dissolve completely. Using a hand or stand mixer at this stage yields the best results for a smooth texture.
  3. Add Eggs and Vanilla: Whisk in the eggs one at a time to the warm sugar mixture, ensuring each is fully incorporated before adding the next. Then stir in the vanilla extract. The batter should be slightly thick and pull away from the sides of the bowl.
  4. Combine Dry Ingredients: Add the cocoa powder, all-purpose flour, and salt to the wet ingredients. Gently fold everything together just until combined, taking care not to overmix to maintain a tender brownie texture.
  5. Layer the Batter and Oreos: Pour half of the brownie batter into the prepared baking pan and spread it evenly. Arrange the 15 whole Oreos in the center over the batter in a single layer. Top with the remaining batter and spread carefully to cover the Oreos completely.
  6. Add Crushed Oreos and Bake: Sprinkle the 5 crushed Oreos evenly over the top of the batter. Place the baking pan in the preheated oven and bake for 30 minutes, or until a toothpick inserted near the edges comes out with moist crumbs but no wet batter.
  7. Cool and Serve: Remove the brownies from the oven and allow them to cool completely on a wire rack to set. Once cooled, slice into 16 squares for perfectly crinkled tops and gooey Oreo-stuffed centers.

Notes

  • For an extra fudgy texture, avoid overmixing the batter once the flour is added.
  • Allow the brownies to cool fully before slicing to prevent crumbling and maintain clean cuts.
  • You can substitute regular Oreos with any flavored variety to customize your brownies.
  • Storing brownies in an airtight container at room temperature keeps them fresh for up to 3 days.
  • For thicker brownies, use a smaller baking pan or increase the baking time slightly, checking periodically.
