Ingredients
Scale
- 1/2 cup unsalted butter, melted
- 1 cup granulated sugar
- 2 large eggs, room temperature
- 1 teaspoon pure vanilla extract
- 1/3 cup high-quality cocoa powder (unsweetened)
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt
- 1/4 teaspoon baking powder
- 16–20 Oreo cookies (Standard or Double Stuf)
- 1/2 cup semi-sweet chocolate chips (optional for extra fudginess)
Instructions
- Start by preheating your oven to 350°F (175°C). Line an 8×8 inch square baking pan with parchment paper, leaving an overhang on the sides. This “sling” method allows you to lift the brownies out easily once they have cooled. Lightly grease the parchment paper with butter or non-stick cooking spray to ensure nothing sticks.
- In a large mixing bowl, whisk together the melted butter and granulated sugar until well combined. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract. In a separate bowl, sift together the cocoa powder, flour, salt, and baking powder. Gradually fold the dry ingredients into the wet ingredients using a spatula. Mix only until the flour streaks disappear; overmixing will lead to a cake-like texture rather than a fudgy one.
- Spread about half of the brownie batter into the bottom of your prepared pan. Smooth it out into an even layer. Place the Oreo cookies in rows on top of the batter, pressing them down slightly so they stay in place. Pour the remaining batter over the cookies, using a spatula to gently spread it to the edges until all the Oreos are completely covered. Sprinkle chocolate chips on top if desired. Bake for 25 to 30 minutes. A toothpick inserted into the center should come out with a few moist crumbs, but not raw batter.
- Remove the pan from the oven and place it on a wire rack. Let the brownies cool completely in the pan for at least 1 hour. This waiting period is crucial because the fudgy structure sets as it cools. Once cold, use the parchment overhang to lift the entire block out of the pan. Use a sharp, warm knife to slice into 16 squares, ensuring you cut through the center of the Oreos for a beautiful cross-section.
