Ingredients
- For the Cookie Layer:
- 1 cup (2 sticks) unsalted butter, softened
- 1 cup granulated sugar
- 1 cup light brown sugar, packed
- 2 large eggs
- 2 tsp vanilla extract
- 2 ½ cups all-purpose flour
- 1 tsp baking soda
- ½ tsp salt
- 2 cups semi-sweet chocolate chips
- For the Oreo Layer:
- 24 Oreo cookies (or enough to form an even layer in your pan)
- For the Brownie Layer:
- 1 cup unsalted butter
- 8 oz semi-sweet chocolate, chopped
- 1 ½ cups granulated sugar
- 1 cup light brown sugar, packed
- 4 large eggs
- 2 tsp vanilla extract
- 1 cup all-purpose flour
- ½ cup cocoa powder
- ½ tsp salt
Step-by-Step Instructions
- Preheat the Oven: Preheat your oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper, leaving some overhang for easy removal. Lightly grease the parchment paper.
- Prepare the Cookie Dough Layer: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until fluffy and smooth, about 2–3 minutes. Beat in the eggs one at a time, then add the vanilla extract. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined. Fold in the chocolate chips. Spread the cookie dough evenly over the bottom of your prepared pan.
- Add the Oreo Layer: Place a layer of Oreo cookies directly on top of the cookie dough. Make sure to cover as much of the surface as possible; slight gaps between cookies are okay, as the brownie layer will fill in the spaces.
- Prepare the Brownie Batter: In a medium saucepan, melt the butter and chopped chocolate over low heat, stirring constantly until smooth. Remove from heat, allowing it to cool slightly. In a large bowl, whisk together the granulated sugar, brown sugar, eggs, and vanilla extract. Slowly add the melted chocolate mixture, whisking continuously. Sift in the flour, cocoa powder, and salt, stirring until just combined.
- Assemble the Brownies: Pour the brownie batter over the Oreo layer, spreading it evenly to cover all the cookies. Smooth the top with a spatula.
- Bake: Bake in the preheated oven for 35–40 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs (avoid overbaking for fudgier brownies).
- Cool and Serve: Allow the brownies to cool completely in the pan, which will take about 1 hour. For clean slices, refrigerate the brownies for an additional 30 minutes before cutting. Use the parchment paper overhang to lift the brownies from the pan, then slice into squares and enjoy.
Ingredient Background
Each ingredient in these Slutty Brownies plays a crucial role in creating the perfect texture and flavor. The combination of brown and white sugars in the cookie layer adds chewiness and sweetness, while the chocolate chips provide melty pockets of flavor. Oreos act as a crunchy, creamy middle layer, adding an extra dimension to the dessert. In the brownie layer, the use of both cocoa powder and melted chocolate ensures deep chocolate flavor and a fudgy texture, perfect for contrasting the cookie layer beneath.
Technique Tips
- Creaming Butter and Sugar: Properly creaming the butter and sugars for the cookie layer helps achieve a soft, chewy base. Beat until the mixture is light and fluffy, about 2–3 minutes.
- Melting Chocolate: When melting the chocolate for the brownie layer, stir frequently and remove from heat once melted to avoid burning.
- Layering for Success: Be careful when spreading the brownie layer over the Oreos, as too much force can disrupt the cookie layer. Using a spatula or an offset spreader will help you gently distribute the batter evenly.
Alternative Presentation Ideas
- Mini Slutty Brownie Bites: Prepare the recipe in a muffin tin for individual servings. Simply layer a spoonful of cookie dough, one Oreo, and top with brownie batter. Reduce baking time to 20–25 minutes.
- Slutty Brownie Sundae: Serve warm brownie squares with a scoop of vanilla ice cream, a drizzle of chocolate syrup, and a sprinkle of crushed Oreos.
- Layered Trifle: Cut the baked brownies into small cubes and layer them with whipped cream, chocolate pudding, and Oreo crumbs in a trifle bowl. Perfect for a larger crowd!
Additional Tips for Success
- Room Temperature Ingredients: Ensuring that ingredients like butter and eggs are at room temperature helps with smooth mixing and consistent texture.
- Lining the Pan: Use parchment paper with overhang for easy removal of the brownies, especially useful when slicing them for presentation.
- Avoid Overbaking: To keep the brownie layer gooey, start checking the brownies at the 35-minute mark. Insert a toothpick into the brownie layer only to avoid overcooking.
Recipe Variations
- Peanut Butter Lovers: Add a layer of peanut butter cups between the Oreo and brownie layers for a nutty twist.
- Mint Chocolate Slutty Brownies: Use mint-flavored Oreos and add a dash of peppermint extract to the brownie layer for a refreshing flavor.
- Salted Caramel: Drizzle caramel sauce over the Oreo layer before adding the brownie batter. Top the finished brownies with a sprinkle of flaky sea salt.
- Gluten-Free: Substitute a gluten-free flour blend for the all-purpose flour in both the cookie and brownie layers. Ensure the Oreos are also gluten-free.
Freezing and Storage
- Storage: Store leftover brownies in an airtight container at room temperature for up to 3 days. To keep them fresh longer, refrigerate for up to 7 days.
- Freezing: For longer storage, freeze individual brownies in a single layer on a baking sheet until firm, then transfer to a freezer-safe bag. They’ll keep in the freezer for up to 3 months. To serve, thaw brownies at room temperature for an hour or reheat in the microwave for 15–20 seconds.
Healthier Twist Ideas
- Reduce Sugar: Use dark chocolate instead of semi-sweet in the brownie layer, and try reducing the sugar by ¼ cup in the cookie layer.
- Whole-Wheat Flour: Substitute half of the all-purpose flour in the cookie and brownie layers with whole-wheat flour for added fiber and nutrients.
- Add Nuts: Incorporate walnuts or pecans in the brownie layer for healthy fats and added crunch.
- Lower-Fat Option: Replace half the butter with unsweetened applesauce in the brownie layer to reduce the fat content while keeping the brownies moist.
Serving Suggestions for Events
- Birthday Parties: Arrange the brownies on a platter with sparklers for a celebratory display.
- Holiday Gatherings: Serve with peppermint or gingerbread-flavored whipped cream for a seasonal twist.
- Game Nights: Make mini brownie bites in a muffin tin for easy snacking during the game.
- Potlucks: Present the brownies in cupcake liners for a convenient grab-and-go option.
Special Equipment
- 9×13-inch Baking Pan: A sturdy, metal or glass baking pan is essential for even baking.
- Parchment Paper: Using parchment with overhang makes removing and slicing the brownies easier.
- Offset Spatula: Helpful for spreading the cookie dough and brownie batter smoothly.
