Build Slutty Brownies One Layer at a Time

  • Prep Your Baking Arena

Grab a 9×9-inch baking dish and line it with parchment paper, giving it a quick spray of cooking oil to prevent sticking.

  • Create Chocolate Chip Cookie Foundation

Spread the chocolate chip cookie dough evenly across the bottom of the pan, creating a smooth, delicious base layer.

  • Add Oreo Cookie Blanket

Gently place Oreo cookies in a single layer directly on top of the cookie dough, covering the entire surface.

  • Pour Brownie Batter Finale

Carefully pour the rich, decadent brownie batter over the Oreo layer, ensuring complete coverage and smooth distribution.

  • Bake to Gooey Perfection

Slide the pan into a preheated 350°F oven and bake for 30-35 minutes. Look for slightly crisp edges and a soft center that sets when cooled.

  • Cool and Slice

Allow the brownies to cool completely in the pan, then lift out the parchment paper and cut into tantalizing squares of layered deliciousness.

Tips and Tweaks for Ultimate Slutty Brownies

  • Cookie Dough Base Perfection: Press the chocolate chip cookie dough evenly and gently into the pan to create a uniform layer that bakes consistently.
  • Oreo Layer Placement: Arrange Oreo cookies in a single, tight layer without overlapping to ensure complete cookie coverage and delicious texture in every bite.
  • Brownie Batter Balance: Pour brownie batter slowly and carefully over the Oreo layer, using a spatula to spread it evenly without disturbing the cookie layer underneath.
  • Gluten-Free Adaptation: Replace regular chocolate chip cookie dough and Oreos with gluten-free alternatives to make this dessert suitable for those with gluten sensitivities.
  • Make-Ahead Magic: Prepare the entire dessert in advance and refrigerate before baking, which can help set the layers and intensify the flavors for an even more decadent treat.

Serve Slutty Brownies for Any Crowd

  • Chocolate Chip Cookie Delight: Serve these brownies warm with a scoop of vanilla ice cream for a heavenly contrast of temperatures and textures that melts in your mouth.
  • Party Platter Perfection: Cut into bite-sized squares and arrange on a decorative platter for an eye-catching dessert that's perfect for gatherings, potlucks, or game night celebrations.
  • Decadent Drizzle Option: Enhance the richness by adding a light drizzle of caramel sauce or melted chocolate on top, creating an extra layer of indulgence that makes each bite more luxurious and special.
  • Midnight Snack Magic: Enjoy these brownies slightly chilled from the refrigerator for a fudgy, dense treat that's equally delicious when served cold, making them an irresistible late-night indulgence.

Store Slutty Brownies Without Losing Texture

  • Quick Refrigeration Strategy: Store these decadent brownies in an airtight container within the refrigerator for up to 5 days, maintaining their rich moisture and delectable texture.
  • Make-Ahead Magic: Prepare the entire dessert in advance and freeze uncut for maximum convenience, wrapping tightly in plastic wrap and aluminum foil to prevent freezer burn.
  • Room Temperature Tip: Let brownies sit at ambient temperature for 15-20 minutes before serving to enhance their soft, gooey consistency and maximize flavor development.
  • Portion Control Trick: Cut brownies into individual squares and separate layers with wax paper when storing, preventing them from sticking together and making grab-and-go snacking easier.

Ingredients

Scale
  • 16 oreo cookies (double-stuffed)
  • 1 cup granulated sugar
  • ½ cup brown sugar (packed)
  • 1 cup (2 sticks) unsalted butter (½ cup softened, ½ cup melted)
  • 3 large eggs
  • 1 ¾ cups all-purpose flour
  • ⅓ cup unsweetened cocoa powder
  • ½ cup semi-sweet chocolate chips
  • 2 tsp vanilla extract
  • ½ tsp baking soda
  • ½ tsp baking powder
  • ½ tsp salt

Instructions

  1. Preheat: Warm the oven to 350°F, establishing the perfect thermal environment for these luxurious layered brownies.
  2. Pan Preparation: Line a baking dish with parchment paper, creating an overhang for effortless removal and lightly coating with cooking spray to prevent adhesion.
  3. Cookie Foundation: Spread chocolate chip cookie dough uniformly across the pan’s base, creating a robust and flavorful initial layer that will anchor the entire dessert.
  4. Cookie Placement: Systematically arrange chocolate sandwich cookies atop the cookie dough, ensuring complete coverage to generate a delightful textural contrast.
  5. Brownie Topping: Delicately pour brownie batter over the cookie layer, gently distributing it to guarantee comprehensive and consistent coverage of the underlying components.
  6. Baking Process: Position the assembled dish centrally in the preheated oven and bake for 30-35 minutes, monitoring until edges are solidified while maintaining a luscious, fudgy center.
  7. Cooling and Serving: Allow the dessert to cool completely within the pan, enabling layers to stabilize, then utilize parchment paper edges to extract and slice into decadent squares of pure culinary indulgence.

Notes

  • Prevent Cookie Spreading: Chill cookie dough before layering to maintain clean, defined layers and prevent excessive spreading during baking.
  • Check Brownie Doneness: Insert a toothpick near the edge – it should come out with a few moist crumbs, ensuring a perfectly fudgy texture without being undercooked.
  • Handle with Care: Let brownies cool completely before cutting to prevent crumbling and maintain the intricate layered structure of the dessert.
  • Customize Dietary Needs: Substitute gluten-free cookie dough and sandwich cookies, use dairy-free chocolate, and swap eggs with flax eggs for vegan-friendly version.
