This rich and decadent fusion combines three beloved desserts into one magnificent treat. Slutty Brownies layer chewy chocolate chip cookie dough, classic Oreos, and fudgy brownies for an indulgent dessert that satisfies every sweet craving at once. The combination creates the perfect balance of textures and flavors that will have everyone reaching for seconds.
I first made these for my daughter's slumber party, and they've become our most requested treat for every celebration since. The look on people's faces when they bite into all three layers is absolutely priceless every single time.
Ingredients
- Refrigerated chocolate chip cookie dough: 16oz packages – the convenience factor here is key, and the dough creates the perfect chewy base
- Oreo cookies: classic flavor profile, but feel free to experiment with seasonal varieties for unique variations
- Brownie mix: 18.25 oz box – choose a quality fudgy mix for best results, I prefer the ones labeled extra fudgy
- Eggs: follow your brownie mix instructions, typically adds structure and richness
- Oil: contributes to the moist texture of the brownies
- Water: helps create the perfect brownie consistency
Step-by-Step Instructions
- Prepare the Cookie Dough:
- Allow the refrigerated cookie dough to come to room temperature for 30-60 minutes. This makes it much easier to spread evenly in the pan creating a perfect foundation for your dessert. Preheat your oven to 350°F and thoroughly coat a 9x13 inch baking pan with cooking spray ensuring nothing sticks.
- Create the Cookie Base:
- Press the softened cookie dough into an even layer covering the entire bottom of your prepared pan. Take your time with this step to ensure the thickness is consistent throughout for even baking. The dough should be about ¼ inch thick and reach all corners of the pan.
- Add the Oreo Layer:
- Arrange Oreo cookies in neat rows across the cookie dough base. You will need approximately 24-30 cookies depending on how tightly you place them. Try to create a complete layer without gaps for the best texture and appearance when sliced.
- Top with Brownie Batter:
- Mix the brownie batter according to package directions until smooth and well combined. Carefully pour the batter over the Oreo layer, spreading gently to cover all cookies completely. The brownie layer will be relatively thin, but will rise slightly during baking.
- Bake to Perfection:
- Bake in your preheated oven for 35-45 minutes. The exact time depends on your oven, so start checking at 35 minutes. Insert a toothpick in the center and look for moist crumbs rather than wet batter to indicate doneness. Allow to cool for 10-15 minutes before cutting to achieve clean slices.

My favorite part of making these brownies is watching newcomers take their first bite. My nephew once declared them "the most epic dessert in the universe" which has become our family's official nickname for this recipe.
Storage and Freshness Tips
These decadent bars maintain their freshness for up to 5 days when stored in an airtight container at room temperature. For longer storage, refrigerate for up to a week, though the texture is best within the first few days. You can also freeze individual portions wrapped in plastic and stored in freezer bags for up to 3 months. Allow to thaw at room temperature for about an hour before serving for the best texture experience.
Variations to Try
The beauty of this recipe lies in its flexibility. Try substituting peanut butter cookie dough for the chocolate chip base, or experiment with different Oreo varieties like mint, birthday cake, or limited editions. For a more gourmet version, consider making homemade cookie dough and brownies from scratch. During holidays, incorporate seasonal candies between layers for festive versions that match any celebration theme.

Serving Suggestions
While these brownies are magnificent on their own, elevating them creates an even more impressive dessert. Serve slightly warm with a scoop of vanilla ice cream and a drizzle of hot fudge sauce for an over the top dessert experience. For parties, cut into smaller bite sized pieces and arrange on a platter with fresh berries for color contrast. A light dusting of powdered sugar just before serving adds an elegant touch for special occasions.
