Every time I bake a pan of these Slutty Brownies, my whole kitchen smells like pure chocolate heaven. Layers of fudgy brownie, gooey cookie dough, and Oreo cookies come together into one over-the-top dessert that’s outrageously rich and unbelievably easy to make. They’re the kind of treat that disappears fast, no matter the crowd or occasion.
If you’re thinking about making Slutty Brownies do it! This is the recipe for you. I’ve tested and perfected the layers so the cookie base stays chewy, the Oreos keep their crunch, and the brownie topping bakes up fudgy and rich. You don’t need any fancy ingredients or extra steps. Just a few simple shortcuts that make these come out perfect every single time. I promise, one bite and you’ll understand why everyone asks for the recipe
If you love over-the-top desserts like these brownies, you’ve got to try my Rolo Brownies and my Reese’s Fudge. They are both ridiculously easy and just as irresistible.
Ingredients Notes
See the recipe card for full information on ingredients and quantities.
- Refrigerated chocolate chip cookie dough: I use Nestle Toll House Chocolate Chip Lovers cookie dough, but you can use any store-bought brand or use homemade if you prefer.
- Oreo cookies: I use classic or Double Stuffed Oreos, but any flavor will add a fun twist!
- Brownie mix (plus egg, oil, and water called for on box): Betty Crocker Supreme Triple Chunk is my go-to, but any brand will work. You can also use a homemade recipe if you like.
Recipe Variations
Once you’ve made the classic version, it’s fun to mix things up:
- Peanut Butter Lovers: Use peanut butter cookie dough and Reese’s Peanut Butter Cup Oreos.
- Holiday Twist: Swap in seasonal Oreos or add M&M’s to the brownie mix.
- Extra Chocolate: Stir in a handful of chocolate chips to the brownie batter before baking.
- Gluten-Free Option: Use gluten-free brownie mix and Oreos to make this dessert safe for everyone.
How to Make Slutty Brownies
These brownies are ridiculously easy to make. You’ll have three delicious layers ready for the oven in just minutes.
Step 1
Preheat your oven to 350°F and line a 9×9-inch pan with parchment paper or foil. Spray lightly with nonstick spray.
Step 2
Press the cookie dough evenly into the bottom of the pan to form the first layer.
Step 3
Arrange the Oreos in a single layer on top of the cookie dough.
Step 4
Prepare the brownie mix according to the package directions, then pour it evenly over the Oreos.
Step 5
Bake for about 35–40 minutes, or until the brownies are set and a toothpick inserted in the center comes out mostly clean.
Cool completely before cutting. The layers will set as they cool, giving you perfect slices.
Storage Instructions
- Make Ahead: These brownies are great for prepping ahead! Bake, cool completely, and store covered at room temperature until ready to serve.
- To Store: Keep leftovers in an airtight container at room temperature for up to 4 days.
- To Freeze: Wrap individual brownies tightly in plastic wrap and place them in a freezer-safe bag for up to 3 months. Thaw at room temperature before serving.

Slutty Brownies
Ingredients
- 16 ounce package premade chocolate chip cookie dough
- 16 Oreo cookies
- 18 ounce box brownie mix plus ingredients called for on box
Instructions
- Preheat oven to 350 degrees F and line a 9×9 or 8×8 pan with parchment paper.
- Gently press the cookie dough with your hands into the bottom of the dish so it completely covers.
- Arrange the oreos evenly across the cookie dough.
- Prepare the brownies according to the back of the box, and pour evenly across the oreo layer.
- Bake for 35-40 minutes or until fully baked.
- Allow to cool completely before slicing and serving.
Jenn’s Notes
- To Store: Store your Slutty Brownies in an airtight container on the countertop for up to 3 days or in the refrigerator for up to 5 days.
- To Freeze: These brownies can also be frozen for up to 3 months. I recommend cutting them into squares and placing in a freezer bag or freezer-safe container. Defrost on the countertop when you are ready to serve.
- Make sure you let your brownies cool completely before slicing them–it will improve the texture and taste of the brownie. Brownies are still cooking when you pull them out of the oven. They need this cooling time to finish baking and firm up.
- Be sure to line your pan with parchment paper. Not only will this prevent your brownies from sticking, it also creates a nice little carrier that allows you to easily remove your brownies in one solid slab, especially because this recipe has 3 heavy layers.
Can you use golden oreos instead of the chocolate ones?
You sure can! Great variation!
i made these brownies in a 9×13 pan lined with parchment paper, sugar cookie mix, 24 oreo cookies and then I layed a andes candy mint on each cookie before putting brownie mix on top then baked as usual
Love these and they’re super tasty! It took my brownies a LONG time to cook the first time around, so the second batch I lowered to 325° for an hour and they came out perfectly!
Amazing! I’ve made over 5 times and ppl devour it
