Best Slutty Brownies
These Slutty Brownies melt in your mouth with rich layers of cookie dough, Oreo cookies and brownies. This slutty brownie recipe is easy to make whenever you want an extra-decadent treat!
Slutty brownies became a viral sensation after Jessica Simpson called them her biggest pregnancy craving on the Tonight Show. The Londoner created the name after adapting another recipe she called “a bit filthy”, and it stuck!
You can make them using store-bought cookie dough and brownie mix to save time, or follow the instructions to make the layers from scratch. They’re delicious on their own or topped with ice cream and chocolate sauce. A guaranteed hit for any party, potluck or holiday gathering!
How to Make Slutty Brownies
For this slutty brownie recipe, you’ll be putting a cookie dough layer on the bottom, an Oreo cookie layer in the middle and a brownie layer on top.
Start by lining a square 8-inch (20 cm) nonstick baking dish with parchment paper or foil. This step will prevent sticking and help you lift the brownies out of the pan after baking.
Cookie Dough Layer: You can use storebought chocolate chip cookie dough or make homemade dough from scratch. Press it evenly into the bottom of the pan to about ¼-inch thick.
Oreo Cookie Layer: Arrange Oreos side-by-side on top of the cookie dough as a single layer. Regular Oreos are fine or you can try Double Stuf or other flavors.
Brownie Layer: Make brownie batter using your favorite brownie mix or the homemade recipe below. However, you only need half of the batter for this recipe, so consider making a few extra brownies in another pan. Pour the batter evenly across the oreos – it should be just enough to cover thinly.
Bake at 350°F for 35-40 minutes. The shorter end of the time range will produce a wetter brownie while baking longer gives a cakier texture. The oreos will soften in the oven to become extra-moist so they melt in your mouth!
Make sure to always cool completely before cutting as the layers can be fragile while still warm.

Slutty Brownies
Ingredients
Cookie Dough Layer
- 16 oz refrigerated chocolate chip cookie dough, or make homemade
Brownie Layer
- 1 18-oz box brownie mix, plus ingredients called for on the box, OR the following homemade brownie recipe instead
- 1/2 cup unsalted butter, melted
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/3 cup unsweetened cocoa powder
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt
Oreo Cookie Layer
- 16 Oreo cookies, about 6-oz *
Instructions
- Preheat the oven to 350°F (177°C). Line an 8-inch square baking pan** with parchment paper and set aside.
- Press the cookie dough into the bottom of the pan using your fingertips. You want an even layer that's about 1/4-inch (1/2 cm) thick.
- Arrange the Oreo cookies in a single layer of 4x4 on top of the cookie dough. It's fine if there's some wiggle room between the Oreos.
- Make the brownie batter in a medium bowl according to the package directions (Note: you will only need HALF of the 18-oz box and ingredients called for on the box - the remaining batter can make extra brownies or cupcakes). To make homemade batter, beat the butter and sugar in a medium bowl until fluffy. Then beat in the vanilla and eggs one-by-one. Then stir in the flour, cocoa and salt until combined.
- Pour the brownie batter evenly across the Oreo cookies (it should be just enough to thinly cover the Oreos). Use a spatula to spread it out to fill the nooks and crannies as needed.
- Bake for 35-40 minutes or until a toothpick or cake tester inserted in the middle comes out clean. (A shorter duration makes a wetter brownie while a longer duration produces a cakier texture.)
- Remove from the oven and allow the brownies to cool completely in the pan for at least one hour. This is crucial to prevent the layers from deflating or collapsing.
- Use the parchment to lift the brownies out of the pan. Use a sharp knife to cut into squares. Serve with chocolate sauce or ice cream if desired.

Notes
- * Oreo flavors that work well include: Regular, Double Stuf, Chocolate Oreos, Red Velvet and even Golden Oreos. Avoid using exotic flavors like Mint or Lemon.
- ** A 9-inch square pan also works, although the Oreos don't fit in quite as nicely.

My favorite cookie dough recipe cooks for ten minutes but the box brownies are supposed to cook for longer? What should I do?
Hi Susan, Thanks for your question. The cookie dough can cook longer than 10 minutes in this recipe, since it’s kept moist by the brownie layer on top. Hope that helps! 🙂
I want to try the slutty brownie recipe. I saw it on tv with the Oreos as the first layer followed by the chocolate chip cookie dough and last the brownie mix. What size pan do I use and how long to bake this. Am anxious to try, please respond soon. Thanks. Mary Jo
Hi Mary Jo, Thanks for your question. An 8-inch square pan is the one to use for this recipe. btw, I recommend putting cookie dough as the bottom layer and oreos in the middle. Let me know how it goes 🙂
How did you cut them so perfectly? My brownies always crumble or big chunks come off with the knife. The photo shows such clean cuts – perfectly cut brownies. Look amazing! Thank you!
Hi Lisa, Thanks for your question. To get a cleaner cut, simply refrigerate the brownies for a few hours to firm up before cutting. If they’re really gooey, you might need to freeze. Hope that helps! 🙂
This is similar like my recipe , Anyway I learn something more from ur recipe. 😉
Hi Nika, Thanks for your review and glad you found something useful 🙂
How do you store these?
Hi Jenn, You can store them in a ziptop bag or airtight container to stay fresh. No need to refrigerate just like regular brownies. Enjoy!
Love, love, love this recipe. So easy and delicious.
Thank you TipBuzz. I have Rockstar status with the family.
Hi TeaBe, So happy to hear that – great for sharing, right? 🙂
Add a salted caramel layer over Oreos, sprinkle w chopped nuts. Once baked, set up in fridge, cut into small squares,then freeze. Then dip, to completely coat, into melted chocolate candy coating, I use Ghirardelli. Let set up. Awesome.
Thanks MJ and sounds amazing. That’s what these treats are all about 🙂
I am so intrigued. I will definitely try.
I also want to try a peanut butter or sugar cookie dough version with vanilla Oreos and salted caramel or blonde brownies.
wheres the video
nevermind
where did u find it
Pay special attention to the amount of cookie dough. I used too much and it was a disaster.
Does the baking time change when making a double batch in the 13×9 baking pan??
Hi Tam;
I’ve made these about a dozen times, usually in a 9×13 pan. If you make half the recipe in a smaller pan you may want to shave off 5 minutes. The real test is sticking a toothpick (or, since it’s 3 layers and rather thick, try my trick and use a spaghetti noodle instead) into the middle. What you’re looking for is a bit of crumb clinging to the stick–not wet but not completely dry. Good luck!
Good
This was the easiest tastiest dish ive made all summer?
Awesome – thanks for letting us know 🙂
