Slutty Brownies are an easy layered decadent indulgence with a soft and chewy chocolate chip cookie base, an Oreo cookie center, and a fudgy brownie topping. This recipe is so simple and quick because it’s made with your favorite boxed brownie mix, packaged cookies, and pre-made dough that forms a triple-decker dessert in 5 minutes–when baked, these are the BEST bars!
Simple Slutty Brownie (with shortcut!)
Don’t let the racy name, “Slutty Brownies,” fool you–these cookies are not x-rated and certainly cannot be “considered in bad taste” as it implies–because these bars are the most brilliant creation of delicious decadence!
While this recipe may not be the most original or have any twists and variations (why change what is already perfect), it is definitely the easiest way to bake Slutty Brownies because it uses shortcuts: a box of brownie mix and pre-made cookie dough not only makes it simple but also leaves you with one bowl to clean and minimal measuring.
I love the variety of textures in this triple-layered sweet treat. A chewy cookie, fudgy brownie, and creamy Oreo center collide to make one rich, loaded brownie dessert. And while it may seem odd that the Oreos sandwiched between the two soft layers aren’t crunchy, they just kind of soak up the moisture from the brownie batter and cookie dough and make this mashup the ultimate masterpiece!

How to make Slutty Brownies
It couldn’t be any easier to make these delicious Slutty Brownies because it uses simple shortcuts. In 5 minutes, you can prepare a 3-layered decadent dessert that bakes into the best brownie bar and the most incredible sweet treat!
- Press the premade cookie dough into the bottom of a 9×9 or 8×8 pan to cover completely.
Pro-Tip: 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.
- Arrange the Oreos evenly across the cookie dough.
- Prepare the brownie batter according to the back of the box, and pour over the Oreo layer.
- Bake at 350 degrees Farenheit for 35-40 minutes or until a toothpick comes out clean when inserted.
- Cool, slice, and serve. Enjoy!
Pro-Tip: 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.
Cookie Oreo Brownie storage tips
- 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.

Slutty Brownie / Cookie Oreo Brownie Recipe FAQs
You can absolutely make your own cookie dough and brownie batter from scratch. This recipe uses premade cookie dough and a box of brownie mix because I wanted to provide a super simple, easy recipe.
Slutty brownies were first made by Kevin and Amanda back in 2011, when they weren’t even called slutty brownies (they were called Cookie Dough Oreo Brownies). The Londoner later described why they called them slutty brownies: “they’re oh so easy, and more than a little bit filthy.” Just as simple as I would’ve imagined. They are as easy to make as they are messy to eat.” And thus, the internet ended up changing the name to Slutty Brownies.
You can easily make these brownies in advance. Since these Slutty Brownies need to cool and set before you slice them, they are the perfect recipe to make the night before serving. Letting them sit overnight helps ensure they are completely set up for slicing.
The difference between cookie and brownie batter lies in their composition and texture. Cookie batter is typically softer and contains more butter and sugar, resulting in a dough that spreads during baking to create a crisp and chewy cookie. Brownie batter, on the other hand, has a higher proportion of fat and less flour, leading to a denser and fudgier texture in the final baked product.
The secrets to achieving chewy brownies include using a combination of both granulated sugar and brown sugar, as the moisture from the brown sugar contributes to the desired chewiness. Additionally, slightly underbaking the brownies and allowing them to cool completely before cutting helps retain moisture and chewiness.
