Slutty Brownies

Never mind their scandalous name, Slutty Brownies are impossible to resist. They’re made from fudgy chocolate brownies and a chewy chocolate chip cookie layer, with Oreos in the middle. There’s a reason these brownie Oreo cookie bars went viral!

Easy Slutty Brownies Recipe

Today we’re making the infamous slutty brownies. Well, my spin on the original, at least. These triple-layer brownie bars have swept the internet (for what I think are obvious reasons), and I’m mildly obsessed. I love the idea of multiple sweet treats all in one! So much so that I’ve made slutty cheesecake bars and even a slutty brookie poke cake. The Oreo-brownie-cookie combo is a hard one to resist.

Why You Should Make These Scandalous Slutty Brownies

• The best of everything. I’ve adapted this slutty brownie recipe from my fudgy cocoa powder brownies, borrowing the cookie layer from my favorite brookies, with Oreos in between. The result? Ultra-fudgy, super moist, and decadent brownies topped with the most irresistibly chewy chocolate chip cookie, filled with crunchy Oreos. A lot is going on, in the best possible way.
• Easy to make. It’s a matter of preparing the batters, layering them into a baking pan, and popping the bars into the oven. Slutty brownies take a bit of time, but the steps are super simple. Plus, these chewy, chocolatey dessert bars are more than worth it!
• Great for parties. If the name of these brownies alone isn’t a conversation starter, at least one person always asks for the recipe! With their brownie and cookie layers, irresistible chewiness, and crunchy Oreo filling, slutty brownies are guaranteed crowd-pleasers.

Ingredient Notes

I highlight some of the key ingredients you’ll need to make these triple-decker brownie bars below. Don’t forget to refer to the recipe card for a printable list with the full recipe details!

For the Cookie Layer

• Butter – I recommend baking with unsalted butter, but if you use salted butter, you can omit any added salt that comes later on.
• Sugar – Using a combination of brown and granulated sugars brings the perfect amount of moisture to the chocolate chip cookie dough.
• Egg and Vanilla – I use one whole egg plus one egg yolk to add extra richness to the cookie layer. For the best flavor, use real vanilla extract.
• Chocolate Chips – Semi-sweet chocolate chips, or any variety of chocolate chips you’d like. 
• Oreos – You’ll need about 24 Oreos, or enough to cover the full pan of brownies.

For the Brownie Layer 

• Oil – Using vegetable oil in place of butter in brownies and cakes adds tons of moisture and lightness to the crumb.
• Cocoa Powder – Unsweetened cocoa powder or Dutch process cocoa powder will both work here. Using the Dutch process cocoa will yield darker, fudgier brownies.

How to Make Slutty Brownies

While your oven preheats, grease and line a 9×13-inch baking pan and take your butter out of the fridge. After about 20 minutes, the butter should be softened enough for you to get started. Follow the steps below, and scroll to the recipe card for printable instructions.

Start With the Cookie Layer

Both the cookies and brownies involve mixing the wet and dry ingredients separately, before combining them and adding chocolate chips. Pretty straightforward. First, we’ll make the chocolate chip cookie dough:

1. Combine the wet ingredients. Cream the butter and both sugars together until they’re combined and fluffy, then beat in the eggs and vanilla.
2. Mix the dry ingredients. In a new bowl, whisk together the dry ingredients, then slowly mix the dry ingredients into the wet to form the dough.
3. Add chocolate chips. When the dough is barely combined, fold in the chocolate chips.

Make the Brownie layer

Next, we’ll mix up a quick chocolate brownie batter: 

1. Combine the wet ingredients. First, beat together the sugar, oil, milk, and vanilla. Next, add an egg.
2. Combine the dry ingredients. Next, combine the dry ingredients separately before adding them to the wet ingredients. Mix until the batter is just combined, and stir chocolate chips into this layer, too.

How to Assemble & Bake

Dough and batter? Check. Preheated oven? Check. Prepped baking dish? Check! You’re ready to assemble and bake your slutty brownies. 

A lot of slutty brownie recipes start with chocolate chip cookie dough as their base, but not these ones! We’re flipping the script on slutty brownies, layering the cookie dough on top. You’ll thank me later.

1. Brownie batter first. Add the brownie batter to the pan and spread it in an even layer. 
2. Next, Oreos. Arrange the Oreo cookies in a single layer over the brownie batter.
3. Top with cookie dough. Use your hands to press large, flat pieces of chocolate chip cookie dough over the top of the Oreo layer. I find it’s easiest to layer on the cookie dough so that you don’t miss any spots.
4. Bake. Pop your assembled slutty brownies into the oven to bake at 350ºF for 35-40 minutes. After 15 minutes, take the pan out and cover the brownies with foil to keep the top from browning. Remove the foil at around the 30-minute mark. When your brownies are done, let them cool completely before slicing.

Variation Ideas

There are so many ways that you can make this recipe your own. Here are some easy slutty brownie variation ideas to try:

• Use different Oreos. This brownie recipe will work with any type of Oreo you prefer: regular, Double Stuf, Golden Oreos, etc. Even Mint Oreos would add a fun mint chocolate brownie twist.
• Different cookie dough. Instead of chocolate chip cookie dough, you can try adding other candies like M&Ms, Sprinkles, Toffee or even chopped candy bars.
• Add frosting. Top your slutty brownies with a thick layer of Chocolate Buttercream Frosting, Marshmallow Frosting, or Oreo Frosting.

Ways to Serve

These slutty brownies are downright blissful and decadent on their own, or I’ll up the ante with a drizzle of caramel sauce. They’re also incredible when they’re warmed up and topped with a scoop of brownie batter ice cream.

Speaking of, make a brownie sundae! Serve your slutty brownies topped with your favorite ice cream, homemade whipped cream, a drizzle of hot fudge, and a cherry.

How to Store

• Counter: The baked and cooled slutty brownies can be stored airtight at room temperature. They’ll keep fresh for up to 4 days. Fridge: You can extend their shelf life by storing them in an airtight container in the fridge. They’ll last for up to 7 days.
• Can I freeze them? Yes. I recommend freezing these brownies either individually wrapped, or with parchment paper in between layers. Freeze them in an airtight container or freezer bag for up to 3 months. Thaw the brownies either in the fridge or on the counter before serving.
