Introduction: The Story Behind the Slutty Brownie
If you’ve never heard of Slutty Brownies, prepare yourself for an indulgent ride. These gooey, decadent treats are the result of a genius combination of Oreo cookies, cookie dough, and fudgy brownies. It’s as if someone took all your favorite desserts and stacked them on top of each other in the most sinfully delicious way possible.
This recipe holds a special place in my heart (and my kitchen), not just because of how delicious it is, but because it’s the kind of dessert that brings people together. I remember the first time I made them; it was a rainy afternoon, and I was craving something sweet that would melt away the stress of the day. I took my usual brownie recipe and decided to get a little “slutty” with it – adding layers of chewy cookie dough and rich Oreo cookies in between. The result? An irresistible dessert that has become a go-to in my baking repertoire.
Let’s dive in and get to the good stuff. Slutty Brownies are all about layers of pure joy. Imagine biting into a crunchy Oreo, only to be met with a soft, gooey center of brownie and cookie dough. Trust me, this dessert isn’t for the faint of heart – but it’s definitely for those who enjoy a little indulgence.
Ingredients
For the Cookie Dough Layer:
- 1 ½ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 cup unsalted butter, softened
- ¾ cup granulated sugar
- ¾ cup brown sugar
- 2 large eggs
- 1 tablespoon vanilla extract
- 2 cups chocolate chips (semi-sweet or milk, your choice)
For the Brownie Layer:
- 1 box brownie mix (preferably a rich, fudgy variety)
- ½ cup vegetable oil (or the oil specified on your brownie mix box)
- ¼ cup water
- 2 large eggs
For the Oreo Layer:
- 12 Oreo cookies (more if you like your brownies extra “slutty”)

Instructions
Step 1: Prepare the Cookie Dough
In a large mixing bowl, whisk together the flour, baking soda, and salt. Set it aside for later.
In another bowl, beat the butter, granulated sugar, and brown sugar together until the mixture is light and fluffy (about 2-3 minutes). I use a hand mixer, but a stand mixer works just as well.
Next, add the eggs and vanilla extract. Beat until fully combined, scraping down the sides of the bowl as needed.
Gradually add the dry ingredients (flour mixture) to the wet ingredients, mixing until just combined. This is where the magic happens. The cookie dough should be thick and soft, ready to spread into the pan.
Fold in the chocolate chips, making sure they’re evenly distributed throughout the dough. Set the cookie dough aside.
Step 2: Prepare the Brownie Batter
Now, let’s get to the brownie layer. In a separate bowl, prepare the brownie mix according to the package instructions. Most boxes will call for vegetable oil, water, and eggs, but make sure to check your specific brand’s instructions for accurate measurements.
Once mixed, set aside.

Step 3: Assemble the Layers
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or lightly grease it with butter.
Start by spreading an even layer of cookie dough in the bottom of the prepared pan. Use your hands or a spatula to press it down into an even layer. Don’t worry if it’s a little thick – it will bake beautifully!
Next, place the Oreos on top of the cookie dough. You can line them up in rows or go wild and make it a fun, haphazard arrangement. Either way, the more Oreos, the better.
Pour the brownie batter over the Oreo cookies, spreading it evenly with a spatula. Don’t worry about the Oreo layer sinking – that’s part of the fun!
Step 4: Bake and Watch the Magic Happen
Pop the pan into the oven and bake for 30-35 minutes, or until the top is set and a toothpick inserted into the center comes out with only a few moist crumbs (not raw batter).
While your Slutty Brownies are baking, the house will start to smell like heaven. The aroma of baking cookies and brownies will mingle in the air, and you’ll be counting down the minutes until you can devour your creation.
Step 5: Let Them Cool (If You Can Wait)
Once your brownies are done baking, remove them from the oven and let them cool for about 10-15 minutes. It’s hard, but trust me – this step is crucial for getting those beautiful layers to set properly.
Once they’re slightly cooled, cut into squares. The edges will be slightly crispy, but the center will remain wonderfully gooey.

Tips for the Perfect Slutty Brownies
- Layer with Love: The key to these brownies is making sure each layer is evenly spread. This ensures you get the perfect balance of cookie dough, Oreo, and brownie in every bite.
- Don’t Overbake: Slutty Brownies should remain fudgy in the center. Overbaking them can result in a dry texture. Keep an eye on them, and remember that they will continue to cook as they cool.
- Extra Oreo Fun: For an extra indulgent treat, you can add more Oreos in the middle or top of the brownies before baking. You can even crumble up a few and sprinkle them on top for added crunch.
- Freeze Them for Later: These brownies freeze beautifully. If you have leftovers (though, let’s be honest, that’s unlikely), wrap them in plastic wrap and store them in the freezer for up to a month. When you’re ready, let them thaw for a few minutes before devouring.
- Serve with Ice Cream: Want to take these brownies to the next level? Serve them warm with a scoop of vanilla ice cream or whipped cream. Trust me, it’s a dessert experience you won’t forget.
Why Slutty Brownies Are the Ultimate Indulgence
Slutty Brownies aren’t just a treat – they’re an experience. The moment you take your first bite, you’re hit with the soft, chewy cookie dough, the crunch of the Oreo, and the rich, fudgy brownie layer. Each bite offers a different texture, yet it all melds together into a perfect dessert symphony.
These brownies are not for the faint of heart. They are unapologetically indulgent and delicious. But let’s be real – sometimes, you just need to treat yourself to something extra. And these brownies are the perfect way to do that.
