What Are Slutty Brownies?

Slutty Brownies are a three-layer dessert bar made from:

1. Chocolate chip cookie dough (you can use a mix or homemade)
2. Double Stuf Oreo cookies layered in the middle
3. Boxed brownie mix, made extra rich and fudgy

They’re called “slutty” because they’re decadent, indulgent, and a little over-the-top in all the best ways. The name took off online years ago, and now people all over the world make their own version of this sinful stacked treat.

What Makes These So “Slutty”?

Let’s just say these brownies don’t hold back. They’ve got three indulgent layers—cookie dough, Oreos, and brownies—all stacked into one over-the-top bar. The name Slutty Brownies comes from the idea that they’re a little “naughty” because they mash together multiple desserts into one ridiculous treat.

The term was meant to be cheeky—not offensive—and quickly caught on as people realized there was no better way to describe a dessert that breaks all the rules in the most delicious way. There’s nothing shy about these bars. They’re messy, gooey, decadent, and fully unapologetic.

These Went Viral For a Reason

Slutty Brownies didn’t start in a cookbook—they blew up online. They first made waves around 2011 when a lifestyle blog posted the recipe and gave it the iconic name. From there, the internet exploded with love for this outrageous dessert.

The concept went viral on Pinterest, Tumblr, Reddit, and foodie forums. Why? Because:

• They looked crazy good in photos
• They were easy to make with box mixes
• And the name made people do a double take

Food bloggers, influencers, and even mainstream sites like Buzzfeed jumped on the trend, and the recipe stuck. Now over a decade later, Slutty Brownies are still one of the most searched layered desserts on Google—and for good reason.

Ingredient Breakdown

Chocolate Chip Cookie Layer:

• 1 (17.5 oz) bag of chocolate chip cookie mix – I used Pillsbury, but any brand works. You can also use refrigerated dough if you’re in a hurry.
• ¼ cup semi-sweet chocolate chips – Adds even more melty goodness.
• 1 stick (½ cup) salted butter, melted – Richens up the dough and makes mixing easy.
• 1 large egg – Helps bind everything together.

Oreo Layer:

• 1 (14.3 oz) package of Double Stuf Oreos – The extra filling matters here! Feel free to use any chocolate sandwich cookie, but Double Stuf gives that thick white stripe in the center that looks amazing when sliced.

Brownie Layer:

• 1 (18.3 oz) box of brownie mix – I used a 9×13-size box. Great Value or Ghirardelli both work great.
• 1 cup semi-sweet chocolate chips – For a little texture and bonus fudge factor.
• 2 large eggs – Creates a cakier, sturdier brownie top (better for slicing).
• ¼ cup melted salted butter – Enhances richness.
• ¼ cup milk – Replaces water to keep the batter thicker and more flavorful.

Troubleshooting Tips

• Brownies still jiggly after baking? They might just need a few more minutes. Stick a toothpick in the center—it should come out with moist crumbs but not raw batter.
• Edges overbaking? If your oven runs hot, cover with foil during the last 10–15 minutes of baking to keep things even.
• Cookie dough sticking to your hands? Lightly flour your fingers or use a wet spatula to press it evenly into the pan.
• Too sweet for your taste? Skip the extra chocolate chips or use dark chocolate instead.

Storage & Serving Tips

To Store:
Keep in an airtight container at room temperature for up to 4 days or in the fridge for up to 1 week.

To Freeze:
Slice cooled brownies into squares, wrap each piece in plastic wrap, and place in a freezer-safe container. They’ll keep for up to 3 months. Thaw in the fridge overnight or warm in the microwave for 15 seconds before serving.

To Serve:
These are incredible warm with a scoop of vanilla ice cream and a drizzle of fudge sauce. But they’re just as good straight from the fridge—gooey and firm.

Cookie Chemistry: Why These Ingredients Matter

Room Temperature Eggs = Even Texture
Cold eggs can make your batter lumpy and harder to mix. Room temp eggs blend smoother and give an even crumb.

Baking Mix Substitutions
Not all brownie or cookie mixes are created equal. Stick to family-size (9×13-inch pan) packages and check for any unique liquid ratios on the box. Adjust accordingly if your mix is thicker or thinner.

Butter Over Oil = Better Flavor
Butter gives that rich, bakery-style flavor and firmer structure. If your mix calls for oil, swapping in melted butter is always worth it.

How to Pack These for Gifting

Slutty Brownies make awesome edible gifts—just be sure to cool them fully before packaging. Here’s how to keep them looking cute:

• Wrap individually in wax paper squares and stack in a bakery box.
• Use decorative tins with parchment between layers to prevent sticking.
• Add labels with heating instructions for that gooey just-baked feel.
• Skip messy toppings if you’re mailing or delivering them far.

How to Make These Without Oreos (Still Amazing!)

Want to skip the Oreos? No problem! You can:

• Use graham crackers or chocolate chip cookies instead.
• Add a layer of peanut butter or Nutella over the cookie dough for a double-layered effect.
• Just stick with cookie dough + brownie—still decadent and delicious.

They won’t technically be “slutty,” but they’ll still be indulgent and crowd-pleasing.

FAQ – Slutty Brownies

Can I use homemade cookie dough?
Absolutely! If you have a favorite chocolate chip cookie dough recipe, feel free to use it instead of the mix.

What if I only have regular Oreos?
Totally fine. Double Stuf gives more visual impact, but regular ones work just as well.

Can I make these in a smaller pan?
Yes—cut the recipe in half and use an 8×8 pan. Just reduce the baking time to about 30–35 minutes and keep a close eye on doneness.

Why are they called “Slutty Brownies”?
The name went viral online years ago—it’s playful, referring to the dessert being “naughty” because of all the indulgent layers stacked together. You can call them “Layered Cookie Brownies” or “Triple Threat Bars” if you prefer a more family-friendly version.

Can I double the recipe?
You can—but instead of a deeper pan, use two 9×13 pans to keep the layers consistent. A deep single pan might undercook in the center.
