What Are Slutty Brownies?
At their core, slutty brownies are a triple-layer dessert bar made from cookie dough, Oreo cookies, and brownie batter stacked, baked, and totally irresistible. The name may be cheeky, but the treat itself is serious business: a cookie Oreo brownie mashup so indulgent it almost feels illegal.
The concept went viral thanks to food bloggers and Pinterest boards, earning cult status for its ridiculous (in the best way) combo. Each layer plays a role: the cookie dough offers chew and sweetness, the Oreos bring texture and nostalgic crunch, and the brownie layer ties it all together with rich, fudgy depth. It’s a cookie Oreo brownie dessert that hits all your sweet spots at once.
This isn’t just a brownie with stuff in it. It’s a stacked experience one that’s been remixed a hundred ways (blondie base, red velvet Oreos, peppermint twists), but always with the same decadent heart.
What Makes Them “Slutty,” Anyway?
The nickname started as internet humor the idea being, “a lot goes into them.” And honestly? Fair. This dessert layers it all without shame, creating a no-boundaries bar that tastes as wild as it looks.
FAQ – Are Slutty Brownies Always Made with Oreos?
Yes, Oreos are the classic middle layer but you can swap in other sandwich cookies or candies (like Reese’s Cups or Biscoff) if you’re feeling creative. Just keep the layering logic: chewy base, creamy middle, rich top.
Ingredients Breakdown (With Substitutions That Actually Work)
Let’s break down what makes a slutty brownie recipe work from the inside out — and how to swap things in when you’re low on time, patience, or pantry stock. This cookie dough Oreo and brownie stack is forgiving, but the details still matter.
The Classic Triple Threat
For the Cookie Layer:
- ½ cup unsalted butter (room temp)
- ¼ cup brown sugar + ¾ cup white sugar
- 1 egg
- 1¼ tsp vanilla extract
- 1¼ cups all-purpose flour
- ½ tsp baking soda + ½ tsp baking powder
- ½ tsp salt
- 1 cup semi-sweet chocolate chips
This gives you a chewy base that holds firm without drying out. Too lazy? Use store-bought dough like Nestlé Toll House no judgment.
For the Oreo Layer:
- 1 package classic Oreos (regular or double-stuffed)
Holiday mode? Swap in themed Oreos peppermint, red velvet, birthday cake they all work. You can even do half-and-half mixes for a fun surprise inside.
For the Brownie Layer:
- 10 tbsp unsalted butter
- 1¼ cups white sugar
- ¾ cup cocoa powder
- ½ tsp kosher salt
- 2 tsp vanilla extract
- 2 large eggs
- ½ cup all-purpose flour
Prefer shortcuts? A box mix works too just don’t use the whole batch if it’s meant for a 9×13 pan. Aim for enough batter to coat the Oreos with a thick layer, not drown them.
Ingredient Swap Ideas
- Butter → Coconut oil (for a subtle twist)
- Chocolate chips → Chunks, minis, or flavored chips
- Oreos → Peanut butter cups, Biscoff cookies, or even Thin Mints
FAQ – Can I Make These Gluten-Free or Vegan?
Yes, but choose your swaps carefully:
- Gluten-free: Use 1:1 GF flour blends for both doughs. Make sure your Oreos and baking powder are certified GF.
- Vegan: Use dairy-free butter, flax eggs, and vegan cookie dough + brownie recipes. Double-check Oreos they’re technically dairy-free but processed on shared equipment.
How to Make Slutty Brownies: Step-by-Step
This isn’t just another layered dessert. Making a proper cookie Oreo brownie requires stacking with intention and baking it just right. Let’s walk through it from base to bite.
Step 1 – Prep Your Pan (Seriously, Don’t Skip This)
Preheat your oven to 350°F (175°C). Line a 9×9″ baking pan with parchment or foil, leaving a slight overhang so you can lift the brownies out later. Grease it lightly trust me, this saves lives (and corners). You can Watch this video for step-by-step instructions Slutty Brownies.
Step 2 – Build the Cookie Base
In a mixing bowl (or stand mixer), cream your butter + sugars until fluffy. Beat in the egg + vanilla, scrape down the sides, then mix in your dry ingredients: flour, baking soda, baking powder, salt. Stir in those chocolate chips last.
Press this dough into your pan evenly. Use a spatula or clean hands. It should feel like a soft mattress you want to dive into.
Step 3 – Oreo Layer Time
Place your Oreos directly on top of the cookie dough in a single layer. Don’t press down too hard. Just nestle them in.
You can break a few in half to cover the corners if needed but no overlapping.
Step 4 – Brownie Blanket
In a saucepan over medium heat, melt the butter, then whisk in sugar + cocoa powder. Take it off the heat and let it cool for a minute (important!). Whisk in eggs + vanilla, then fold in the flour. Find out how to choose the best cocoa powder for baking
Pour this brownie batter over the Oreo layer, smoothing it to the edges. You want full coverage without overflow.
Step 5 – Bake It Like You Mean It
Bake for 35–40 minutes, or until a toothpick poked through the brownie layer comes out with just a few moist crumbs. If it’s gooey like batter, give it 5 more minutes and test again.
Cool completely in the pan at least an hour. For clean squares? Two hours minimum.
FAQ – Why Did My Center Stay Gooey?
Slutty brownies are thick, so baking time varies. If your middle is underdone but edges are perfect, cover with foil and bake 5–10 more minutes. Also: make sure you’re using the right pan size (9×9″) and not a glass dish, which bakes slower
Pro Tips for Perfect Results (Texture, Timing & Tools)
Slutty brownies might look wild, but baking them well takes finesse. Here’s how to avoid the common pitfalls and upgrade your cookie Oreo brownie dessert from “good” to legendary.
Don’t Wing the Pan
Use a 9×9″ metal square pan, non-stick if possible. Glass or ceramic pans hold heat differently and often underbake the center while crisping the edges. A metal pan gives you even heat and consistent results.
Bonus: line it with parchment and let the edges hang over so you can lift out the whole slab once cooled.
Mind the Bake Window
These brownies are thick, and each oven is a little different. The goal is that sweet spot where the brownie top is set, the Oreo middle is soft (not soggy), and the cookie base is just golden.
- Start checking at 35 minutes with a toothpick in the center.
- You want moist crumbs, not wet batter.
- Edges should look matte and slightly pulled from the sides.
Chill Before You Slice
Want clean-cut squares? Let the whole pan cool for at least 1–2 hours. Still warm? Great with a spoon. But if you’re going for party-ready presentation, patience pays off.
Want the ultimate clean cut? Chill them in the fridge for 30 minutes before slicing with a hot knife.
Flavor Twists That Work
- Swap Oreos for Reese’s Cups or thin mints
- Use white chocolate chips in the cookie base
- Add espresso powder to the brownie batter for richness
- Mix crushed pretzels into the cookie dough for a salty crunch
FAQ – Can I Double This Recipe for a Crowd?
Yes double everything and use a 9×13″ pan. You may need to extend the bake time to 45–50 minutes. Still test the center with a toothpick and cover with foil if the top darkens too quickly.
Storage and Make-Ahead Guide
Slutty brownies are like good drama: best when they’ve had time to cool off. Here’s how to keep them tasting as good on day three as they did fresh from the oven.
Room Temp or Fridge?
- Short-term (1–2 days): Store in an airtight container at room temperature. They’ll stay soft and chewy.
- Longer storage (up to a week): Refrigerate in layers with parchment between them. This actually makes them fudgier like a chilled brownie bar.
Freezing for Future Cravings
Slutty brownies freeze beautifully. Let them cool completely, cut into squares, and layer them in a freezer-safe container with parchment. They’ll last up to 2 months.
To thaw: leave on the counter for 30–60 minutes or microwave for 10–15 seconds.
Make-Ahead Tips
- You can make and layer the raw bars, then cover tightly and refrigerate overnight. Bake fresh the next day.
- Or, fully bake them, cool, cut, and store for the week. They hold up for bake sales, road trips, or “just one more bite” moments.
FAQ – How Long Do Slutty Brownies Stay Good?
At room temp: 2 days.
In the fridge: 5–7 days.

Frequently Asked Questions (Slutty Brownies FAQ)
How do you make a quick and easy brownie?
Use a box mix seriously, it’s the easiest shortcut. Combine with water, oil, and eggs, then bake. For extra richness, add chocolate chips or a splash of espresso. Want single-serve? Microwave mug brownies are your friend.
What are the 5 ingredients in basic brownies?
At its simplest: butter, sugar, eggs, cocoa powder, and flour. That’s the bare bones of a fudgy brownie. Everything else salt, vanilla, chocolate chunks just adds depth.
What ingredient makes brownies more moist?
Fat is your best friend here. Butter or oil keeps brownies moist. Using more brown sugar than white can also add chewiness. And slightly underbaking? That helps lock in that gooey magic.
Can you eat 10-day-old brownies?
If they’ve been stored in the fridge or freezer, yes especially if they still smell and look fine. At room temp? Probably not. They’ll be dry or possibly stale after 4–5 days. Use your senses (and common sense).
What makes brownies fudgy vs. cakey?
It’s all in the fat-to-flour ratio. More fat (butter, chocolate) = fudgy. More flour and leavening (like baking powder) = cakey. Also, how long you beat the eggs can impact texture more air = fluffier brownies.
Are brownies healthy?
Let’s be real not really. Slutty brownies are peak indulgence. But you can tweak recipes: swap some sugar for maple syrup, use whole wheat flour, or toss in shredded zucchini. Just know: the more “healthy” it gets, the more it may drift from what your brain really wants gooey chocolate joy.
Can you make brownies without eggs?
Yes. Try flax eggs, applesauce, or yogurt as substitutes. They’ll slightly change texture (denser or softer), but still bake up beautifully. This works great if you’re vegan or out of eggs mid-craving.
Worth Every Bite (And Every Calorie)
Slutty brownies aren’t just a dessert they’re a moment. A sweet, layered, slightly over-the-top moment that doesn’t apologize for going all in.
