It’s all about Slutty Brownies today! Layers of cookie dough, Oreo’s and homemade brownie batter = it’s perfection. Keep reading for all the tips and tricks 🙂
A few weeks ago I was perusing the interwebs, mainly pinterest, because it’s my latest obsession and I spend an inordinate amount of time pinning things that I want to eat, and things that I want at my wedding. I’m not quite sure how people planned weddings before Pinterest. It’s kinda the greatest invention of all times. But while I was knee deep in my wedding pinning extravaganza, I stumbled across something called Slutty Brownies.

Clearly these caught my attention immediately. They are the brilliant creation of The Londoner and they are basically it’s a SUPER POWERED brownie made with layers of cookie dough, oreo cookies, and then a rich and decadent brownie layer. They are EVERYTHING. Seeing as how I’m a private chef, I made them for every single person in my life, including Jessica Simpson who is my current private chef client, and when asked on Leno what made them slutty she replied.. it’s because a lot of things go into them. GENIUS.
They are decadent. One small bite will be enough to satisfy any sweet tooth but why stop there!

You could easily make these with box mix, which is what the original recipe I found calls for, but I took it one step further and made these with my all time favorite rich chocolate-y brownie recipe and my favorite chocolate chip cookie dough recipe. The Oreo in the middle may seem slightly out of place because you might think it’s going to be this crunchy layer between two super soft and chewy layers, but let me reassure you that it’s not. The Oreo kind of soaks up a bit of moisture from the brownie batter and cookie dough and just adds that extra bit of fabulousness.

Make Slutty Brownies immediately.
They’ll change your life. The first 2 times I made these, I cut them right away to serve them and they kinda fell apart a bit since they were still crazy warm, and that’s totally one way to go. If you’re serving them fresh out of the oven, add a scoop of vanilla ice cream just for another layer of decadence and serve away. If you’re going to let them sit for a few hours, you’ll get a super gorgeous cut square and can grab it and go. Either way, they are awesome.
VERY IMPORTANT SLUTTY BROWNIE FAQ’s:
- This is the pan I bake these in – it’s a 9×9 square pan from Amazon and it’s the best. It’s a non-stick square pan – which is what you need. A glass pan or a pan of another size won’t yield the same results as the photos here.
- Cool the brownies once they come out of the oven for at least 1 hour before slicing and serving if you want perfect square pieces.
- You can use any kind of Oreos you want – double stuffed, regular, flavored, birthday cake, red velvet etc
- IF you use a box mix for the brownie layer, you won’t want to use the entire batter as it yields more than my homemade brownie recipe. You just want to have enough brownie recipe to cover the oreos on the top layer.

Slutty Brownies
Ingredients
For the Brownie layer:
- 10 tablespoon unsalted butter
- 1 1/4 cups white sugar
- 3/4 cup cocoa powder
- 1/2 teaspoon kosher salt
- 2 teaspoons vanilla extract
- 2 large eggs
- 1/2 cup flour
For the Oreo layer:
- 1 package of Oreo regular stuffed or double stuffed
For the Cookie Dough layer:
- 1/2 cup unsalted butter at room temp
- 1/4 cup brown sugar
- 3/4 cup white sugar
- 1 egg
- 1 1/4 teaspoons vanilla extract
- 1 1/4 cups flour
- 1/2 teaspoon salt
- 1/2 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1 cup semi-sweet chocolate chips
Instructions
For the Brownie layer:
- In a medium saucepan, melt the butter over medium high heat. Add the sugar and cocoa powder once the butter is melted. Whisk to combine and remove from heat. Add the salt, vanilla and eggs and continuously whisk until the eggs are combined. Add the flour and continue to mix. Set batter aside.
For the Cookie Dough layer:
- Cream together the butter and sugars in a mixer. Add the egg and vanilla, making sure to scrape down the sides of the mixing bowl. Add the flour, salt, baking soda and baking powder and mix on low until everything is incorporated. Fold in the chocolate chips. Set dough aside.
Assembly:
- Preheat the oven to 350 degrees F and line the bottom of a 9x9 baking pan with tin foil or parchment paper and then spray the foil/paper with a spritz of non-stick baking spray.
- Layer the cookie dough on the bottom of a 9x9 baking pan, pressing down to form the bottom of the slutty brownies. Layer as many oreos that will fit on top of the cookie dough. No need to overlap. One single layer will do.
- Pour the brownie batter on top of the oreo layer and make sure it's evenly layers on top.
- Bake for 35-40 minutes. Test with a knife to see if the center is done. If the knife comes out clean, let the brownies rest for at least 2 hours before serving. If the knife comes out with batter still on it, allow the brownies to bake about 5 minutes more. Slice and serve.



oh dear Lord, these are insane!
Oh my. These brownies look AMAZING!
They are gooooood~!!!!!
I have made these myself before and I agree, they are PERFECT to eat while indulging in some trashy tv like Real Housewives 🙂
Ha! Love the title!! These sound so freaking yummy!! Dangerous though…so, so, dangerous.
Holy wow, these look freaking delicious!! I love the combination of sinful ingredients in this that makes a slutty brownie haha..these are so dangerous, I’m sure I’d eat at least 3 or 4..
I can’t think of enough adjectives to describe how these look! I would like to try one immediately!
The only thing more dangerous right now than Pinterest, is this recipe! Like you, I’ve been spending way too much time pinning things to my virtual pin boards. These brownies…oh. w.o.w.
I think I just found my perfect postpartum brownies. Bookmarked!
These brownies look very naughty to me 🙂
I’ve booked marked this page, thanks so much for sharing this recipe!
You had me at the name! These look awesome! It’s like a brownie with all my faves slapped packed into one 🙂
Love the slutty brownies!! Gotta check out the Londoner…
Omg, I bet these caught many people’s attention! lol. Great recipe for the kids! I too spend many hours on pinterest! have a great day!
Whoa. These are ultra slutty. Count me in!
I bet grasshopper cookies would be a good middle layer too.
They are great with Peanut butter cups, or Double stuff Oreo.!!! and the cookies that have the marshmallows on the top of them !!
Everything I could ask for in a brownie! Wow, I will have to try these
Oh my goodness, these things are crazy! And their name is pretty hilarious, by the way.
Yes, a very naughty brownie indeed! It looks darn delicious!!
These looks ridiculous. These totally should come with a warning like “will cause tightening of jeans”. I am druelling just thinking about these
These are so freakin’ awesome. I need to stay far, far away from them…
Cookie dough? With brownies? I’m in heaven.
Definitely a very naughty brownie!
Oh, my word! Slutty indeed and positively divine 🙂
they look amazingly delicious, I know when I make them I want to make them again and again….maybe 23 times 🙂 too
Slutty indeed – feel very sick just looking at the recipe for this over the top sweet creation – there’s a dessert at Cecconi’s which has caramel and chocolate that the kids call the Delicious Yummy – one bite is all you need and even Remy can’t have more than two or three – this kinda reminds me of that!
OK. Stupid question, for the browning mixture. Your refer to the sugar as ‘white sugar’ so you mean regular granulated sugar? Or “confectioners” sugar which is white?? Just want to clarify…so this can be made correctly. Thank you. :o)
white sugar!!
These look like the most perfect dessert all in one bite!
As I looked at this recipe the Other Half came up and looked over my shoulder and asked me when I was making this – so awesome, this will get added to my “make-soon-to-keep-him-happy” list 🙂
I went into a coma just reading this recipe. OMG. Can’t wait to try these.
Dang, it’s like they’re not even *trying* to hold it all in. What is the world coming to? 😉
No, really, I’m just bitter because I’m gluten free and can’t make these. At least not without some extra work.
No extra work. I’ve made these with gluten-free flour and Kutos cookies and they were AWESOME!!!!
Do you happen to have the GF recipe? Would love copy if you did have one.
Hi Nicole! Unfortunately I don’t. Sorry!!
I saw this this morning and made them today…had to make them today! They are sooooo good, thank you. One thing? I am at 5000 feet so baking is always a bit of guesswork. I usually add some flour and things work fine but this time I tried it as written. They were perfect! But…they took much longer to bake? At 30 minutes the knife was till gooey so I added 7 min. Still gooey so I added 7 more. Still gooey so I added 5 more. Now the tops are nice and firm and the insides still tender and moist? 19 minutes longer?
The same thing happened to mine. I kept adding 5 more minutes each time because the knife kept coming out gooey, so it was more like a total of 50 minutes. I didn’t get to try one though to know how they were since I sent them back to school with my son.
I’m so glad i read this. Mine have currently been in the oven for about 40mins and still totally goey. Was starting to think I’de never taste.
Already shuffling my schedule around in my head in attempt to find time to make these asap…. thank you!
These look like pure evil!
looks awesome but what is AP flour??????
All Purpose Flour! Just the normal kind from the grocery store 🙂
All-Purpose Flour
*THUMP*
That was me passing out from the thought of this sinful dessert. These are all kinds of wrong girl!!!
I have been WAITING with bated breath for this post to go up. Oh thank you for bringing these (fabulously named treats) into my life.
omg! love them 🙂 Thanks Tara!
Wowza. I need these in my life, immediately. If only I’d known about them when I went through the worst break-up of my life this past summer…although maybe it’s a good thing that I didn’t…I surely would have eaten the entire pan! Can’t wait to make these!
That looks delicious! I want to try a version using only the cookies from the oreo with my own buttercream frosting. Have you tried something like that?
never tried that – but it sounds delish!!!!
Have you ever made it into a 9×13? Do you double it?
I would double it for a 9×13 for sure 🙂
Soooo amazing 🙂
I needed an ooey-gooey dessert to make for the fellas who have been helping me out at work. This is definitely it!! They look incredible. Double batch you say? I think so! 😉
THE best brownies in the entire world!!! PS I think the link back to me goes to The Londoner. PPS I want one of these tomorrow. I actually dream about these. I ate at least half the pan.
aaaaaaahhhh i fixed the link 🙂 My bad!! I’ll totally make these again this week!
How did I miss these!!!!??? They look delicious, but the name may be the very best part!
Those look crazy good! Pinned!
slutty brownies – i love it!
I think I just died and went to heaven. Sinful. Decadent. Perfect. 🙂
In the interest of saving time because I have to make salted caramel brownies and cookies tonight too, I was wondering if I could use a brownie mix instead of making the brownie batter from scratch. Think it would work the same?
Hi Jamie! For sure a brownie mix would be perfect! Thanks 🙂
I saw these on your instagram feed and have to say, WOW!!!!
These brownies look too good to be true! I’m impressed with the beauty of this dessert!
What a great idea for a long snowy weekend with no where to go! Kind of like this weekend!!!
