Why I Love This Recipe
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, cheeky name..YES. Slightly different than the famous Knock You Naked Brownies I posted about last month.
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.
What is a Slutty Brownie?
Clearly these caught my attention immediately. Slutty Brownies 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.
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.
Substitutions and Variations
Like I said above the original recipe calls for box brownies. My recipe uses homemade brownies. If you are in a time crunch or want to simply the recipe by all means use box brownies.
If you really want to simplify you could also use premade cookie dough, something along the lines of toll house etc.
For holidays I like to swap out plain Oreos with the seasonal Oreos. Example: Orange ones for Halloween, Red and Green ones for Christmas, etc.
I have also been known to make Slutty Blondie Brownies and Smores Slutty Brownies

Ingredients
For the Brownie Layer:
- 10 tablespoon unsalted butter
- 1 ¼ cups white sugar
- ¾ cup cocoa powder
- ½ teaspoon kosher salt
- 2 teaspoons vanilla extract
- 2 large eggs
- ½ cup flour
For the Oreo Layer:
- 1 package of Oreo regular stuffed or double stuffed
For the Cookie Layer:
- ½ cup unsalted butter at room temp
- ¼ cup brown sugar
- ¾ cup white sugar
- 1 egg
- 1 ¼ teaspoons vanilla extract
- 1 ¼ cups flour
- ½ teaspoon salt
- ½ teaspoon baking soda
- ½ teaspoon baking powder
- 1 cup semi-sweet chocolate chips
How to Make Slutty Brownies
Step 1: 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.
Step 2: Add the flour and continue to mix. Set batter aside.
Step 3: 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.
Step 4: 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.
Step 5: 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.
Step 6: Pour the brownie batter on top of the oreo layer and make sure it's evenly layers on top.
Step 7: 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.
Storage
The easiest way to store these treats is to leave them in the baking pan and cover with some tin foil and refrigerate.
However you can also take them out the pan and put them in your favorite glass ware storage containers and refrigerate or freeze.
Tips and Tricks
- This is the pan I bake these in - it's a 9x9 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 slutty 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.

Nutrition Information
do I really need to make the brownie batter via sauce pan or can I just mix it normally? 🙂
you just need to melt the butter - so if you melt it in the microwave, you can mix it all normally if you want!
thank you so much 🙂
These didn't turn out right at all! Which is terrible, because they're absolutely great in theory. I had to leave it in the oven for about an hour before the brownie layer was done. It was quite a mess, really. I'm wondering what I did wrong, because everyone seems to be raving about these.
P.S. I followed the recipe to the T.
Hi Gauri!
One quick question - what size pan did you use?
I used a 9x9 pan 🙁
But I'm going to keep trying these until I get them right, because look how beautiful!
9x9 is the perfect size!
Next time you give them a go - take them out of the oven at the given time, and let them cool. The brownies continue to bake a bit once they are out of the oven due to the residual heat... and then refrigerate them once they have cooled to room temp to firm everything up! Keep me posted for sure 🙂
Hi Gaby....I made these tonight. They are awesome! I didn't have alot of Oreos, but they were still great!!!! Check them out on Instagram.... @dulceminamd...
yummmmm love it!!
These are AMAZING! It is so worth using these recipes instead of the store bought. I would recommend refrigerating them over night before cutting into them. That way they hold together and still taste fudgy delicious.
yayyyy!! so glad you loved them Amelia!! 🙂 Thank you!
I made these for dessert this weekend - big hit! This is a keeper! Of course with a bunch of kids - and their friends over - we'll have to change the name of these brownies! LOL!
In my house( we have my two little sisters that are 8 & 6) we call them Sloppy Brownies
I added carmel pieces ntop of the oreos and used a Marie Calender brownie mix and Nestle toll house resipe for Chocolate chip cookes. Totally delish and called for milk and lots of it!
omg yummmmmm
Hi Gaby,
I tried to make these for a party using cookie and brownie mix just as a time saver and the brownie layer just would not cook. I used a square glass pan. I kept putting them back in the oven for at least another 20-30 minutes in intervals of 5-10 minutes and yet the middle of the brownie layer was still runny and undercooked. Do you have any idea why this happened? I can't seem to figure it out!
Hey Taylor! I've used box brownie mix too when I'm in a pinch for time. And I mut say, the glass pan will make a bit of a difference in baking time but it shouldn't be 30 minutes worth. Do you have another pan you can try - or a bigger glass pan, and then the brownies would be a bit thinner? Let me know! I'm happy to work through it with you until they are perfect!!
It's amazing!! I loved the recipe, its delicious! But 30-35 min in the oven is to much..
Hi Isabelle! How long did you bake it for - and did you use a different size pan? I'd love your feedback 🙂 Thanks!
I wanted to know if I could use a brownie bites pan. If so, at which temperature should I bake them and for how long?
You can totally use a brownie bite pan! Same temperature for sure - but I've never done it in that kind of pan so I don't know about the length of time. I'd just start with about 15 minutes and keep my eyes on it 🙂
Hey does it matter if you use salted butter for both the brownie and cookie recipe?
Hey Taylor! I always use unsalted butter - but to be honest, if you only have salted butter just go ahead and use that and omit the extra salt from the recipes 🙂
My best friend's mom and I have both made these and we have both had the same huge issue...the oreos take all the moisture from the brownies and cookie dough and you're left with this hard dessert that the brownie completely falls apart on...not sure how to fix this or how everyone else is gettin such epic results but does anyone have any ideas on how to make the oreos not dry everything else out so much?
Hey Amanda! Are you using the homemade cookie and brownie recipe? I just did a step by step recipe for this on the peppermint slutty brownie post - you can take a look and see if I addressed your question there.
Let me know! Feel free to email me directly and I'll help out at much as possible!!! Whatsgabycooking@gmail.com
Hey do you think it would be ok if i made the batters in the morning and then combined and cooked them at night?
Yes! Absolutely!!
I made these both ways, from scratch and with the boxed mixes. SOOOOOO Good either way. I went a little crazy with my 4th batch for a cookie party: added Rolos, and marshmallows to the Oreo layer then topped with the brownie mix. They were super decadent and a big hit with the other partygoers.
yay!! they are the best! 🙂 I love the rolo addition!
Today is my birthday and I made these for myself for the first time and oh goodness they came out so perfect. I added swirls of whipped cream to each brownie when serving. Not only were they beautiful they were heavenly to eat 😀
I started making these and my brownie mix is a little lumpy and not as smooth and glossy as it usually is. Is it supposed to be that way?
