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.

I accidentally bought milk chocolate chips instead of semi sweet. Can i still use the milk chocolate for the cookie dough?
100%
My 15yo daughter made these today in lieu of a birthday cake for herself. They are so good and definitely going to become a staple in our house, thanks. I will change the name, however. Perhaps, The Best Brownies, EVER!
love it!!! happy birthday to her!
Hey, I have a question. Do the Oreos become soft or do they stay crunchy? Thanks.
they are a little soft but not mushy!!
I made these, and liked the brownie layer more than the others. Do you have the instructions to just bake those by themselves?
Make them as the recipe says (just the brownie section) and then bake in an 8inch pan at 325 for 20-25 minutes!
Thank you for the prompt reply
anytime!! 🙂
Helloo.i just made these and i followed the recipe exactly.. When i popped them in the oven the cookie layer started to overlap the brownie layer. I baked them for about 45 minutes and it seems like the top is the only thong to set.
I've taken them out and seeing if i let them cool if it'll set..i just seems too..liquid. Right now...is this normal?
what size baking pan did you use??
Sometimes when I take it out I let it set for about an hour to rest and then pop it in the fridge! - and then it's all perfect once I cut it!
I used a 9x13.
And the result after i cooled. Then was some around the outer was hard and some in the middle was really chew, almost as if it didnt bake all the way. It didn't come out as i expected, the cookielayer and the brownie layer kind of morphed. You could barely tell there was a chocolate chip layer since it sort of baked over the brownie part and overlapped. Im not sure what I did wrong?? Like i said I followed the recipe, just used a different kind of pan.
Hey Jessa - that's super weird. I haven't had that happen to me in the hundreds of times that I've made this recipe BUT I will say that the pan absolutely would change the recipe. Was it a glass pan and a different size? LMK and we can troubleshoot some more 🙂
I have made these for years in a 9x13 pan but use a family size roll of chocolate chip cookie dough, one package of Oreos and two boxes of brownie mix. Bake for 55 min at 350 and done perfectly. Just my guess but using the ingredients above for a smaller pan would cause the ingredients to as you say morph together in a larger pan. Just a thought.
Found this recipe on Pinterest. Made them last night and brought them into work today. My coworkers went nuts for them. Super easy and delish!
yay!! thanks Mattie!
I made them and they turned out perfect and delicious I was so happy I shared them with my friends at school and everyone loved them thank you. 🙂
I'm going to try to make these for the first time in my life normally I hate cooking until I saw this video and I've been dieing to make it, I'm 15 years old and I hope they taste and look delicious as yours.
Hi Gaby! Love this recipe. Do you think it's possible to mix both layers with a single oreo in between and to put them into individual cupcake tins rather than a 9x9 pan? If so, what time would you recommend to bake them?
Yes! You could layer the 3 layers in a cupcake tin - not 100% sure about timing but I'd check them after about 20 minutes and keep an eye on them after that!
Hey gaby, i dont have the cups to measure the ingredients out, how much of the ingredients do i need in grams/ml
Hey Sara! I haven't tested it in grams so I don't know perfect conversions. Sorry about that!
I'm planning on making these as Christmas gifts. Will most likely try multiplying the recipes and dividing it to save some effort. Would it better to let the mixes sit or put them in the fridge once done?
you can leave them at room temp before assembly! And it multiples great - but be sure to bake them each in a 9x9 pan otherwise the baking time gets a bit funky!
OMG I made these great treats with my nephews and they were AMAZING!! I definitely recommend these TOO GOOD!! AND WHEN THEY WERE READY I DID COME A RUNNIN
I made these just as directed. It did not change a thing. I'm now at 58 minutes in the oven. The knife keeps coming with batter on it. I have a 6 month old oven so the temp is correct 350. What happened?
Hey! Not sure what could have gone wrong? Did you end up taking them out and letting them rest before slicing and serving?
Okay, so I've made these before and love them but I made them last night, one in a 9x9 and another batch in a 9x13. I let them sit overnight like always but cut into them this morning and the 9x9 pan brownie layer is still so gooey! Like way more gooey than normal. I'm afraid to serve these, would it be foolish to try to sit back into the oven for a few minutes to try to get some of it done? I would hate to waste it.
throw 'em back in the oven for 15 and then let them rest in the fridge before cutting!!
Hi! I'm making these for the first time today and I was wondering what the purpose of the tin foil is? Did you put it over a glass pan? What if I only have a glass 9x9 pan? I might have a cake pan...idk...but how do you cut the brownies with the tinfoil?
I use the tin foil to lift out the brownies from the pan! There's a demo if you watch the video at the top of the post!
A glass pan will work - but they dont conduct heat like a metal pan so just be aware of that before starting! Here's a great breakdown - http://www.thekitchn.com/glass-vs-metal-bakeware-is-there-a-difference-food-science-217961
