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, who is just pretty much awesome. Basically it’s a super brownie made with layers of cookie dough, oreo cookies, and then a rich and decadent brownie layer. They are totally slutty brownies. Or I guess they could easily be “I just got dumped brownies.”
So basically after I found these I made them approximately 23 times. Okay so maybe it was 12 times, but the moral of the story is that these are just downright awesome. My fabulous friend Koko and I decided that these are best eaten by oneself, with a spoon, perhaps a glass of bubbly rose and some trashy TV (I recommend the Real Housewives of Beverly Hills or Shameless). They are decadent. One small bite will be enough to satisfy any sweet tooth.
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 chocolatly 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.
So basically you’ve got to make these. They will 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.
Ingredients
- 10 tbsp unsalted butter
- 1 1/4 cups white sugar
- 3/4 cup cocoa powder
- 1/2 tsp salt
- 2 tsp vanilla extract
- 2 large eggs
- 1/2 cup AP flour
- 1 package of Oreo (regular stuffed or double stuffed)
- 1/2 cup unsalted butter (at room temp)
- 1/4 cup brown sugar
- 3/4 cup white sugar
- 1 egg
- 1 1/4 tsp vanilla extract
- 1 1/4 cups AP flour
- 1/2 tsp salt
- 1/2 tsp baking soda
- 1/2 tsp baking powder
- 1 cup semi-sweet chocolate chips
Instructions
- For the Brownie layer:
- In a medium sauce pan, 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 eggs 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:
- Pre-heat the oven to 350 degrees.
- Line the bottom of a 9x9 baking pan with tin foil and then spray the tin foil with a layer of 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 30-35 minutes. Test with a knife to see if the center is done. If the knife comes out clean, let the brownies rest before serving. If the knife comes out with batter still on it, allow the brownies to bake about 5 minutes more.
- Serve with ice cream :)

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
Step #8 is a bit confusing… How do you press down cookie dough to the tin foil when its liquidy? Won’t the oreos sink through as well as the brownie mix? Thanks
Hi Elizabeth! The cookie dough recipe here isn’t liquidy so it’s easy to push down! Here’s a little tutorial I just did: http://whatsgabycooking.com/peppermint-slutty-brownies/
Is it okay to use Ghirardelli brownie mix and my own cookie dough recipe as long as it’s not liquidy?
totally!!
The only decadent thing missing is caramel…but would that make them more than slutty? lol
I put caramel in it when I made them in between the oreos and.cookie.dough
whaaaaaat? I want some of those!! That is an extra slutty brownie
Is it necessary to add the tinfoil to the baking pan? Or is it okay to just grease the pan?
you can just grease it – but the tin foil makes it easier to pull out! Here is a step by step guide if you want

To make these brownies even sluttier, how about a bit of a glaze? I have a plan to make these to share with my co-workers (am retiring soon), and am thinking that a glaze would make them dead slutty!
So do you have to make the brownie and cookie dough mix or can you buy em
hey sage! you can totally buy them if that’s easier for you. I prefer my homemade mixes – but I’ve done it both ways and it works for sure!
my 9×9 pan is currently on loan to a friend, will these be fine to make in a 9×13? How would you suggest altering it so it would work? Thanks!
Hi Sheri! A 9×13 will still totally work. You’ll just need to keep your eyes on the brownies since they will be a bit thinner, and that will affect the baking time. Just be sure to check it every once in a while after 30 minutes to see when the center is not jiggly and almost cooked!
My brownie batter was quite thick is that normal? I followed this recipe
yup!! brownie batter should be thick
will it make a difference if I used nestle cookie dough and brownie mix? instead of doing it from scratch?
hey chelsea! yes it will make a difference because the brownie mix makes a large quantity than why my homemade recipe calls for. You can still totally do it – but you might want to use a 9×13 pan since the brownie mixture makes a lot. And it will take a little longer to bake – so you’ll have to keep checking
Well I made last night -I used a box mix for bownies cuz I was pressed for time -came out raw, everytime I chacked the brownie, -not alittle raw alot, so I had to keep adding more time by the time brownies are done the cookie dough was super hard -I gotta cut off or should I say saw off bottom layer to eat the brownie -I m gonna try this recipe again but in a 13×9 not the 9x 9 pan that’s recommend -way to thick.
hey gigi – the homemade brownie recipe for these makes a smaller quantity than if you use a box mix – so that will absolutely affect the baking time. If you use a box mix – you would be better off in a 9×13 pan because the brownies will be so thick which will take longer to bake and will make the cookie layer crispy and overbaked
Hey im just wondering how long you have to bake with 8 x 8 pan, I don’t have 9 x 9 pan…
hey becky – so they might not fit into an 8×8 pan. Do you have a 9×13?
No.. But I have 11 x 7 pan. Will that work?
This has got to be about the most delicious dessert I’ve ever seen. Oreos!! Brilliant
Hi Gaby and thanks a lot for your wonderful recipe! My grandmother as well as my mother and her boyfriend have gladly overindulged into these goodies. They’re almost gone and I only created them last night! (without the oreos
! )
I just wanted to leave something that I found useful while making them. Because I used your cookie recipe, the dough was the perfect consistency but was not packable into the container at room temperature so I put the container along with the cookie dough into the freezer and then I was able to pat it down into a nice even layer!
Thanks a lot, and I’ll be back for more of youre nice recipes!
great tip!! Thanks Alexandra!
I was just wondering if you could crush up the oreos?
