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
I haven't tried the recipe yet, but I want to show my classmates to try this. Our teacher made us look out for good blogs and I think I found one of the best in our class and possible the internet. I just hope my cooking teacher uses some of your recipes. Especially the slutty brownies.
My pan is 8.5x8.5 and almost 2 high (it's Australian) will that be ok?
yes!
Thank you! Will be making this on Thursday!
Just had these at a party and they were so good. They were also made the quicker way with the ready made -cookie dough, mini oreos, and brownie mix. Thanks!
They're cooling now. I did a 1.5X recipe and baked in a 9X13 pan. You're right, the baking time gets a little crazy but they look like they came out okay. We'll see when I cut them in a couple hours.
I also added some unsweetened baking chocolate to the melted butter in the brownies. I find it helps create a more dense and fudgy brownie.
Thanks for the recipe! I'm excited about checking out more recipes your page!
Love, love, love these. Quick, easy and delicious!
I've been making these for years. I use refrigerator dough in tubes and lightly press down, use mini Oreos so you get lots in a square and add a brownie or a blonde mix like this recipe. We do this for bake sales and it cuts the time to make many batches with the premade chocolate chip dough. Always a winner!
Love the idea of these and just about to bake them. However i'm from the Uk and the conversions appear to be very difficult as lots of websites tell you different measurements! Any chance you could reccomend a website or place to find correct conversions as i'm hoping these brownies turn out incredible! xx
I'm from the UK and have made these a few times now. Measuring cups are readily available over here and make things so easy. The only thing I have an issue with is cups and sticks of butter. Most older cookbooks have oven temperature converters. Have you tried Google? They have all sorts of converters. I've even made slutty blondies using custard creams when I couldn't get golden Oreos. Good luck, you will enjoy these.
Do these freeze well? I'd like to make them ahead of time for an event in a week from now.
Lindy
YES!! they freeze beautifully
Made these for the 4th of July cookout. I would feel weird saying they were called "Slutty Brownies" to my parents so I just called them "Gaby's Brownies" instead. We loved them.
Why is it that glass baking dishes dont work?
it just changes the baking time!! metal works best!
Shit I used 3 eggs instead of 2 for the brownie batter. How will it turn out. I just put them in the oven. Feeling like such a fail. I had one fail yesterday with some cream cheese cake. Can't ruin again today
how did it go?
I don't have a 9x9 square pan, but have a 9" circle cake pan. Would you advise to use that or maybe a square tin foil cake pan?
either would work!
Hey Gaby- so excited to make this recipe tomorrow for a friend's birthday; however, I only have an 8x8 square metal pan. Is this okay to use? I assume I just use a little less brownie batter on top and bake a bit longer.
Thanks!
P.S. I just got back from a two week trip to Italy and we used your Rome and Florence guides ALL. THE. TIME. Your restaurant recommendations ranked as our favorite meals from the trip. Thank you!!! Also now addicted to the Aperol Spritz.
omg LOVE hearing that! I want to go back to Italy tomorrow! And yes an 8x8 would work! You can use the same measurements, you'll just need to bake it a touch longer since it will be thicker than normal!!
Hi, great instructions is there a link where I can see you make them ?! Thanks !
Hi.
So these look amazing and I can't wait to try them. But I have go wonder: are they slutty brownies for th reason Jessica Simpson said or because they're indulgent and unapologetic? It seems like the first reason isn't as good as the others.
Thanks
