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 just made these (they are baking in my oven as I type) for Christmas. I was planning on freezing them, but from the comments, it looks like it might be fine not to freeze since I'll be serving in less than three days. What do you think? Freeze or not freeze?
you can totally freeze them - I do it all the time! Just let them thaw for an hour or so before trying to cut into them!
Love this recipe! However, every time I've made these, the cookie layer oozes out from the bottom to the sides and top of the brownie layer. Am I missing or doing something wrong?
what size pan are u baking them in?
I"m using a 9x9 pan which is what I believe you specified.
yup!! that's right!! Do you let to cool all the way before slicing? Sometimes it helps to refrigerate it for an hour before you slice and serve
Yes I do! But I notice the cookie layer spilling out while it's baking. Maybe I need to make sure the foil is flush against the pan especially in the corners. That's the only thing I can think of...
I have the same issue the cookie dough comes up sides of pan nd ends up partially on top and over sides of pan. I wondered was it maybe the baking soda/powder in cookie dough mix?
what size pan are u using?
Can you make these 1 day ahead of time and then bake them?
of course!
I was planning on making a couple varieties of these brownies but after getting so frustrated with my first batch I started looking for other recipes. I would recommend refrigerating the dough before trying to press it into the pan. The cookie dough layer wasn't too bad but pressing the brownie layer over the Oreos was ridiculous! It was so sticky and hard to work with. I did end up putting the whole pan and what bit was left in the bowl in the fridge and once it was firmer it was much easier to work with. Work fast because once it warms up it sticks to everything and pulls up off the Oreos. I also used a piece of parchment paper over the top to help press it all down before I baked it. They are out of the oven now and smell wonderful.
This review was for the Slutty Blonde Brownies, the is why the brownie batter was so thick and difficult to work with.
HI Deb! You dont need to press the brownie recipe over the oreos, you should just pour it on top and then use a spoon or offset spatula to smooth it out.
feel free to watch the video for a demo if you'd like
Hi! I loved your recipe which I used to make for a work charity event. I went two steps further and made a dark chocolate ganache to go on top, followed by crushed oreos. Everyone loved it! I took a picture but it's not a perfect shot :).
Thank you for the inspiration!

Hi Gaby, can't wait to try this recipe but I'm puzzled by the AP flour. What is that? I'm.in the UK. Thanks. Olivia
its all purpose flour!! just the regular stuff 🙂
That's plain flour to us.
Gaby, would I be able to make these brownies in an 8 in circular pan?
yes, but it would change the baking time and since I haven't tested in that size pan, I can't stay exactly how long you'll need to bake them for!
Hi, I am actually cooking in a glass pan now. You indicated it doesn't cook well... can you tell me how?
When you cook in a glass pan you must reduce the oven temperature by 25 degrees and bake for the same duration of time to achieve the same result
I have made these a few times and I love them but has anyone else had problems with the cookie dough layer being undercooked?
My cookie dough seems really runny--almost the consistency of a cake batter. Is that normal for your cookie recipe? I doubled it, am doing an 11x17 pan (Have to feed a hungry college class . . . :P)
Thanks!
hmmmmmm no that's not really normal. Did you make any alterations to the recipe?
These are absolutely delicious! I made these with my 7 year old daughter today, we had so much fun! How long do they last for in a cake tin? Do I need to wrap them in plastic cling film even if they are in a cake tin? Also, do I need to store them in the fridge at all times? Thanks!
They store best in the fridge in an airtight container!! But if you wrap them up they'll last a few days on the counter too
How many eggs for the cookie dough?
1 egg - it's in the ingredient list!
I made these using chocolate fudge chocolate chip cookie dough and Thin Mints...they were phenomenal!
Is the cocoa powder sweet or unsweet?
unsweetened!
Do you have any specific store bought cookie dough and brownie mix works the best?
I've used the nestle cookie dough before and it works great. And the ghiradelli box mix - but I don't use all of it. Just enough to really cover the oreos and then I bake the remaining brownie mix into a cupcake pan
