It’s all about Slutty Brownies today! Layers of cookie dough, Oreo’s and homemade brownie batter = it’s perfection. Keep reading for all the tips and tricks 🙂
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 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.
They are decadent. One small bite will be enough to satisfy any sweet tooth but why stop there!
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.
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.
VERY IMPORTANT SLUTTY BROWNIE FAQ’s:
- This is the pan I bake these in – it’s a 9×9 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 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.
- Here’s a SLEW of savory recipes to make alongside these treats!
For the Brownie layer:
- 10 tablespoon unsalted butter
- 1 1/4 cups white sugar
- 3/4 cup cocoa powder
- 1/2 teaspoon kosher salt
- 2 teaspoons vanilla extract
- 2 large eggs
- 1/2 cup flour
For the Oreo layer:
- 1 package of Oreo regular stuffed or double stuffed
For the Cookie Dough layer:
- 1/2 cup unsalted butter at room temp
- 1/4 cup brown sugar
- 3/4 cup white sugar
- 1 egg
- 1 1/4 teaspoons vanilla extract
- 1 1/4 cups flour
- 1/2 teaspoon salt
- 1/2 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1 cup semi-sweet chocolate chips
For the Brownie layer:
- 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. 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 egg 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.
- Preheat the oven to 350 degrees F and line the bottom of a 9×9 baking pan with tin foil or parchment paper and then spray the foil/paper with a spritz of non-stick baking spray.
- Layer the cookie dough on the bottom of a 9×9 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 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.
My son wanted these for his birthday celebration! We live at high altitude so I had to make just a few alterations to the instructions. They turned out perfect! I added 1 tsp of water with the flour to the brownie mix. To the cookie mix, I melted the butter before adding it and added 2 tsp of water with the flour to the cookie mix. They turned out great. Be very careful not to overbake!
Can you confirm that you mean to instruct us to let the brownies cool for two hours, ans if after that it’s still not cooked, then bake 5 more minutes? Or are the two sentences out of order? I’ve never tried to bake something after fully cooling it down before so wanted to clarify!
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.”
if the knife comes out not clean after baking, put in for another 5 minutes and then bake!
Hi Gaby, these look amazing! I was wanting to make these in the UK but the measurements are different here, have you by any chance got the measurements for grams?
I dont- I’m sorry
ALWAYS GO WITH THE DOUBLE STUFFED
Made these for my husband for Father’s Day which and they were great and it was fun but also pretty awkward answering the thousands of questions about “slutty” from my 8 year old daughter.
Delicious and the perfect texture!!
These are too good!! I made them in a 9×13 (against the instructions, I know) and cooked for the full 40 mins and they came out great. Your recipes are the best!!
I only have a square glass pan. Still OK?
it’ll bake differently as glass doesnt retain heat as well. So the outsides will poof up a bit more and the middle will take longer to bake
Amazing “Slutty brownies”! Would recommend to everyone who loves baking!
These are insane!! While it looks like a lot of ingredients at first, many are just repeats of themselves as you move between brownie and chocolate chip cookie layers. Mise en place makes this actually super easy to throw together. Thank you!
can you substitute butter for infused coconut oil?
never tried it!
Total winner! So good and so fun!
Love these! But my heart is calling for peanut butter. How can I incorporate some pb to these?
I would swirl some creamy peanut butter into the brownie batter after you pour it onto the cookies.
I use Oreos for half and Reese’s peanut butter cups for the other half. People tend to prefer the pb side! 😀
I have seen where they alternate reeces cups and Oreo
I’ve made these WAY too many times, they’re so SLUTTY LOL. One of our favs thanks for sharing
Can the doughs be mixed a day in advance of baking then refrigerated or no?
sure – I’d just bring it to room temp before baking
I only have an 8×8 and a 10×10 pan. Do you have any suggestions? Should I take some of the batter out and try and fit into an 8×8?
do a 10×10 and reduce baking time a smidge
These were really good, especially when completely cooled to room temperature after cutting. I don’t think they are “too sweet” but I might cut back on sugar next time as I think they would still be good cutting it back a little.
It’s delicious, I had an 8×8 pan and it worked it was just a little raw in the middle but it is still good. I put it in the refrigerator to store it and it was even better cold. I put it in for the full 40 minutes and tested it and put it back in for an extra 5 minutes and after that I let it cool for a little and it was still raw so I put it back in the oven for another 10 minutes and it was still a little raw, I don’t know what I did wrong but it still tasted good
