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.

A bowl of oreos, brownie batter, cookie dough and a baking pan with cookie dough in it.

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

How to Make Slutty Brownies

A pot filled with brownie batter and 2 eggs.

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 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.

  1. Hi Gaby, I made this brownies but I had a small problems, as some people already mention it here.
    Everything was perfect and following your instructions until I place mold on the oven, 3 layers all in place.
    Once I finished cooking it, I saw that something was wrong, I was able to see parts of the cookie dough on the surface. Even more, when I cut it I saw that also part of the brownie layer ended up at the botom and that the oreo cokies were eveywhere.
    The only thing that I did different from the recipe was that I used a Silicone mold instead of a cooking pan.
    Could it be that because of the silicone mold I got that result?
    Thanks and by the way, despite it was a mess, they were delicious!

    1. Hi!

      I don't think the mold has anything to do with it... but as far as the cookie dough and brownie layers, occasionally the cookie dough around the edges will creep up to the top and peak out a bit - but I've never seen the brownie layer sink to the bottom. Where the parts of the cookie dough you saw on top near the edges of your mold? Let me know and I'll help get to the bottom of this 🙂

    2. when I make these the last 5min I put marshmallows and Carmel, then when I take them out of the oven I put chocolate chips. Yummmmmy

  2. Dear Gaby. You are my hero. My friends and I LOVED these. We ate almost an entire tray. Thank you so much.

  3. Oh, yes! These are the sluttiest brownies ever. Better than Better Than Sex cake even! My daughter introduced them to me and I bout lost my mind! As I am diabetic I immediately took a hit of quick acting insulin and another brownie! OMG! Our local store had BOGO free Oreos that week and I got 12 packages! For future use of course! Please try the Mint Oreos for a wonderfully different taste! I ate mine with Mint Chocolate Chip ice cream! Decadent!

  4. If I need these for Saturday morning but can't make them Friday night, will they keep well if I make them on Thursday?

    Thanks!

    1. Yes absolutely!! Just pop them in the fridge once they've cooled down from the oven!

  5. Tomorrow I am doing a make a wish foundation wish for a girl who has spent the last 6 years in hospitals. Her wish was to have her birthday party at the club I cook at. The cake she asked for was brownies. Me being the way I am wanted to do something less traditional. So to my satisfaction saw this recipe and decided that it would be perfect. I hope I was right. The chocolate I am using is a godiva chocolate. Wish me luck.

  6. OMG. I am speachless. Good thing this is online, because I'm not fingerless, just speachless.
    I'm also drooling, just a little.
    I cannot wait to try these. They may just be perfection.
    Thanks for the recipe for the brownie's, I've had bad luck with homemade brownies.

  7. OMG im in the military and the only problem i see with the brownies is..... How the heck am i gonna fit into my uniform!... They look addictive i cant wait to try them and if it get fat ..... your coming to work out with me righ? ..HAHA

  8. I currently have a pan of these bad boys in the oven (can't wait!) and am I curious about the other half of the cookie dough... how long do I need to bake the cookies?

    1. Gaby,
      I took the brownies (and cookies) to a BBQ and I've never seen a pan disappear so quickly. I will definitely be making these again. Thanks!

  9. Why the foil lining the pan? Why not just butter the heck out of it before pressing in the cookie dough? I've been wondering that. I plan to bake these very soon! 😉

  10. Okay I cannot stop laughing at the name. I mean I fell on the floor and rolled around holding my side from all the laughing. They look wicked good, which seems appropriate given the name.

  11. I made these recently and they came out really yummy. I did make a few revisions though. I used a combination of white and light brown sugar with the brownies and added melted chocolate in there as well. (Just because I wanted a really moist, fudgy brownie. Plus I really wanted a deeper chocolate flavor) I also added grated chocolate to the cookie dough (Yup, chocolate makes everything better) and walnuts! These were so sinfully delicious! Even before they were baked I can already tell they'd turn out really well. Thanks so much!! Everyone loved them! Next time, I'm gonna try a cream cheese filling instead of Oreos! 😉

    1. Wow! Maia, I love the way you think! Chocolate makes everything better and there is no such thing as enough...am going to try it your way...as soon as the temperature drops below 70 degrees or so...(or you send me some out of pity...LOL).

  12. Hi Gaby,

    I'm in a time crunch -- could I use a tube of cookie dough and a box of brownie mix? Can't wait to try. Thanks!

  13. hi!

    may i know how many grams is 1 cup of butter? i tried making this afternoon (with 226g butter which i convert online) and it was all good except for the cooking dough which was too soft & oily, it didnt really set well. i bake for as long as 50mins+15mins more but it's still the same.

    i used a 10x10 pan & i actually use up all e dough instead of half, is that the problem? or 226g butter is too much?

    pls advise! thank you.
    btw the brownies is still delicious! 😀

    1. Hi Stefani - thats the right conversion for the butter so 226 is good to go! Did you melt the butter? That could have make it a little oily. And if you use all the cookie dough, that will definitely affect the baking time. Do you have a smaller 9x9x9 pan? It really makes a difference in baking times depending on the pan size. Hope this helps!
