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

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. I thought you could crush the oreos.. I made a batch with the oreos crushed the tasted ok but didnt have the layered look..

    1. Hi Shannon,

      I've never tried it with crushed oreos - I bet it tastes the same - but ya you won't get that layered look. I'm going to try it thou! I bet it could be fun 🙂 Or another brownie recipe with crushed oreos!!

  2. im so excited to bake these for my friends birthday..i am just going to use store brownie mix and store cookie dough. will the cookies be burnt for cooking it for 45 mins?

  3. I am attempting to make these brownies with a box brownie mix. Because your recipe uses a 9x9 pan, should I cut the box brownie mix in half or can I use a 9x13 pan anyway and make the cookie dough part thinner?? Should I double the cookie portion of this recipe for a 9x13 pan?

    1. you should use the 9x13 pan and just have a slightly thinner layer of cookies and use the full amount of box brownies!! Happy Baking 🙂

  4. These are ridiculous in a good way. They are also about the richest thing in the world. I can only eat about half the pan. They need a new name, how about Chiporeonies?

  5. Good stuff, but the brownies were undercooked and gooey. I used a 9x9 pan (metal) and cooked for almost 45 minutes because my knife wouldn't come out clean. Finally took them out because I didn't want the cookie layer to burn. (It was perfect.) I let these cool completely, but they completely fell apart due to the gooey brownie layer. More than half were thrown away because I wouldn't serve something so sloppy and undercooked to anyone.

    Thoughts?

    1. hmmmm that's interesting. How long did you let them cool? Sometimes it takes a while for the brownie and cookie layer to set up. Let me know and we'll get to the bottom of it!

  6. What degrees do you use? Farenheit or celcius?
    If Farenheit, how many degrees shoud I have in celcius?
    Hug, Moa 🙂

    1. Hey Taylor, I'd keep an eye on it... since yours will be a little less thick but wider, it might still take the same time... but you just want to look for the brownies to be slightly gooey in the center and then take it out and let it cool completely and stop cooking 🙂

  7. These look amazing!! I'm thinking of making these for next weekend when I visit my best friend for a Halloween party weekend. Perfect for us and her roomies!
    Why Tin foil, did you find parament paper stuck to the cookie dough?

  8. I've had mine in the oven for an extra 15 minutes now - and the insides still aren't done. they are runny and gooey inside. I made regular cookie dough, and used a boxed brownie mix for the sake of time. I am using a 9x9 metal pan, lined with foil and sprayed with Pam. Any thoughts why they won't cook?

    1. Hey! I'm not sure why they aren't cooking. How long does the brownie batter mix say to bake for? My brownie recipe cooks a bit faster than the box ones do, so perhaps that's part of it?

  9. I tried this recipe with a glass pan and the dough layer turned out uncooked and sloppy 🙁 the brownie was amazing though. I may have messed up the conversions to grams though.

    Would a tin be better?

    1. Hi,

      I dont think the tin vs. glass pans would make a huge difference - although I do use tin plans in my kitchen. I would double check on the conversions since I've made these a ton of times and have never had them uncooked. I'll see if I can do the metric conversions and add them to the post 🙂

  10. i love making this recipe! And this we are in the month of October and Halloween is right around the corner. i decided to use Halloween oreos! tastes the same and adds a little more color to this amazing slutty brownies!

  11. Those look absolutely delicious! One of my favourite kind of brownies are the double fudge ones my Mom makes whenever I come home from overseas travel. These are definitely slutty in a good sense 🙂
