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. If I keep getting batter on the knife after 45 minutes baking should I keep putting it back in for 5 minutes until it comes out clean?

    1. I'd say 5 minutes more and then take it out and let it sit on the counter and firm up

  2. hello. I am about make 5 pans of these and i was just curious. there have been comments about coco powder, and leaveners. is there a preference on the cocoa powder (baking chocolate, alkalinity) and people have also had an issue with the cookie dough. it seems like there is alot of leaveners in the recipe eggs, bk soda, bk powder????? I am making a x6 batch to make 5 pans so i can yield 20 in each pan, but adding these up ive never used a cookie recipe with so much egg and baking powder and soda. is there a reason? and should i modify this recipe differently if i am making so much?

    1. I use dutch processed cocoa powder! and never had an issue with the cookie!

  3. Thank you for the recipe! I made them for a work event tomorrow. After I let them cool would you recommend I refrigerate until tomorrow?

  4. I tried my cookie batter this way, may help with ppl who had it a bit runny.
    First, I swapped the brown sugar and white sugar amounts. It'll make them softer in the middle. Second, I used a cup and a half of flour, and they were crispy at the edges and held a tad better. I used an 8x8 and lined with parchment. I baked for 40 minutes bc of the pan size and the batter being a tad thicker, and they were amazing. Brownies were gooey in the middle and cookie base was nice and solid with soft center. It was perfect.
    For those who had it runny, might try a higher protein flour

  5. I'm making these for an office bake-off and want to make them "Valentine-y" so do you think sprinkling Valentine's M&Ms on top of the brownie layer would affect the baking at all? I saw the recipe for the Red Velvet version of these but I prefer the OG Oreo flavor. 🙂 Thanks, Gaby!

    1. I'd advise against doubling as the baking time gets crazy when you put it in a 9x13. The sides bake way faster than the middle. I'd just make 2 batches in the 9x9 pan if you need a lot of brownies!! xx

  6. Wow!!!!!! Thank you SO MUCH for this recipe!!!!! I've spent ages looking for the recipe that didn't have that awful brownie mix in it!! ( I find it makes brownies very dry and super boring!)
    When I saw yours I got soooo excited! Not only it has a homemade brownie recipe in it but they look so amazingly YUM too!! Can't wait to make them for my husband's bday party on Sunday!! THANK YOU!!!!

    Shame we only get one flavour of Oreos in England though ☹️ but I'm sure it will be just as delicious with the original ones!

  7. I made these tonight with mint oreos and 1/2 of the pan may or may not already be eaten (spoilers: it is). Love them!!!

    1. you can but it won't work quite as well because a box brownie mix yields more than this brownie recipe so you'll have a thicker brownie layer which will take a bit longer to bake

  8. Great recipe I saw this in the new magazine Jan/Feb 2017 “Untacked” but it says it’s by Steven Berkowitz

    1. really? would you mind sending me an email with a photo as that's stealing and I'd like to send the editor a letter.

  9. Hi I'm making this for a school project and I'm wondering about the brownie layer as the comments above are saying there struggling. Do u struggle because if you do what is it that can make it easier?

    1. I've made it hundreds of times and as long as you let it rest before cutting you'll be okay. I chill them sometimes to make everything set faster

  10. I was hoping to find the recipe for making this into the slutty brownie cake you posted on Instagram. Did u bake each recipe into a layer and then put it together into a layer cake? The photo looked amazing!
