Thick and delicious slutty brownies will be your new favorite dessert bar recipe. Made up of a layer of chocolate chip cookie dough, Oreo cookies, and brownie batter these bars are everyone's favorite!
It has been years since I made these brownies, they became popular back in like 2011/ 2012 when Amanda made them famous on her site. The internet gave them their silly name.
I recently remade my version of them for a party and after how well they were received I knew I had to create them for the blog.
Everyone loves these brownies. You cannot beat a layer of chocolate chip cookies topped with a layer of Oreo cookies then finally brownies on top. These bars are sweet and chewy.
Unfortunately, they are the kind of bar that you cannot stop eating, they are addicting. I speak from experience, when I took them to a beach party and they all disappeared quickly I was ever so lucky to have stashed one in my purse haha- sugar addict much!? LOL
Another dessert recipe I have no control with is my chocolate cheesecake recipe.
Let's get to the brownie recipe.

🍪What are the ingredients
There are three components for slutty brownies
- Chocolate Chip Cookie Dough- you could use store-bought or I have an easy 5-minute recipe below
- Oreo's- You can use double stuff or regular. I use regularly since I always have them on hand for making crusts.
- Brownies- I prefer to use my thick and chewy brownie recipe, you could use your own favorite recipe, or you could easily use a boxed brownie mix- for this recipe, I only make a 9X9 pan so make sure your mix is not for a 9X13 pan.
If you want to use my chocolate chip cookie recipe below you will need:
- Unsalted Butter
- Brown Sugar & Granulated Sugar
- Egg and Egg Yolk
- Pure Vanilla Extract
- All-Purpose/ Plain Flour
- Baking Soda
- Salt
- Chocolate Chips- my favorite to use are these Callebaut Chocolate Callets
Don't miss my skillet brookie recipe!
Baking is a science and to really achieve the best results I highly recommend investing in a kitchen scale. This OXO Kitchen Scale is the one I use and is also the number one recommended kitchen scale by Cook's Illustrated. Think about it -what one person scoops into a "cup" is completely different from what someone else scoops!
📖How do you make slutty brownies
Preheat your oven to 350F/180C and line a 9X9 square pan with foil, making sure to let the foil overhang on the edges to help pull the brownies out later. Make sure to grease the foil heavily.
In a large bowl add the melted butter and sugars, mix until fully incorporated. Add in the egg and vanilla extra and whisk until fully combined.
Add the flour, baking soda, and salt and gently use a spatula to fold into the wet ingredients. As there are a few flour streaks left add the chocolate chips and gently fold into the batter.
Pour batter into prepared pan and line the Oreos in one even layer on top of the cookie dough.
The brownie recipe for these slutty brownies is my thick and chewy brownies made with cocoa powder. Check out this post for step-by-step photos on how to make this easy brownie recipe.
Pour the brownie batter evenly over the Oreo layer. Bake for 35-40 minutes. You want a toothpick in the center to come out with moist crumbs, not completely dry.
Place the pan on a wire rack to cool completely before cutting. This is a must, let the brownies cool a minimum of 2 hours before attempting to cut. Store the brownies in an air-tight container on the counter for up to 4 days.
I like to cut the pan into 4 sections across and 4 sections down to create 16 equal pieces. The layers are just beautiful!
Because these dessert bars are quite tall you could easily cut them into 6 across and 6 down for more servings.
I may or may not think that these slutty brownies are enhanced by a big ol' scoop of vanilla ice cream.
Either way, they are the bomb. Enjoy!!
⏲️ Can you make slutty brownies ahead of time?
Totally, since these brownies need a couple of hours to set before slicing they are the perfect recipe to make the night before serving. Letting them sit overnight helps ensure they are completely set up for slicing.
I have also frozen some baked and cooled brownies, frozen treats are my favorite. Let them sit at room temp for 20-30 minutes to thaw out.

Instructions
Chocolate Chip Cookie Layer
- Preheat your oven to 350F/180C and line a 9X9 square pan with foil, making sure to let the foil overhang on the edges to help pull the brownies out later. Make sure to grease the foil heavily.
- In a large bowl add the melted butter and sugars, mix until fully incorporated. Add in the egg and vanilla extra and whisk until fully combined.

Brownie Layer
- In a large pot add the water, butter, sugar, and cocoa powder. Cook on medium heat for 2-3 minutes until it is all combined together, the mixture will look weird and not liquidy enough, that is fine. Then add the oil and vanilla extract. Cook on low for an additional minute and mix to combine everything.
- Take off of the heat, let sit for 5 minutes then add the egg and egg yolk. Whisk to combine.
- Add the baking soda, salt, cornstarch, and mix to combine. Gently add the flour by using a spatula to fold in until just combined, just before there are no flour streaks add your chocolate chunks/ chips. Do not over mix, this will affect the end product.
- Pour the brownie batter evenly over the Oreo layer. Bake for 35-40 minutes.
- You want a toothpick in the center to come out with moist crumbs, not completely dry. Place the pan on a wire rack to cool completely before cutting. This is a must, let the brownies cool a minimum of 2 hours before attempting to cut. Store the brownies in an air-tight container on the counter for up to 4 days.

Kayle (The Cooking Actress) says
Slutty brownies never get old and I love that yours involves from scratch recipes for the cookie dough and brownie batter!
★★★★★
Steph says
Can you make it without the oreos or is it important to divide the different batters?
Elizabeth Waterson says
Hi Steph, they should bake up just fine without the Oreos but I have not done it myself. Let me know if you have any other questions or if you do try them! XX Liz
Diana says
I tried to do it, but when I took them out of the oven the cookie dough and the brownie mix all together, I don’t know what I’m doing wrong. 🙁 the cookie dough went up instead of staying down :,(
Elizabeth Waterson says
Hi Diana, I am so sorry you had a problem with the recipe. I truly don't know what you could have done wrong, I just made these on Friday with my niece and nephew and they turned out perfectly. The cookie batter does kind of rise up a little over the Oreos but you should still have the layers.
Mariann Brooks says
I made a halloween version with halloween sugar cookies, halloween Oreos and brownie mix, plan to top with orange frosting and sprinkles!!
Elizabeth Waterson says
HI Mariann that sounds fantastic!!! thanks for sharing, If you love them would you mind leaving a star rating and review next time, please!! Thank you and Happy Halloween! XX Liz

Thank you so much for coming back to review the recipe Alannah, it really means so much!! And I am so happy to hear they are a favorite!! Take care XX Liz
Anisha Dawar says
Hi, could you suggest a replacement for the Eggs, with the desired measurements. Thanks
Elizabeth Waterson says
Hi Anisha, thanks for reaching out. I would try using a flax egg, you could try this recipe. I would use two flax eggs for the brownie recipe and one for the cookie recipe. I have never done this myself but that is what I would personally try. Please let me know if you have any other questions and if you try it and make the brownies. Thanks XX Liz
TW says
Why "slutty" brownies? Don't we aready live in a society where just about EVERYTHING alludes to sex. No wonder our children are becoming obsessed with sex and engaging in pre-marital sex at earlier ages. I see why though: Adults are forcing this "trash" mentality/society on our kids. Thanks for the recipe, but come up with a classier title. next time.
Thank you, and have a good day.
Elizabeth Waterson says
Hi there, I understand your concern and appreciate you reaching out. I didn't come up with the name of these brownies, but I know it was just a joke not meant to offend anyone. Liz
Kaila says
This recipe gave me a fake ID and sent me to the bar to pick up on older men, pls help these brownies are FORCING me to be promiscuous when I should be in Sunday school
★★★★★
Christine Ponder says
TOTALLY agree. I'm not making a big campaign out of it, but the name is garbage. Rename it.
★★★★
Nicki says
Hi,
If I use store bought cookie dough for this recipe, how much dough would I need to use?
Elizabeth Waterson says
Hi Nicki, thanks for reaching out. I haven't used store-bought cookie dough in ages but I think like the pre scooped ones come in a 24 cookie pack- 6X4? If so I would probably use the whole pack, or just shy of the whole pack. Let me know if you try it. XX Liz
Mailin says
Hands down the BEST brownies I’ve ever had!!!!! They were soft and chewy and absolutely decadent 5/5 will definitely be making it again!

Mysti says
So I have made this recipe 3 times now... Once with your from scratch method and once with store bought (because I was in a hurry)... They both came out AMAZING!!! For the third time, I decided to try nutter butter cookies instead of oreos, and lemme just tell ya- GAME CHANGER! Omgoodness... One of the best things ever!!
Thanks for my new "most requested" pot luck addition!
★★★★★
Elizabeth Waterson says
Thank you so much for coming back to rate and review the recipe Mysti, I am so grateful!! So pleased to hear you have enjoyed this recipe multiple times!! I can't wait to try it with nutter butters!! Happy New Year! XX Liz
La La Lisa Korenko says
Like Mysti wrote about adding Nutter butter cookies- Uhhhh-mazing!!!! I also used peanut butter chips rather than chocolate. My husband is a peanut butter freak. Needless to say it passed his taste test. I think this recipe has endless possibilities. I think a Rocky road flavor/flare is next. add some nuts to the cookie dough, add marshmallows to the oreo layer and maybe some marshmallow and chocolate sauce drizzled on the top. This one is screaming to be served warm with a scoop of vanilla ice cream.
★★★★★
Elizabeth Waterson says
Thank you so much for coming back to rate and review the recipe La La Liisa, I am so grateful!! I seriously need to try the nutter butter version, I think my niece and nephew would go nuts for it!!! And yes I often have one of these warmed up with ice cream!! SOOOOOO GOOD!! XX Liz
Dana says
These taste amazing ! I’m
Not the baker at all!! But I needed to show how awesome I am at my boyfriend’s best friends house for dinner tonight, looked up a cool Recipe on Pinterest and found this, made em last night and I was shocked how good they came out! Only thing is, is the choc chip layer supposed to look almost translucent? :/ not sure why but it does and it’s def cooked! I left it in oven 50 min!
★★★★★
Elizabeth Waterson says
Hi Dana, thanks so much for coming back to star rate and review the recipe, so glad you enjoyed them! I am not quite sure what you mean by translucent? You can always reach out to me via DM on Instagram and can send photos so I can help troubleshoot there! XX Liz
Tina Marsella says
Hi... just wondering if these can be made in a 9” round pan? If yes how long should I bake it? Thanks for any help
Elizabeth Waterson says
Hi Tina, thanks for reaching out. You can use a round 9-inch cake pan just make sure it's 3 inches tall/ deep. The bake time is the same. Please let me know if you have any questions and if you try them, I would love to know what you think! XX Liz
Michelle says
Oh my GOD. All my favorites in one. So sinful! The best advice ever is to freeze these (so you don’t eat the entire pan at once) and just heat up one at a time. These are a serious treat.
★★★★★
Elizabeth Waterson says
Finding these in the freezer is the best!! I just moved and half my freezer is frozen desserts LOL!! Thank you for coming back to rate and review the recipe!! XX Liz
Kristie says
Can you make this recipe ahead of time without baking it?
Elizabeth Waterson says
Hi Katie, I have never tried that, I would guess you could maybe make it an hour or two ahead of time and leave it covered in the fridge but beyond that, I wouldn't know so sorry! PLease let me know if you try how you get on! Take care. xX Liz
Erica says
I love making these! I like to top them off with some marshmallow fluff with crushed Oreos on top as well. So yummy
★★★★★
Elizabeth Waterson says
Hi Erica, adding the fluff sounds so good! I need to try that! Thank you for reporting back! 🙂 XX Liz
