Slutty Brownies are the most decadent and outrageous bar cookie you’ll ever try: chocolate chip cookies on the bottom, brownies on the top, and Oreos in the center. Normally this recipe is made with pre-packaged dough and box mixes but my recipe is completely from scratch. I don’t know who came up with the horrible name, but these are really EPIC brookies!
Okay let’s just put it out there that I’m not in love with the name of these brownies. It’s a little awkward to call them slutty because that’s a horrible word. Maybe we turn the word into something amazing? People do search for the term (I think some blogger (I believe it was Kevin and Amanda) created it years ago and they went viral and the name stuck) and I’ve been making them for years.
These are an epic from scratch chocolate chip cookies on the bottom, Oreos in the center, and homemade brownies on top – they’re SO so good!
Ingredients Needed
- Butter: I always use unsalted butter, but salted may be substituted by reducing added salt. I use melted butter in both layers.
- Sugars: You need both granulated sugar and brown sugar.
- Baking Chocolate: For the brownies you’ll need unsweetened baking chocolate, which is found in the baking aisle.
- Cocoa: I use regular unsweetened cocoa powder, but dutch process may also be used.
- Oreos: You’ll need about 24 Oreo cookies or similar sandwich cookie for that layer.
Slutty Brownies Variations
- Make a semi-homemade brownie: Use a large roll of cookie dough (32 ounce size) in place of the chocolate chip cookie recipe and/or a box of brownie mix (make according to box directions) for the brownies.
- You can make this with ANY kind of cookie dough from the store – any flavor. Or use my double chocolate chip cookie recipe or even peanut butter cookies.
- You can use ANY flavor Oreo Cookie!
Chocolate Chip Cookie Layer
1. Melt butter and stir in both sugars in a large bowl. You don’t need to use an electric mixer, but you can. Stir in egg, baking soda, salt, and vanilla extract.
2. Stir in flour then stir in chocolate chips. At this point, you’ll press the dough into the bottom of a 9×13-inch baking dish.
Brownie Layer
3. Melt baking chocolate and butter until smooth. Make sure to use a large bowl that is microwave safe, and stir every 30 seconds while melting.
4. Stir in the sugar, cocoa, salt, and eggs until smooth. No mixer needed unless you want to use one! Then stir in the flour.
Assemble the Layers
5. Place a layer of Oreos evenly over the cookie dough in the baking pan.
6. Carefully spread the brownie batter over the top of the Oreos in an even layer. Then bake until the brownies are no longer glossy on top.
Storing Instructions
- Store cooled Slutty Brownies in an airtight container on the counter, or in the freezer for up to 3 months. Learn how I freeze all my desserts!
Expert Tips
- You’re going to want a 9×13-inch pan for this recipe.
- You can also make these in muffin tins if you want Oreo Cookie Brownie Cupcakes!
- I like to cover the pan with foil and spray with nonstick cooking spray to make removal and slicing easier.
- These take quite a long time to bake because they’re so thick. You know brownies are done when the top is solid and no longer wet looking. The toothpick test can be done 2 inches from the edge, but it’s best to use your eyes for this.
- Cool completely before slicing.
FAQs
This recipe originated with a blogger who called them something different, then another blogger made them and re-named them for shock value – and they went viral. Let’s make Chocolate Chip Cookie Oreo Brownies trend so we can skip the bad name of them!
Feel free to swap out refrigerated cookie dough (one log) and/or one box brownie mix (plus the ingredients to make the brownies). But I love this from scratch version best!
These will take quite awhile to bake. You know they’re done when the brownie layer is cracked and dry looking on top – you can use a toothpick to check just the top layer 2-inches from the side of the pan.

These tasted amazing and the recipe was not messy and very easy to follow. However, the baking time was too little. I baked it for 35 minutes, but the brownie batter was not set. I kept pulling it in and out of the oven until it was less uncooked. It took almost an hour for this whole process. I would say to keep the brownies in the oven for 50 minutes, then check on them every 3 minutes until they’re set. Other than the oven situation, I loved this recipe.
Why do you have to use the name “slutty”. It is such a derogatory name towards women. It would taste just as good with another name!
As I mention in the post, I did not invent the name of these brownies and don’t like the name. But this is what people search for.
I made these and they came out great! I did read the comments before baking. I used a metal pan and cooked them at a lower temperature. I cooked them at 325 for 30 minutes, they weren’t quite done, so I put them back in and checked them every 5 minutes. They came out perfect, thank you!
so glad you liked them!!
