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. Almost every blogger has made some version of this recipe but if you’re looking for the BEST Slutty Brownie recipe, look no further.

Slutty Brownies FROM SCRATCH

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 when really, they’re just outrageous and amazing. (Slutty isn’t really a word I like to use, anyway.)

However, people DO search for them and since I’ve been making them for years I figured I needed to finally post the recipe. I couldn’t call them Brookies (although basically, that’s what they are) because I already have a recipe for those.

Let’s just agree the name isn’t great but the bars ARE.

Besides Slutty, we could also call these one of many other names: Chocolate Chip Oreo Brownies, Crazy Brownies, ULTIMATE Brownies, Ultimate Slutty Brownies…and so many more names.

What are Slutty Brownies?

I’ve seen SO many recipes for these cookie bars. Some use a refrigerated cookie dough for the chocolate chip cookies. Some use a box brownie mix. Some use both!

I decided to make slutty brownies from scratch because I love my chocolate chip cookie recipe and my brownie recipe SO much.

Because you’re making two recipes in one, this recipe does take a little bit of time, but they’re worth every minute.

Slutty brownies step by step
  • They’re easy cookies that start with melted butter, so you don’t need a mixer.
  • Stir together butter, brown sugar, and granulated sugar. Then stir in an egg, vanilla, baking soda, and salt, and then the all purpose flour. Chocolate chips are last – but not least!
  • Normally when I make these as cookies you have to chill the dough, but when you’re making cookie bars you can skip that step.

Brownie Layer

My favorite brownie recipe has three important things about it:

  1. It’s one bowl, one spoon, no mixer,
  2. It has baking chocolate you melt with the butter,
  3. AND it has cocoa powder you add after you stir in the sugar and eggs.
  4. Once you make the brownie layer, you’re ready to assemble!

Tips for how to make Slutty Brownies

  • You’re going to want a 9×13-inch pan for this recipe, one with 2″ sides. Use metal or glass, whichever you prefer.
  • 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.
  • First, press the chocolate chip cookie dough into the bottom of the pan.
  • Then, top with about 24 Oreos. I used regular Oreos but you could use double stuff or any flavor you want.
  • Top the Oreos with the brownie batter. Spread it evenly to cover the cookies.

How to know when Brownies are done

Once the top looks solid and no longer wet, these are done. You can do the toothpick test around the edges, but it’s best to use your eyes – when it looks done on top, they’re done.

Most importantly: if you want them to set so they look pretty when sliced, let them cool completely.

First of all, I suggest small squares for serving. These pack a punch and they’re perfect dessert for a crowd.

Store in an airtight container on the counter, or freeze for up to one month. Learn how I freeze all my desserts!

FAQs

Why are they called Slutty brownies?

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.

Can you freeze brownies?

Freeze these in an airtight container for up to 3 months.

Can I use store bought ingredients?

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!

  1. 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.

  2. 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!

    1. 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.

  3. 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!

  4. These did not turn out, I wish I had read the comments before wasting money and my time. The brownie batter never set and was still molten like others said. It was too much batter for the size baking dish.

      1. Metal, I left it in for about an hour and the inside was barely baked and the top was totally separated and broke apart when cutting. I think if there was less batter it would cook better. Cookie to brownie ratio is off. Didn’t look pretty lol

      2. Awesome recipe, I followed this to a T and it came out delicious. I baked my brownies for 40 minutes, next time I will only bake for 35. Thank you!

  5. Made this with my 14 year old. Used the converted measurements from grams and it didn’t cook at all. Total molten. Wasted most of my baking ingredients as it had to be thrown away! Please recheck your conversions, especially for the sugar.

    1. If it was totally molten that means it wasn’t baked all the way and needed to bake longer. The gram measurements are the exact same I use for all my recipes.

    2. Same thing happened to me! I left it in the oven for over an hour. Outside got hard as a rock and inside was still liquid. I also used the gram measurements.

  6. I made this recipe this evening and it turned out exactly as planned! I just used parchment only. I also used salted butter and doubled the salt in every case. I was baking bread at the same time, so my oven was at 425F and I kept these in for 30 minutes. I can’t wait to experiment with other cookies as the middle layer now!
