I’ve been wanting to post these Slutty Brownies for YEARS but I just never got around to photographing them. But I’m glad that I finally did because HOW FUN are these!? I’m still deciding how I feel about the name but it’s what these are traditionally called so we’re going with it, friends! And I’m not even including the nutritional info with this one because no one needs to see that. LOL!

These are a fun, every once in a rare while kind of dessert :) BUT, they’re also so incredibly delicious and great shared with a crowd.

Ingredients you’ll need

This slutty brownies recipe is completely from scratch. It’s also egg-free, dairy-free, and completely VEGAN! Here are the ingredients you’ll need to make it:

  • Cookie dough: 1 batch of my vegan chocolate chip cookie dough. This is a classic chocolate cookie recipe that results in a soft and chewy base.
  • Oreos: You can use double stuffed Oreos or regular, your choice! You’ll need about 24 Oreos.
  • Brownie batter: 1 batch of my vegan brownie batter. Perfectly gooey and rich!
  • Flaky sea salt: Optional but I think flaky sea salt over brownies is the perfect finishing touch.

Variations

  • Baking chips: My chocolate chip cookie dough recipe uses dairy-free chocolate chips and chunks. Feel free to use your favorite variety! Experiment with white chocolate, milk chocolate, semi-sweet chocolate chips, dark chocolate, mini chocolate chips, mint chips, butterscotch or even peanut butter chips.
  • Oreo flavors: There are always new Oreo flavors coming. I prefer the classic white icing Oreo and even double stuff but there are mint, chocolate, peanut butter and golden. Mix up the Oreo flavors depending on the time of year or holiday!
  • Add frosting: To really take these to the next level of indulgence, you can add frosting. Top with a thick layer of Chocolate Vegan Buttercream Frosting or another favorite. Oreo frosting would be quite delicious!

How to make this recipe

While slutty brownies do take a bit of time to assemble, the whole recipe is honestly very easy. They start with a batch of my vegan chocolate chip cookie dough. Then, a batch of my vegan brownie batter. Here’s the process:

  1. Prep: Pre-heat the oven to 375 degrees F. Line an 9×9-inch baking pan with parchment paper and spray with nonstick cooking spray.
  2. Make the cookie dough base: Make the cookie dough according to the directions and press it evenly and firmly into the bottom of the prepared pan.
  3. Add the Oreo layer: Top the cookie dough with the Oreos, breaking some in half as needed to fit in the pan.
  4. Make the brownie topping: Make the brownie batter according to directions and pour it on top of the Oreos. Spread the batter out evenly.
  5. Bake: Place in the oven and bake for 40-45 minutes or until a toothpick comes out clean. Let rest for 1 hour before slicing into the brownies (I know this is hard but trust me!). ENJOY!

Helpful tips

  • Fit the Oreos: When assembling, it may be necessary to break some of the Oreos, so they fit in a single layer in the pan.
  • Use pre-made dough and boxed brownie mix: To save a bit of time, feel free to use store-bought cookie dough and boxed brownies. I’ve made them that way before and they turned out amazing as well! So, choose your own adventure.
  • Let cool: It’s very important to let the brownies cool for at least 1 hour before slicing (a little longer is even better). If you try slicing them while still hot out of the oven, you’ll have a gooey mess.

Frequently asked questions

What are slutty brownies?

Slutty brownies are basically chocolate chip Oreo brownies with a base layer made with chocolate chip cookie dough, then a layer of Oreo cookies in the middle and brownie batter as the top layer. The combination of flavors and textures is irresistible!

Why are they called slutty brownies?

After doing a little research, I learned that these super indulgent brownies were invented back in 2011 when Kevin & Amanda posted the original recipe. At that time, the recipe was named Cookie Dough Oreo Brownies. They became a viral sensation and the internet ended up changing the name to Slutty Brownies.

Can the brownie layer go on the bottom?

I would recommend sticking with the recipe as written with the cookie dough on the bottom. The cookie dough layer is sturdier and bakes a little quicker, so it makes a good base to hold the Oreos and brownie layer.

Are Oreos vegan?

Most Oreo varieties are vegan and do not contain any milk or other animal ingredients. These include: Classic Oreos, Golden Oreos, Double Stuff, and Chocolate Cream Oreos. The only Oreos which are not suitable for vegans are the Peanut Butter flavored cookies, which contain milk.

Storage recommendations

  • Storing leftovers: Store slutty brownies in an airtight container at room temperature for up to 5 days.
  • Freezing: Once the brownie bars have cooled, use the ends of the parchment paper to lift the bars out of the pan. Leave the bars uncut and wrap the entire batch in plastic wrap then aluminum foil. Freeze for up to 3 months. Defrost in the refrigerator before cutting and serving. You can also individually wrap the bars and freeze them too!
