I feel pretty confident telling you that this is the first, last, and only time you’ll see something on Planet Byn made with mixes. (With the possible exception of Mila’s 1st Birthday Smash Cake in a few weeks, but no one’s going to actually eat that, so I feel it’s justified). (Oops and those Red Velvet Cupcakes from Champagne & Cookies, but no one ate them, so they don’t really count either).

Slutty Brownies are the brainchild of The Londoner who writes “they’re oh so easy, and more than a little bit filthy”. I would also add that you feel quite dirty after you eat one. What’s happening here is a chocolate chip cookie mix pressed into a pan, topped with a layer of Oreos, and covered with a brownie mix. Sure, there are recipes online for homemade versions, but then they’re not so slutty, are they? (Although they would probably taste way better…I’ll get on that).

Update: I did! Check out Slutty Brownies more wholesome twin sister here: Chaste Brownies. And their cousin, Peanut Butter Slutty Brownies!

I made these as a birthday treat for Leianne, along with some Peanut Butter Bacon Cookies. Danielle also made them for Brownie Friday at her work, and people were flipping out!

1 chocolate chip cookie mix (I used PC’s Decadent Chocolate Chip Cookie Mix, try to get that one because Danielle said the one she used was gross)

1 bag of Oreos (or knock-offs)

1 brownie mix (I think mine was just Betty Crocker Chocolate Fudge)


  1. Line an 8×8 square baking dish with tin foil and spray the foil with non-stick spray. Preheat the oven to 350.
  2. Mix up the chocolate chip cookie dough according to the package and press it in the bottom of the pan.
  3. Top it with Oreos.
  4. Mix up the brownie batter (I used the same bowl that the cookie dough was in, in keeping with our dirty, filthy theme). Pour over Oreos.
  5. Bake for 30 minutes. Let cool for a while before slicing.

Okay so I have to make another two batches of these bad boys because they are so popular. Who knew that my coworkers were such dirty peeps!

YES! amazing! i can totally see how these would be snatched up at a bake sale! I’m trying to brainstorm a new version i.e. peanut butter chocolate chip cookie dough on the bottom? golden oreos in the middle?

I made these for our bake sale at work today to wrap up Heart Month. Nothing says heart health like slutty brownies! They were a huge hit, it’s only 10:21, they are all gone and I have emailed out your blog to 5 people already. Thanks for the inspiration!!
I did make the brownie and cookie dough from scratch, nothing fancy but I just couldn’t bare the thought of buying the mix. Taste test reveals that I can’t really taste the difference though.

Lady, these look amazing. They don’t deserve such a harsh name…LOVE IT!

For reference, I used the Betty Crocker chocolate chip cookie mix that comes in a pouch! I’m not really sold on anything that is sold in a pouch!!
