Also known as Slutty Brownies, these brownies are the only thing that sound good after being sick for 3 days straight and not being able to eat. Brownies and pizza… and I’m having neither. I’m actually doing good today, I was able to eat 3 crackers and some jello.


This recipe isn’t the super fancy homemade one.. This recipe requires box mix because that’s all I could probably muster up at this moment.


For the brownie layer
1 (18 ounce) box brownie mix, prepared and unbaked

For the Oreo layer
1 (15 1/2 ounce) package Oreo cookies

For the chocolate chip cookie layer
1 (18 ounce) roll ready-made refrigerated chocolate chip cookie dough


1 Pre-heat your oven to 350 degrees.

2 Line the bottom of an 8×8 baking pan (I used a Pyrex pan) with tin foil and then spray the foil liberally with baking spray.

3 Make the brownie layer per box instructions (without baking). Set the batter aside.

4 Get cookie dough ready

5 Time to Assemble!

6 Start by gently pressing the cookie dough into the bottom of the pan, making sure to create an even layer. (I found it helpful to use the back of a 1-cup measure cup)

7 Then add a layer of Oreos on top of the cookie dough. Nudge them as close together as possible without overlapping.

8 Pour the brownie batter on top of the caramel-Oreo layer. Use a spatula to make sure it’s even.

9 Bake for 30-35 minutes.

10 Test with a knife to see if the center is done. It’s OK if the knife has some brownie on it. It’s easy to over-bake the cookie layer if left in the oven too long.

11 Although you can scarf these right away (they’ll be crumbly but delicious and gooey!), they actually get better with age. Let them rest for several hours for easier handling and serving.

12 *Note: Prep time is reduced if using boxed/ready-made mixes.

    Yum! :) Glad you’re progressing!

    Thank you Wendy! I think the fever is finally breaking… finally.

  • Wendy

    Yay! That’s good to hear.

  • Natalie

    I have made these before and love them! I saw you mentioned caramel – do you add sundae topping caramel? I didn’t see it on the ingredient list. Yum!

  • Simon

    Can I freeze these for 2 days or refrigerate for 2 days

  • Vee

    There is no mention of the caramel in the ingredients so I didn’t purchase it. Thankfully it turned out great without it.

  • Mike

    Tried making these, but 30-35 minutes not nearly long enough. Mine are going on 50 minutes now. Fork breaks right through the hard top but it’s still complete goo underneath.

  • Jennifer

    I’m also having a hard time getting the middle of these brownies to set. Top is fine, and then it’s still brownie batter by where the Oreos are. I don’t even know how long they’ve been in… 40 minutes or so?? Any suggestions would be most welcome.
