What do I Need for this Recipe?

🍫 Ingredients:

store-bought cookie dough – the kind in the tube
Oreo cookies – we used the regular variety
brownie mix
eggs – use the amount that is listed on the box
vegetable oil – helps to make the best fudgy brownie
water – activates the ingredients in the brownie mixture.

Optional Garnish:

These indulgent brownies are rich enough on their own but become an ultimate dessert when topped with a scoop of vanilla ice cream.

Equipment Needed:

8×8 Baking pan
Mixing bowl

Variations and Substitutions:

Pan size – if you would like your ultimate slu*tty brownies to be a little thinner use a 9×13 dish. My recommendation would be to use 2 tubes of refrigerated cookie dough so they keep their thickness.
Homemade version – the original recipe calls for store-bought ingredients, however, you can use a homemade cookie dough base. Because these are so rich, our personal preference is to go with semi-sweet chocolate chips or dark chocolate chips. Here’s my recipe for the best brownies if you want those from scratch too.
Oreos – Choose your favorite variety! Some prefer to go with Double Stuff Oreos or even birthday cake Oreos.

🔪 Instructions:

PREP: Line an 8×8 baking dish with parchment paper and preheat the oven to 350 degrees.

Step 1: For the chocolate chip cookie layer, press the dough into an even layer at the bottom of the pan.

Step 2: Place a layer of Oreo cookies on top so it covers as much of the cookie dough as possible.

Fun Fact

Originally these brownies were made by Kevin & Amanda years ago and were called the ultimate chocolate chip cookie n’ oreo fudge brownie bars. The Londoner coined the name slu*tty brownie.

Why are they called slu*tty brownies?

It’s simply a racy name to describe this dessert since they are “easy” to make and almost sinful considering the ingredients.

How to store these brownies?

Keep leftovers covered with plastic wrap or tin foil on the counter for 3-4 days or in the fridge for a week. They can also be frozen for up to 3 months.

Notes

Storage:

slu*tty brownies will keep at room temperature for 3-4 days or in an airtight container in the refrigerator for up to one week. Freeze for up to 3 months.

Notes:

You can use a 9×13 baking dish for a thinner slu*tty brownie. I would recommend using two tubes of cookie dough in this case.

Please note – the specific ingredients for the brownies should be followed according to the package instructions/ingredients. The exact amounts of oil, water, and eggs will vary with brands.

You can use homemade cookie dough and/or homemade brownie batter for this recipe. The cook time may vary slightly, but in general, will cook up about the same.

This cook time and pan size produced nice fudgy brownies and chewy cookies. You can cook longer if you like a drier bar.
