What do I Need for this Recipe?
- 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.
These indulgent brownies are rich enough on their own but become an ultimate dessert when topped with a scoop of vanilla ice cream.
- 8×8 Baking pan
- Mixing bowl
Variations and Substitutions:
- Pan size – if you would like your ultimate slutty 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.
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.
Step 3: To make the brownie layer, combine the mix, eggs, oil, and water in a large bowl and stir.
Step 4: Spread the batter over the Oreo layer.
Pro Tip: Don’t over-mix the brownie batter, stir just until the ingredients are combined. If desired add a handful of nuts!
Step 5: Bake for 45-50 minutes or until you can stick a toothpick in the center of the brownies and only a few crumbs come out.
Step 6: Let the cookie dough Oreo brownies cool completely. Then lift from the pan by the parchment paper and slice it into small squares.
SERVE: Enjoy the brownies by themselves or with ice cream!
- Depending on the brand of brownie mix you are using the ingredients may vary. Check for the exact amounts of oil, water, and eggs that are needed.
- The baking time may vary slightly if you are using homemade cookie dough and/or brownie batter.
- We like our bars on the gooey side. If you want them dryer just cook a little longer.
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 slutty brownie.
It’s simply a racy name to describe this dessert since they are “easy” to make and almost sinful considering the ingredients.
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.
