The Ultimate Slutty Brownies are made with our tried and true chocolate chip cookie dough, a center layer of Oreo cookies, and are topped off with our famous brownie recipe that has survived dozens of blind taste tests. These layers of dessert goodness are then finished off with crumbled Oreo and chocolate chips for the ultimate over the top dessert!

Bird's eye view of Slutty Brownies cut into squares.

Slutty Brownies rose to internet fame when The Londoner came up with the viral name to describe a brownie recipe with layers of cookie dough and oreo on the popular website Kevin and Amanda. We’ve taken this internet sensation and combined it with our now famous base recipe for The Best Brownies Ever to create the ultimate slutty brownie.

What makes our recipe the best? We first conducted an extensive blind taste test of every brownie mix on the market and pitted it against our own brownie recipe. When our recipe came in third place, we went back to the drawing board to create a new recipe that could beat them all. After 20 rounds of recipe development, we created a new brownie recipe that was able to withstand our blind taste test, proving itself to be the best brownie recipe ever.  We’ve taken our tried and true chocolate chip cookie recipe we’ve been using for over 25 years, layered on some Oreos, and topped it off with our new best brownie recipe. It is perfection in every layer. We’ve also added crushed Oreos and chocolate chips on top for the ultimate finish. This over the top dessert is sure to be a favorite!

PRO TIP: Be sure to line your pan with parchment paper. Not only will this prevent your brownies from sticking, it also creates a nice little carrier that allows you to easily remove your brownies in one solid slab. This is especially important for a recipe like this that involves lots of heavy layers.

Line Brownie Pan with Parchment Paper
Press Cookie Dough into Even Layer in Pan
Create layer of classic Oreos or double stuffed Oreos on top of cookie dough
Spread brownie batter on top of oreo and cookie dough layers

Do you have to use regular Oreos for slutty brownies?

While slutty brownies are traditionally made with classic or Double Stuffed Oreos, that doesn’t mean you can’t get creative and give other flavors a try. The S’mores, Red Velvet, Golden, and some other flavors of Oreos should go great with this recipe. Be warned that the crazier Oreo flavors like watermelon will not be the best match.

How long do I need to let slutty brownies cool before eating?

Waiting for the brownies to cool before eating them is probably the hardest part of any good brownie recipe. Letting your brownies cool completely before slicing into them is not only for safety, but will improve the texture and taste of the brownie. Brownies are still cooking when you pull them out of the oven. They need this cooling time to finish baking, firm up, and become the tasty treat you love.Be warned that should you be unable to resist the warm brownie, the center may still be undercooked and you will not be able to get clean slices out of the pan.

I’ve made this more than once and it always tastes great! I’m planning to make it again, but I only have bread flour… Is it okay to use it instead?

Bread flour would result in a denser and more chewy brownie.

AMAZING. I made these dairy free (parve) by using the same amount of Earth Balance instead of butter in the cookie dough recipe, and then substituting vegetable oil for butter in the brownie recipe. I let my cookie dough sit in the refrigerator for 72 hours. So good and a serious hit at the meal I brought them to. 🙂

I don’t know what I did but when the brownie layer looked done and baked the cookie dough layer underneath was undercooked. I am scared to put them back in the oven out of fear of burning the top layer.

I made this for my family and they loved it. We ate straight out of the oven paired with some ice cream. The recipe is super easy to follow no need to be an expert to do it. Definitely recommend it.

Can I make these with dairy free butter? Will they taste the same?

Reply to  Kiki

Dairy free butter does not always bake well. It definitely could affect the taste. If you’re going to try dairy free butter, be sure to use dairy free butter sticks, and not from a tub.

Can I use glass or Tins that are disposable?

Reply to  Jean

Yes, you can use either. We still recommend lining your pan with parchment, no matter what type of pan you use.

Good is good! Try some icecream on top to cool them down enough to eat right out of the oven!

Oh My Word! These look so good I’ve gained 5lbs just looking at the pictures ?
