No-Bake Chewy Oreo Bars are dessert bars that are made with a mixture of chopped Oreo cookies, mini marshmallows, and butter. It’s a simple recipe to throw together for a potluck or anytime you need to bring a dessert or treat to share. Better yet, the bars are made with just three ingredients and are a no-bake dessert, so there is no need to turn on the oven! Be sure to check out my other No-Bake desserts for more tasty treats!
Ingredients & Substitutions
As I stated above, this recipe is made with just three simple ingredients!
Oreos: I went with the double-stuffed Oreo cookies in this recipe and chopped them up with a knife, filling and all. Crushing them or using a blender would have made the pieces too fine. (But, if you wanted smaller crumbs in the bars, you could still add bigger chunks of Oreos on top.) You could also use regular stuffed Oreo cookies or a combination of the two.
Marshmallows: I used a 10.5-ounce bag of mini marshmallows. If you use regular-sized marshmallows, you would need approximately 40 of them to equal the bag of mini marshmallows.
Butter: Use salted butter that is at room temperature.
Can I Use a Different Size Pan?
I made the Oreo Bars in an 8×8-inch baking dish. You could use a 9×9-inch pan if that is the smallest you have on hand. The bars will be a little thinner, but I don’t think anyone will complain; they will still be a tasty treat!
How to Store Chewy Oreo Bars
Store the bars in an airtight container at room temperature. They are best enjoyed within three days of making them. After that, they can begin to harden.
Can I Freeze Chewy Oreo Bars?
No, I would not recommend freezing these bars. The marshmallows in the dessert bars would not thaw well, resulting in a not-so-tasty treat. But, they are so easy to make, you could whip these up in no time when you are craving them or need a quick dessert.

We don’t have double stuff Oreos where I live just regular. I was thinking that I would need to either use a bit more marshmallows or else a big spoon or two of vanilla frosting. What would be your best guess?
After extensive searching and effort here are the results. Recipe as is yields a softer/chewier product falling on the very sweet side. Using regular Oreos yields a dryer/crunchier bar that is both less sweet and more chocolatie. Using regular Oreos and adding 3 generous tablespoons of vanilla frosting (I use homemade) to your melted marshmallows will result in bars closer to the texture and flavour of the original, but a bit more chocolate and a bit sweeter still. Finally, using regular Oreos but using an extra cup of marshmallows yields a soft/chewy more chocolatie but less sweet bar. I had no issues with freezing any of them, but don’t recommend eating them frozen.
These bars are so delicious. I made them for my son’s homecoming dinner and the teenagers ate them up! Some of the parents may have snuck some too 😉
I just made these and they are in the refrigerator. I am taking to a friend tomorrow, so don’t know how they will taste. I wanted to comment that this recipe must be pre-Covid inflation because both the mini marshmallow bag and the Oreo bag were under the ounces measurement you sited. I didn’t stress as the reduction seemed proportional. Just wanted you to know, in case the manufacturers continue to reduce their standards.
Thank you for letting me know that, Mary! I will be sure to double check when sharing new posts.
I really wanted to make these, but since the measurements aren’t ones that are used in 90% of the world, I am unable. It wouldn’t hurt to put measurements in metric for the 7.5 billion people who don’t live in the States.
I literally have OUNCES in the post, which by your criteria, would include everyone in the world. Please feel free to read.
Delicious!! Thanks so much…I have been making these squares for many years but don’t have the recipe memorized so I always have to google it.
As far as measurements go I just wanted to reiterate to all that there really is no wrong way to make them. In Canada the packages are all different sizes…use your friend google to translate from imperial to metric, no biggie. I always use regular Oreos…had to guess at how much because our package is 24 oz. I always use large marshmallows…40 if you want less chewy..I always use 50 and they are nice and gooey.
Yummy 🙂
