What You’ll Need
Here are the 3 ingredients needed to make this easy no bake dessert. See the recipe card located at the bottom of the post for full details and instructions.
- Oreo Cookies– You can use the regular Oreos or Double Stuf or even Mega if you like.
- Marshmallows– I used the full size large marshmallows for this recipe. Find marshmallows in the baking section of the grocery store. I’ve also made this recipe using mini marshmallows. You’ll use 7 cups of mini marshmallows and 6 tablespoons of butter if using mini.
- Butter– I generally use salted butter for my recipes, unsalted works just fine too.
How To Make No Bake Cookies and Cream Bars
Crush Oreos. Place all of the Oreos in a food processor or blender and mix until ground. If you don’t have a food processor, you can use a high powered blender or even put the Oreo Cookies inside a large zipock and use a rolling pin to crush. I’ve used all methods. It’s great if there are some Oreo’s that aren’t fully crushed. Gives some good texture to the bars.
Melt Marshmallows. Melt marshmallows and butter in microwave in a large heat proof bowl until puffed, about 1 1/2- 2 minutes. You can also melt the marshmallows and butter over the stovetop in a large pot if desired. If using a pot over stovetop melt over medium to medium low heat and stir contantly until melted.
Note. If using large marshmallows, you use 5 cups large marshmallows and 4 tablespoons butter. If using mini marshmallows, use 7 cups mini marshmallows and 6 tablespoons butter. You can melt butter and marshmallows in a large heatproof bowl in the microwave for 1 1/2-2 minutes, or over stovetop in a large pot over medium heat stirring until melted.
Combine Cookies and Melted Marshmallows. Working quickly, pour the ground cookies into the melted puffed marshmallows. Marshmallows will begin to set up pretty quick.
Transfer Mixture To Pan. Mix quickly and press into an 8×8 inch pan and let cool for 10 minutes. Cut into squares to serve.
Recipe Tips For Success
- Measure Out Ingredients In Advance. Make sure you measure out your ingredients before starting. Once the marshmallow mixture is melted, you need to work quick.
- Use Fresh Marshmallows. Check your mini marshmallows to make sure they’re fresh and soft. Sometimes when they’ve sat in the pantry for too long, they get hard.
- Plastic Knife. Use a plastic knife to cut into squares to prevent sticking. I cut into squares before the treats get to room temperature. Still somewhat soft makes for easier cutting.
- Grease Hands. Use a little softened butter or cooking spray on your hands to press warm treats into pan. Prevents it sticking to your hands.
How To Serve
Serve bars room temperature on a cake stand or individual plates. Use a plastic knife to cut into squares while bars are still semi-soft or use a sharp knife that’s been buttered or sprayed with cooking spray. These cookie bars are so perfect for any dessert party, birthdays, holidays. So easy and everyone really loves them!
Leftovers
Store any leftovers in an airtight container or Ziplock bag for up to 3 days for best tasting results. I don’t recommend freezing or refrigerating these bars.

Hi there, these look absolutely awsome, I mean Oreo’s and marshmallows that must be heaven.
But I have some weight conversion questions. I think I already know how much Oreo’s I am gonna need (about 3 packets with 14 cookies)
But I have no idea how much 5 cups worth of marshmallows is. We don’t have cups here in the Netherlands and when I look at conversion websites they give different weights for different. One website says it is about 40 marshmallows, but I don’t want to be standing in the supermarket trying to count all the marshmallows in the bag :’)
Looks tasty I guess I have to give up the dieting for a day if I want to eat these.
I made these for me and my boyfriend, and we inhaled the entire pan over the weekend. I’ve never eaten so many Oreos in my life. This recipe is genius.
I made these with mint Faux-reos and wrote about them
here. They were yummy but what I couldn’t figure out was why they tasted like they had rice Krispies in them. Very delish, but weird!
looks nice but when i tried to do it, its was a huge mess and it looked nothing like the pictures BUT BUT the taste was AMAZING!! 🙂
Does it matter if you use salted or unsalted butter?
I always use unsalted 🙂
OMG, Yum!!! Thanks 🙂
What a fun, easy recipe! Definitely saving this recipe:-) Take care, Terra
Thanks Terra, hope you enjoy!
these look amazing! roughly how many oreos are in a 16oz pack? they’re sold in different packs here in ireland.
Oh MY, this looks so delicious. Family loves Oreos..
That looks so good… I can’t stand it! I’m going to have to make these as soon as I can get to the store. Thanks!
Hope you enjoy Petula!!
thats reakky awesome i loved it do visit my video recipe blog for more spicy tasty recipes at freshrecipes.blogspot.com
I wonder if I can justify buying a small food processor just for this…
I just tried to make these without using measuremeants, added way too many marshmallows and ended up with something that tasted like chewing gum with cookie stuck in it! Not recommended! Follow the recipe! xx
I can’t wait to try these! Someone made the best oreo cake for me this week, hopefully it’s not an overload. It looks so delish! 🙂
Oh man, I love anything to do with Oreos. We’ll need milk!
Looks deliciousssss!!!!!!!!!! Momma like it!!!! ;D xD jk but I DO like it.
You are genius
Wow this is so simple and looks really delicious! I could totally use some of those right now 🙂
my sister absolutely hates oreos- so i made this with the golden kind. it turned out fabulously and was a huge hit! thank you so much!
I tried making these last night, I need to make them again, but adjust the amount of marshmallow. I measured out 5 cups (measuring marshmallows isn’t as easy as it sounds) and it was too much. The Oreo to marshmallow ratio was off. They taste amazing but there is no way to cut them into bars, they’re too rubbery!
Yummy! I just made these and they are great!
I just made them and they were quick and easy. I think next time I wont ground them so much. Thank you so much for all the great ideas that you post!!!
Made sure to link you in the blog 🙂

Saw your blog post last night–bookmarked it for later. At the grocery store today, I picked up two of the ingredients, thought for sure I remembered just three things in your picture, and knew I had butter at home.
Have sent text message to son, “hands off” the Oreos and Marshmallows, I’m making a surprise!
Can’t wait for tomorrow. Thanks for the post, it’s honey extracting time here and that doesn’t leave time for much else, but this little yummy I can fit in!
Can you use marshmallow cream? I prefer not to use regular marshmallows since it has gelatin. Thanks. These look way too good.
Monica, I am really not sure how the marshmallow creme would work. I would try just a small portion to test it out 🙂
It’s looks soo delicious, I got water in mouth ! mmmmmmmmm!
I replaced the oreos with hershey’s bars 😀 Now I made some S’more Creme Bars topped with some vanilla ice cream for my family 🙂 So many endless possibilities you can make with this recipe.
I know Ariana, there are dozens of fun things you could do with this! Have fun 🙂
Oh my goodness! These look even better than oreo stuffed brownies!! Yum!!
thank you thank you thank you! You just solved my dilemma of what desssert to make for this weekend. I see that you lined the pan with foil, did you grease or spray the foil so it would make it easier to cut out? Can’t wait to give these a try – will need to make a double or triple batch!
Jess
i like cake and pastries but doctor says ‘no’all of its
These look delicious! I plan on making them for my fiance as a graduation present from Army Basic! After months of Army food I’m sure he’ll LOVE these!! 🙂
Baby Baby you know my life
Charls.
such a fantastic idea! especially for someone like me who is great with cooking but when it comes to baking its kind of a gamble! I’m working on getting better with the measuring and lack of ADD baking requires, but this is a great way for me to impress my friends without stressing over getting it right!
the perfect recipe for my sweet-lover husband and 2 year old daughter as my oven just broke down! thanks for sharing!
wow! those photos just told me: pull yourself away from the screen right now — go to the kitchen — grab whatever sweet you might find there
Hope you enjoy!!
I’m pretty sure Oreos are made with Partially Hydrogenated Oils, which always contain trans fats. Even if the packaging says 0 grams Trans Fat. This is because an FDA ruling decided that if it has less than 1 full gram of trans fat per serving, that’s the same as zero. Despite the fact that the human body has no way of passing trans fats and the only way to get rid of them is with fat reduction surgery!
… other than that, your recipe sounds delicious.
