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.

Question: How do you melt the marshmallows? Does the warm butter take care of it? I heard the microwave does crazy things to a marshmallow so I don’t want to go that route. Thanks! Can’t wait to try this recipe!
In times when everybody is worried about teaching kids how to eat well and trying to change bad habits when it comes to food it is quite shocking that there is people capable of giving their kids the worst kind of garbage conceivable. If I believed in a God, I swear I would pray that your kids do not end up morbidly fat and with serious heart diseases.
My husband LOVED these. Thanks for sharing them!
I made these vegan and they were great! I hit up Whole Foods for gelatin free marshmallows (Dandies), earth balance margarine, and oreos are already vegan. Yum!
Mintyy, thanks for sharing! 🙂
These were fantastic! I’m vegan, so I made them with Dandie’s gelatin free marshmallows and subbed Earth Balance margarine for butter. Great!
I made these and you know what? My officemates really thought I baked it. haha and I even got two orders for it. hahaha I said, I’ll just share your recipe in FB coz it is so easy to make 🙂
Haha! Glad it was a success 🙂
I just made these. They taste really good but they didn’t cut into bars. They just stayed one big gooey mess. Not sure what I did wrong??
Just wondering how long these last for??? If I make them now with two weeks until Christmas, will they still be good??
They stick to the bottom of the tin foil! Help
Do you set these in the fridge? I tried to let them set on the counter and they appeared to soft after 10 minutes? Also, are the supposed to be hard like a Rice Krispie or a little soft? Thanks
These are amazing. I don’t know where to being, I’m fifteen and I love to fly airplanes. Thing is I haven’t been flyin for two weeks, also, I was heartbroken last night so obviously today is a bad day, or was, until I found this. I think this might be a holy 15 minutes cure, you are the god of oreos, god bless you.
I have marsmellows and oreos, but not butter :S could I still melt the marsmellows without the butter?
would it still work?
I added Mini Chocolate Chips. Seriously the quickest most delicious snack ever!
Love these so much! So easy and perfect to make now, in the summer. I dread turning on the oven right now so these are just perfect! Thanks for the inspiration!
Oh these looks so delicious. I must admit though I am truly in love with the lovely platter. The ribbon woven through it is delightful and I can imagine many different colors and fabrics that would make any dessert that much more special…
Always a treat to share this site.
Making these at a cook off 🙂 stumbleupon never seases to impress my sweet tooth… Thanks so much 🙂
Oh my goodness! I love recipes with oreos. They are too addicting. I love it!!
You are a cookie cooking genius. You rock!
Thank you Gordon!!
I tried this recipe and it definitely doesn’t work. They don’t take 10 minutes to set… it takes forever. Plus, when you try to pull them off you get pieces of aluminum stuck to the bottoms and sides. It’s nonsense, and I ended up with a gooey mess. DISGUISING.
I savour, lead to I discovered just what I was taking a look for. You’ve ended my four day lengthy hunt! God Bless you man. Have a great day. Bye
Just made these, they are to die for!!
It’s a pity that a whole box of oreos doesn’t make a ton of these wonderful treats… maybe that’s a good thing!
Yumyum! <3
So glad you enjoyed the bars!
Just made these, AWESOME!
Ok….So I thought these looked amazing and my 2 year old loves Oreos. I tried to make them today and it was an Epical Fail lol. Please help…..any ideas as to why they didn’t turn out??
They stuck to the tin foil and when I went to cut them they were just a gooey mess. I ended up having to kinda roll them into balls and flaten them out…..the looked like cow pies, but they taste great 🙂
you ground the cookies together with the cream filling?
Warning: when you make these you WILL try to eat the whole pan yourself. Just wow. So delicious. Can’t wait to try with golden oreos too.
I do agree with all the ideas you’ve offered for your post. They are really convincing and will certainly work. Still, the posts are too short for newbies. Could you please prolong them a bit from subsequent time? Thank you for the post.
Someone brought these to work for Christmas Eve potluck this year, and I could NOT get enough!!!!!! I HAD to have the recipe!!! I Googled “oreos marshmallows” because I knew those were the ONLY ingredients, and THIS came up!!! Am sending the husband to the store as we speak, to get ingredients!!! 1 word….. YUMMY!!!!!!!
Wow! These look amazing!
Awesome. Just made them – like rice crispie treats without the rice! My kids are in your debt.
Question…do you use 5 cups of the marshmallows or 40oz of them? There is a big difference.
Hello! I’m new to this awesome website! I’ve tried this recipe and I was wondering, while I was making them, whether it was alright to separate one layer of oreo mix and place peanut butter in the middle and then place another layer of the mix and let cool. What do you think? (: Will it be too sweet??
I am going to try these with the golden oreos! Great Idea. 🙂
so, I don’t own a microwave. Should I mix it all up, then stick it in the oven for 15 minutes at 375? and stir again? and stick it in again for maybe another 5 just to let it set-up?
I made these before a party. They are absolutely delicious and were devoured almost immediately. I’m definitely going to make them again!
I love Oreo…. i love this recipe..thanks for sharing.
