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.

    Oreo’s are my husband’s all time favorite dessert. I think I might make these for a valentines day treat to surprise him!

  2. Janette

    I made these and they were a huge hit! I would use a little less marshmallow next time I think but other then that, super good and super easy! Thanks for sharing!

  3. Lauren

    i made two batches of these. My first batch I guess I must have pulsed it a little too fine and it didn’t come out looking anything like yours. I am going to call it “Christmas coal” because that is exactly what it looks like. Second batch I hit the Oreos in a bag with a meat mallet and it was a better consistency. But still don’t look as gorgeous as yours.

  4. Jackie

    I am making these right now and it is not turning out like it says. It is sticking to the foil and is not firming up. I have them in the freezer right now hoping it will help. It does taste delicious thought.

  5. Christa

    These are awesome.. I made these using a small cookie scoop to make them bite size for a work party. Everyone loved them..

  6. Taylor

    How long do these usually last?
    Making them for a friend who won’t be here for a couple of days and I want to know if they will still taste okay
    🙂

  7. Camila

    Hello! Ive made these twice already and they are very yummy, but they don’t mold to the pan at all; I have to push down the mixture myself so that it somewhat molds to the pan! Also, they are almost impossible to cut so I can’t get those perfect squares that you do! Is this supposed to happen or am i doing something wrong? thank you very much 🙂

  8. Drew

    These are super delicious! I have made them before 🙂 However, I was wondering if this recipe is diabetic friendly?

    These look delicious!!! Two questions-have you ever tried using Marshmallow fluff instead? How far in advance can these be made & how do you recommend storing them?

    Thanks!

  11. Indra Wouters

    hey, I divided the recipe by 4
    but the proportions were still the same
    But… my cookies are not chewy at all,
    And it has become a brown gunk 🙁
    Too bad …bah 🙁

  12. steve

    Just wanted to let you know that my daughter used this recipe for her cooking project at the county fair. The judge loved the bars and awarded a purple ribbon for them. Overall my daughter got reserve grand champion in her class, thanks to these treats. She cited your blog as the source on the recipe card. Thanks for such a great treat.

  13. Nikki

    Ok so they look so so good. But I followed the directions and it was a fail! It turned out to be one big blob! I could not even get the treats off the foil. Not sure what went wrong but I followed all the directions and it just didn’t work out like yours… They look delicious though…

      1. Chezka Velaso

        thank you 🙂 but what should I do if it gets too sticky? how can I prevent it from to much sticking with the foil?

  14. Andria

    My daughter and I made these tonight and they came out watery…and won’t thicken…did I leave the marshmellows in too long? I did 2 mins… 🙁

  15. Brittany Brouwer

    I’m going to make these for the superbowl!!! Only ? I have is, how do you transfer the gooey mess from the bowl to the pan? Is there an easy way since i’m sure it is sticky?

  16. anne

    Made these and it was a hit! though im having problems because it keeps sticking on the foil and doesnt look presentable after picking out the tiny foil left on each piece.. any suggestions how to prevent this?

    Thanks!!
