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.

These look so good, and easy! Do they freeze well?
How long do these stay good for? Thanks!
This is so easy to make and very addicting. So good. Thanks for sharing .
I made these with half oreos half rice crispys and did it on a stove and not the microwave (don’t like the microwave.) After that I cut them into 1 inch squares and dipped them into melted chocolate. They made a great sugar tooth cure for all my friends.
Could you add in like white chocolate chips or nuts
Is this just one bag of large marshmallows?
My thought exactly. How do you measure the marshmallows…loosely or pressed tightly?
Loosely in the measuring cup.
Can you freeze this ?
Can you freeze these?
