These Oreo Rice Krispie treats take America’s favorite cookie and mash it up with the classic no-bake treat we all grew up making. You get that familiar marshmallow-cereal chew with chunks of chocolatey Oreo cookies scattered throughout every bite.
What makes these better than plain Rice Krispies treats is obvious – you’re adding Oreos. But what makes them better than just eating Oreos straight from the package is how the cookie pieces get softened by the marshmallow mixture, creating these pockets of creamy chocolate that blend perfectly with the crispy cereal texture.
If you’re thinking this sounds too sweet or worried about the mess factor, hear me out. The cereal balances out the richness of the Oreos, and since everything gets pressed into a pan, there’s less cleanup than making actual cookies. Plus, kids can do most of the work without you worrying about hot ovens or precise measurements.
This is one of those treats that works well for school parties, weekend baking projects, or those moments when you need a quick dessert. Four ingredients, no oven required, minimal dishes to wash, and the kind of crowd-pleasing results that make you look like you planned even when you definitely didn’t.
I’ll show you the simple steps to make this fun dessert, along with all my tips and tricks for getting that perfect chewy texture. It’s like having two favorite desserts in one, and they’re just as easy to make as traditional Rice Krispies treats.

- Marshmallows
- Oreos
How to Make Oreo Rice Krispie Treats
- Break the Oreo cookies into bite-sized pieces. Coat an 8 x 8-inch baking dish with non-stick spray.
- Melt the butter in a large microwave-safe bowl. Do this in 15-20 second bursts, stirring between each interval.
- Once your butter is completely melted, add the mini marshmallows and stir. Then put the bowl back in the microwave for 25-30 seconds. When you take it out, stir until you have a smooth, creamy mixture. The marshmallows should be completely melted and combined with the butter.
- Alternate adding your Rice Krispies and Oreo pieces, stirring with a silicone spatula between additions. This method helps ensure everything gets evenly distributed. Keep stirring until all ingredients are well combined.
- Use your spatula to spread the mixture evenly into the baking dish, pressing gently to fill the corners.
- Cover your dish and let the treats cool for about 25-30 minutes. Once they’re set, cut them into squares and watch them disappear!
Serving Ideas
These Oreo Rice Krispie Treats are absolutely perfect, just cut into squares and served on their own. Add a cold glass of milk for the ultimate cookies-and-milk experience. Of course, they are also a big hit if you wrap them in plastic wrap and add them to a school lunch box.
How to Store
These Rice Krispies treats rarely last long enough in my house to worry about storage! But when we do have leftovers (usually when I make a double batch), proper storage is key to maintaining the texture.
Keep them in an airtight container at room temperature. They’ll stay fresh for 3-4 days, though they’re usually best within the first two days. Don’t store them in the refrigerator.
If they do get a bit firm after a couple of days, pop them in the microwave for 5-10 seconds to soften them up.
Tips & Tricks
Be sure to check out the step by step instructions
- Always use fresh marshmallows and Rice Krispies for the best texture. If your marshmallows have been sitting in the back of the pantry since your July 4th campfire, you need to buy fresh ones!
- Spray your spatula with non-stick cooking spray before mixing. This simple step makes stirring so much easier and prevents the marshmallow mixture from sticking.
- Work quickly once your marshmallows are melted, as the mixture will start to set up quickly.
- While I prefer mini marshmallows because they melt more evenly, regular marshmallows work just as well. Just cut them into smaller pieces first for easier melting.
- Any flavor of Oreo works great. My kids love it when I use the seasonal varieties. The mint ones are especially popular during the holidays!
