Packed with cookies and white chocolate, these Oreo Rice Krispie treats are unlike any other. A wonderful experience in every square, these are one treat you won't want to share.
You haven't lived until you've tried these cookies and cream rice krispie treats! Made with your favorite chocolate cookie and marshmallow goodness in every square, these are treats that the whole family can enjoy.
But the one recipe that the kids keep asking for over and over again is these Oreo Rice Krispie bars, and can you blame them? They're sooo good! And compared to baked goods, these are pretty easy to make too.
🍯 Why This Recipe Works
- They're easy to make. While there is an extra step or two to make these bars, they are totally worth it. These are even easier to make than Chocolate Peanut Butter Rice Krispie Treats (or at least, that's what I think).
- They're delicious! From the chocolate cookies to the white chocolate, everything about these squares will leave you wanting more.
- Simple ingredients. We don't need much to make this recipe, and the ingredients needed are all simple and basic, making them great for a minimalistic shopping list.
Butter- You can use salted or unsalted butter, depending on what you have on hand, but I like to use salted butter because it enhances the flavors a little better.
Marshmallows- You can use large marshmallows or mini marshmallows to make this recipe. There's not much difference between the two except that large marshmallows can give you a more gooey texture. You could even make Rice Krispie Treats with Marshmallow Fluff.
Cereal- You will need some crispy rice cereal for these treats. In a pinch frosted flakes work fine too.
Oreos- Use name brand or off brand Oreo cookies for this recipe. Chop up some Oreo cookies and sprinkle them on top of the krispie bars for a nicer appearance and stronger chocolate taste.
White chocolate- You will need some white chocolate chips to give us a softer consistency and delicious "cream" flavor to add to our cookies and cream blend. Note that you will need some additional white chocolate for the topping.
For specific ingredients and measurements, please see the recipe card below.
Use differently flavored Oreos! You can make this recipe unique by switching up the cookie flavor. Using green mint Oreos is perfect for St. Patricks Day, but golden Oreos can be a year-round alternative too (add in some rainbow sprinkles, and it's birthday themed!)

🍴 Recipe Tips
Greasing your pan can be done with butter or nonstick cooking spray.
When you press the Krispies into the pan, it really helps to have your hands greased too. This prevents it from sticking. So either rub softened butter on your hands or spray your palms with cooking spray.
Another huge tip is to cook the marshmallows and butter over medium/low heat. The lower the heat the longer it will take, but it prevents overcooking the marshmallows and allows them to turn out perfect and gooey. So this is also very important for avoiding brittle treats later.
Allowing the cereal treats to cool for at least an hour will make it much easier to serve them up and slice. But a good trick to get them out of the pan is to line it with parchment paper so they come out easier and you don't need to slice them in the pan.
You can store these Rice Krispie treats in an airtight container or zipper topped baggie for up to a week or two at room temperature. I recommend eating them sooner rather than later as they'll taste best when fresh.
To freeze your treats, place them in an airtight container or individually wrap serving-sized squares in plastic wrap before placing them in a freezer-safe container. Then freeze for up to 3 months. Thaw at room temperature before eating.
💭 Recipe FAQs
Yes, absolutely! Simply use any margarine instead of butter and follow the recipe as requested. The end result should be a soft texture that tastes fabulous. Another great alternative is to use coconut oil instead of butter, but it will leave a coconut flavor behind.
If you overcook, over-stir, or overheat your marshmallows and butter then you can easily end up with hard cereal treats. I recommend cooking at a low to medium temperature. Slow might take longer, but it won't overheat, and stirring every once in a while keeps you from overworking the sugars too.
No, you do not need to (nor do I recommend) refrigerating your rice krispie treats. While you can place them in the fridge, they will become hard to bite into once chilled. Placing them in the fridge won't extend their shelf life too much either (maybe just a day or so).
