Oreo Rice Krispie Treats
Chewy Oreo rice krispie treats are filled with bits of cookies and cream! These easy treats are a hit with the whole family and are perfect for any special occasion.
Once you get a craving for something, you often can’t get it out of your brain.
I feel like that has been the case with rice krispie treats lately. My last batch of strawberry rice krispie treats didn’t last long, so I had to make another pan soon.
Oreos are some of our favorite cookies, so it was only natural that I’d need to tuck pieces of them into my next batch of chewy marshmallow squares!
These treats only require one extra step from the classic recipe, so they’re ready just as quickly.
Plus, you can use any Oreo flavor you like! Stick with the classic or mix it up depending on your favorites.
Ingredients for Oreo rice krispie treats
You’ll need:
Crispy rice cereal – You can use plain rice cereal, or go for a double chocolate flavor and get the cocoa krispies!
Measure the cereal into a bowl before melting the marshmallow to ensure you have the right amount and can mix them quickly.
Mini marshmallows – I prefer to use mini marshmallows in krispie treats because they melt quicker, and you can use additional unmelted marshmallows for more bits of marshmallow flavor.
Regular marshmallows will work as well, of course!
Butter – Butter helps keep the marshmallow from sticking to the pan as it melts.
Oreo cookies – I recommend using the classic Oreos. You can also swap in Golden Oreos if you don’t like chocolate.
Or, grab one of the special Oreo flavors for a different taste. Try them with whatever seasonal flavor is out!
How to make this recipe
Coat a 9×13-inch baking pan with nonstick spray. For thick krispie treats, you can use a 9×9-inch square pan instead.
Break Oreos into small pieces. You don’t need to use a food processor to chop them; just use your hands to break into the desired size.
Melt the butter over low heat in a large saucepan or pot.
Once the butter is melted, add the marshmallows all at once. Stir to coat with the butter.
Melt, stirring occasionally and scraping any melted marshmallow up from the bottom over the top of the remaining marshmallows.
Once the marshmallows are completely melted and smooth, remove from heat.
Immediately pour in all of the rice cereal and stir until evenly coated. Make sure there are no loose cereal pieces or pockets of marshmallow.
Fold in the Oreo pieces until evenly distributed.
Scoop the mixture into the prepared pan. Grease your hand or a spatula and gently press the mixture into the pan so that it creates an even layer.
You don’t want to press too hard, so don’t worry if the mixture doesn’t reach fully into all the corners of the pan.
Let rest for about 1 hour to cool and firm up before slicing and serving.
Tips for making the best marshmallow treats
Make sure your marshmallows are fresh
Stale marshmallows don’t melt as well and can stick together in the bag. Look for marshmallows that easily separate from each other and bounce back quickly from a gently squish.
Turn the heat down
It can take a while to melt marshmallows, but resist the temptation to make it go quicker by raising the heat on the stove.
This can cause the marshmallows to melt too quickly, burning them before they are fully melted. Burnt marshmallow might be great for s’mores, but it won’t mix well into the cereal.
Work quickly
You don’t want the krispie treats to harden before they are fully mixed, so work quickly to mix together the cereal and marshmallow.
Use a sturdy silicone spatula to help you stir and unstick any bits from the sides.
Storage tips
Oreo rice krispie treats will keep in an airtight container, or wrapped tightly in plastic, for about 5 days, though they will be best within the first 2 days.
Too much air exposure over time can dry them out quicker, so make sure to re-cover the treats each time you grab one!
Rice krispie treats can be frozen, individually wrapped very well in plastic and tucked into a freezer bag, for 3 months. Thaw at room temperature.
