Ingredients You’ll Need
What’s amazing about this Oreo Rice Krispie Treats Recipe is how just a few simple ingredients come together to create such a memorable snack. Each component plays a crucial role — from the fluffy marshmallows binding it all together to the Oreos adding that signature twist.
- Mini marshmallows (9 cups, divided): These fluffy little gems provide the gooey binding agent and give each bite that perfect chewy texture.
- Krispie cereal (5 cups): The classic crunchy base that adds that iconic snap and the light, airy feel you love in rice krispie treats.
- Oreo cookies (16, chopped): Crushed into chunks for pockets of chocolate and cream flavor — they make this treat unforgettable.
- Butter (5 tablespoons): Melts everything smoothly and adds a rich, silky flavor that complements the sweetness.
- Salt (1/2 teaspoon): Just a pinch to balance the sweetness and enhance all the other flavors.
How to Make Oreo Rice Krispie Treats Recipe
Step 1: Prepare Your Pan
Start by generously coating a 9-inch square pan for thick treats or a 9×13-inch pan for thinner bars with butter. This simple step not only prevents sticking but also adds a subtle buttery flavor to the edges, making your treats extra tasty.
Step 2: Mix Dry Ingredients
In a large bowl, combine the Rice Krispies cereal, chopped Oreo cookies, and 1 cup of mini marshmallows. Mixing these dry ingredients before adding melted marshmallows helps distribute the Oreos evenly throughout each bite, so you don’t miss a single chunk of cookie.
Step 3: Melt Butter and Marshmallows
Using a large pot over medium heat, melt the butter slowly. Stir in the salt and then add the remaining 8 cups of marshmallows. Keep stirring constantly until the marshmallows are completely melted into a smooth, golden mixture — patience here will ensure your treats bind perfectly without burning.
Step 4: Combine Wet and Dry Mixtures
Pour the gooey marshmallow mixture over the bowl of Krispies, Oreo cookies, and marshmallows. Gently fold everything together, making sure each crisp and cookie piece gets coated with that shiny, sticky marshmallow goodness for deliciously cohesive treats.
Step 5: Press into Pan
Transfer the mixture to your prepared pan and press down gently but firmly with a spatula or buttered hands. Don’t press too hard or the treats will turn dense, but make sure they’re packed enough to stick together nicely when cut.
Step 6: Cool and Slice
Allow your Oreo Rice Krispie Treats to cool at room temperature for about 30 minutes. This waiting time is key so they can set properly for clean slices. Once firm, cut into 12 generous squares, ready for sharing or enjoying all to yourself!
How to Serve Oreo Rice Krispie Treats Recipe

Garnishes
For a dazzling presentation, consider sprinkling a few crushed Oreos or mini chocolate chips on top just after pressing the mixture into the pan. Drizzling some melted white or dark chocolate over the cooled treats takes them from tasty to show-stopping.
Side Dishes
These treats shine as a standalone snack but pairing them with a cold glass of milk or a scoop of vanilla ice cream turns them into a delightful dessert experience. If you’re hosting, fresh berries or fruit salad offer a refreshing contrast to the richness.
Creative Ways to Present
Want to add a playful twist? Try layering the mixture in clear jars or cups for Oreo Rice Krispie treats parfaits. Or use cookie cutters to shape them into fun designs for birthdays or holiday celebrations — kids and adults alike will be enchanted.
Make Ahead and Storage
Storing Leftovers
Oreo Rice Krispie Treats stay fresh best when stored in an airtight container at room temperature. Keep them away from direct sunlight or heat to maintain their soft yet crunchy texture for up to 3 days.
Freezing
If you want to stash these treats for longer, wrap individual squares tightly in plastic wrap and place them in a freezer-safe container. Frozen treats can last up to 6 weeks without losing their iconic flavor or texture.
Reheating
When ready to enjoy frozen treats, let them thaw at room temperature for about 30 minutes. If you want a warm, melty bite, pop them in the microwave for 10-15 seconds — just enough to soften the marshmallow without melting it completely.
FAQs
Can I substitute regular marshmallows for mini marshmallows?
Absolutely! Regular marshmallows work just as well; just chop them into smaller pieces to help them melt evenly and mix better with the cereal and Oreos.
Is it necessary to use salted butter?
No, but using unsalted butter and adding the 1/2 teaspoon of salt allows you to control the saltiness exactly, balancing sweetness without overpowering the treat.
Can I use another type of cookie instead of Oreos?
Yes! While Oreos add that iconic flavor, feel free to experiment with other sandwich cookies or chocolate chip cookies for a unique twist.
How can I make these treats gluten-free?
Choose a gluten-free crispy rice cereal and gluten-free Oreos or sandwich cookies to make the recipe safe for gluten sensitivities — the texture and flavor remain delightful.
What’s the best way to cut the treats without crumbling?
Use a sharp knife and clean it between cuts to prevent sticking and crumbling. Press down firmly but gently to maintain the treat’s shape.
