Oreo Rice Krispie Treats combine gooey marshmallow bars with crunchy Oreo cookie pieces for an easy no-bake dessert everyone loves.
Oreo Rice Krispie Treats take the classic no-bake treat everyone grew up on and load it up with chunks of Oreo cookies. You get all that gooey, buttery marshmallow flavor you already love, plus crunchy bites of chocolate sandwich cookie in every square. They come together in one bowl in about 10 minutes, and there is zero baking involved.
If you already make my classic Rice Krispie Treats, this is basically the same easy method with one delicious addition. It’s the kind of recipe you can whip up when guests are already on their way over, and it never lasts long on the counter.
Erin’s Notes
- No Bake: Everything comes together on the stovetop or in the microwave, so you never have to turn on the oven.
- Quick: From start to finish, these are ready in about 10 minutes, plus a little time to set up.
- 5 Simple Ingredients: Marshmallows, butter, vanilla, cereal, and Oreos. That’s it.
- Crowd Pleaser: Kids and adults both go for these at parties, potlucks, and lunchboxes.
Ingredients You’ll Need
- Marshmallows: Use fresh marshmallows. Marshmallows that have been open for a while dry out and won’t melt as smoothly.
- Butter: Cutting the butter into cubes before microwaving helps it melt evenly along with the marshmallows.
- Vanilla Extract: Don’t skip it. It rounds out the sweetness of the marshmallow mixture.
- Rice Krispies: Regular Rice Krispies cereal, or any crisp rice cereal you have on hand.
- Oreo Cookies: Coarsely chop them so you end up with good-sized chunks of cookie and cream throughout, not fine crumbs.
How To Make Oreo Rice Krispie Treats
- Prep the pan. Spray a 13×9 inch pan with non-stick spray and set it aside.
- Melt the marshmallows and butter. Add the marshmallows and cubed butter to a large microwave-safe bowl. Heat for 1 minute, then remove and stir well until the butter is fully melted.
- Add the vanilla. Stir in the vanilla extract until combined.
- Mix in the cereal and Oreos. Pour in the Rice Krispies and chopped Oreos. Mix until everything is well coated with the marshmallow mixture.
- Press into the pan. Spread the mixture into the prepared pan. Spray a spatula with non-stick spray, or wet your hands and shake off the excess water, then gently press the mixture into an even layer.
- Let them set. Let the treats set up for a couple of hours before slicing into squares to serve.
Recipe Tips
- Use fresh marshmallows and a fresh box of cereal. Stale ingredients make for stale, dry treats.
- Don’t overheat the marshmallow mixture, or the treats will turn out tough instead of soft and gooey.
- Chop the Oreos coarsely instead of crushing them into crumbs, so you get real pockets of cookie in every bite.
- Spray your spatula or wet your hands before pressing the mixture into the pan. It keeps everything from sticking.
- Press gently, not firmly. Pressing too hard compacts the cereal and makes the treats dense instead of soft.
Variations To Try
- Swap in Golden Oreos, mint Oreos, or peanut butter Oreos for a different flavor twist.
- Drizzle melted white or dark chocolate over the top once the treats have set.
- Fold in a handful of mini marshmallows along with the Oreos for extra gooey pockets throughout.
- Sprinkle a few extra chopped Oreos over the top before the treats set, for a prettier finished look.
Storage
Store the treats in an airtight container at room temperature for up to 3-4 days. They are best the first couple of days, since they will slowly start to dry out the longer they sit. Freezing isn’t recommended, since the texture changes once they thaw and they lose that soft, gooey bite.
Yes. A 13×9 inch pan gives you thinner treats, while a 9×9 inch pan will give you thicker, bakery-style bars. Just know the setting time may vary slightly with a smaller, thicker pan.
Yes, Double Stuf Oreos work fine in this recipe. Chilling them in the freezer for about 15 minutes before chopping makes them easier to cut cleanly.
