Oreo Rice Krispie Treats
While there’s nothing quite like a classic Rice Krispie Treat, I adults and kids alike can all agree that adding Oreos to a dessert is never a bad idea. In this case, it’s an excellent idea that only requires extra marshmallows and crushed Oreo cookies. These cookies and cream Rice Krispies are thick, gooey, and stuffed with chopped Oreo cookies.

Just to be sure they weren’t even remotely dry, this recipe includes extra marshmallows. In about 30 minutes flat, you can have yourself a fun no-bake treat for a fun snack at home, school party, or potluck.
Key Ingredients
- Salted Butter – I use salted butter for all of my Rice Krispies treats recipes because they really do benefit from that little extra salt. If you use unsalted butter, just add an extra pinch to the butter as it melts.
- Mini Marshmallows – mini marshmallows melt much faster than regular marshmallows so this is a must. If you only have regular marshmallows, you can chop them up first. You will need to save about 2 cups to mix into dry cereal.
- Vanilla Extract – don’t skip this! It adds so much flavor and balances things out.
- Rice Krispies Cereal – while Rice Krispies are the classic, any kind of puffed rice cereal will work.
- Oreos – make sure to use regular Oreos instead of double-stuffed. They have the perfect cream-to-cookie ratio for this recipe.
How To Make Oreo Rice Krispies
- Melt the butter and marshmallows. In a large pot, melt the butter and then add all but 2 cups of the mini marshmallows. Stir on low heat until almost completely melted and then add the vanilla.
- Add the dry cereal mixture. In a bowl, combine the Rice Krispies, crushed Oreos, and extra marshmallows. Fold this into the melted butter mixture.
- Press into a baking dish . Lightly spray a 9” x 13” baking dish with nonstick spray, then transfer the mixture and press down gently with your hands to create an even layer.
- Cool. Allow to cool for at least 20 minutes in a cool dark place before cutting and serving. Enjoy!
Recipe Variations
- Extra Cookies: Stir in whole mini Oreos for double the crunch.
- Drizzle: Top with melted white chocolate (some sprinkles would be fun too0, or milk chocolate for a bakery-style finish.
- Flavored Cookies: Swap in golden Oreos, peanut butter sandwich cookies, or holiday flavors.
- Spinkles: Add colorful sprinkles for birthdays or celebrations.
- Loaded: Mix in mini chocolate chips, M&Ms, or chopped nuts along with the Oreos.
- Double Chocolate: Use Cocoa Krispies instead of Rice Krispies for a double chocolate Twist.
Frequently Asked Questions
As long as they are stored in an airtight container at room temperature, these Oreo Krispie Treats should stay fresh for up to 3 days.
The most common reason for hard and dense Rice Krispie Treats is that the mixture was cooked either too hot or for too long. This cooks the sugar to a higher temperature and evaporates extra moisture, making them hard instead of soft and gooey.
They can also get too dense if you press the mixture too firmly into the pan. You want it to hold together but not be pressed so hard that it feels like a brick!
Because of excess moisture in the fridge, I don’t recommend storing these there. Instead, store in an airtight container at room temperature, making sure they are in a cool and dark place.
Recipe Substitutions
- Use any Oreo Flavor: Golden Oreos, Lemon Oreos, Mint Chocolate Oreos, Birthday Cake Oreos or Red Velvet Oreos, all the flavors work well for this fun treat.
- Add More Mix-Ins: Mini freeze dried marshamallows, M&M’s, Pretzels, chopped nuts, or mini chocolate chips are a delicious addition.
- Make it Holiday Themed: Add sprinkles or change the sprinkle colors for Christmas, Halloween, Valentine’s Day, Easter, 4th of July, or birthdays.
Tips for the Best Oreo Rice Krispies
- Use fresh marshmallows: Older marshmallows don’t melt as smoothly and can make treats hard.
- Use salted butter for a great sweet, salty flavor. Or you could add just a little pinch of salt if you don’t have salted butter on hand.
- Don’t over-stir: Mix just until combined for the softest, chewiest bars.
- Use a knife to roughly chop the oreos. You could also put the oreo cookies in a ziplock bag and crush them with a rolling pin. Just don’t use a food processor or the oreos will be ground too finly and you won’t get that fun chunky oreo texture that makes this so fun to eat.
- Coat everything with butter: Butter your pan, spoon and even your hands to prevent sticking.
- Press gently: Pack into the pan just enough to hold shape-don’t smash too hard.
- Cool before cutting: Let set at room temperature and chill for clean, even slices.
Storing and Reheating
Room Temperature: Store your Rice Krispies Treats in even layers separated by wax paper in an airtight container at room temperature for up to 3 days
