Oreo Rice Krispie Treats
While there’s nothing quite like a classic Rice Krispie Treat, I think we 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 saucepan, melt the butter and then add all but 2 cups of the mini marshmallows. Stir 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.
- Cool. Allow to cool for at least 20 minutes in a cool dark place before cutting and serving. Enjoy!
Recipe Tips and Variations
- If you like your Rice Krispie Treats thick and gooey, make them in a 9” x 9” pan instead!
- Do not be tempted to try and cut them too early or they will fall apart. Make sure that they have a chance to cool completely.
- Try drizzling with melted chocolate, or adding mini white chocolate chips into the dry cereal mixture.
- Experiment with different Oreo flavors like Golden Oreos, peanut butter, and mint.
- For a double chocolate twist, use Cocoa Krispies instead of Rice Krispies.
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.
Storage Instructions
- 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
