These Funfetti Oreo Rice Krispie Treats will transport you back to your childhood! These homemade Rice Krispie treats are made with chunks of Oreos, rainbow sprinkles, marshmallows, Rice Krispies cereal and butter for an easy kid friendly dessert!
Rice Krispie Treats.
The name alone brings back a rush of memories from my days as a school bus kid.
Nana was the best lunch packer this side of the equator, and I always had very balanced meals to look forward to enjoying when the lunch bell rang – an entrée, fruit, and a delicious snack, sometimes store-bought, most times homemade.
Her crispy rice treats were KILLER, and I think I’ve figured out her recipe for success.
While they’re not going in any cute plastic lunch boxes, they are being enjoyed by a child – the one in my heart!
This page includes step by step instructions, as well as tips and notes. If you’d like to skip all that, feel free to scroll down to the full, printable recipe card at the bottom of the post. There is also a “jump to recipe” button at the top of the page if you’d rather not exercise your scrolling finger!
Guys. If the cereal treats themselves didn’t have you sold on a quick walk back through your school days, surely the sprinkles will.
C’mon. SPRINKLES. They make everything better.
Funfetti was everything back in the day, wasn’t it? At least for me and my friends it was.
If your mom brought funfetti cupcakes to class for your birthday, you were absolutely the most popular kid for at least a solid week. Bonus points for multicolored frosting.
I used to make these babies in the microwave, no lie – I was a Rice Krispie Treats Cereal addict (remember that stuff?! OMG it was heavenly), so I’d pour a bowl of cereal, mix in extra marshmallows, and nuke it all for a minute or so. Smash it down and BAM…
Giant Krispie Treat.
These are a bit different, a bit more refined. As refined as multicolored crispy treats can be, anyway. You can even add in other cereals to amp up the color ratios (Lucky Charms Rice Krispie Treats, anyone?) – just in case sprinkles aren’t your thing.
Ingredients
Homemade Rice Krispie Treats are super easy to make, and require only five simple ingredients.
- Crispy rice cereal
- Mini marshmallows
- Unsalted butter
- Oreos – your favorite kind work here, any flavor!
- Rainbow sprinkles

How to make Oreo Rice Krispie Treats
- Grease a 9×13-inch baking pan with butter and set aside.
- Combine the cereal, crushed cookies, and sprinkles in a large bowl.
- In a saucepan set over low heat, melt butter.
- Add marshmallows and stir with a rubber spatula until marshmallows are completely melted and smooth. Pour melted marshmallow over cereal and stir until everything is completely coated and begins to clump.
- Transfer the mixture to the prepared baking pan and gently press down, creating an even layer.
- Allow the treats to cool completely, for about 1 hour, before cutting into 12-16 squares.
Tips for perfect crispy rice treats every time
- Use fresh, quality ingredients. Fresh marshmallows melt more easily and lend a smooth texture to your treats. Feel free to use leftover rice cereal in these, but make sure it isn’t stale! And use your best, fave butter! With so few ingredients, the quality of what you use is important.
- Mix it up! Everything from the type of rice cereal to your chosen Oreo is customizable in this recipe. Try chocolate rice cereal with golden Oreos for an inverted treat.
- Store them properly. These will stay fresh and soft for about 3 days in an airtight container or larger zipper bag.
