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!

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

1. Grease a 9×13-inch baking pan with butter and set aside.
2. Combine the cereal, crushed cookies, and sprinkles in a large bowl.
3. In a saucepan set over low heat, melt butter. 
4. 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.
5. Transfer the mixture to the prepared baking pan and gently press down, creating an even layer. 
6. Allow the treats to cool completely, for about 1 hour, before cutting into 12-16 squares.
