A super fun no-bake cereal bar made with Lucky Charms, sprinkles, birthday cake Oreos, and white chocolate chips

Lucky Charms just got a birthday party makeover, Rainbow Sprinkle-style! These no-bake cereal bars combine gooey marshmallows, crunchy birthday cake Oreos, and sweet white chocolate chips for a treat that’s colorful, chewy, and ridiculously fun. They’re great for parties, school events, or whenever you need a fun, colorful treat.

Recipe Rundown

You have no idea how excited I was when I spotted this rainbow sprinkle version of Lucky Charms. Every cereal piece is speckled with colorful sprinkles, and the whole box is birthday cake flavored. Yes, you can totally make them like classic cereal bars—but I had to toss in a few mix-ins. I added chopped Oreos, white chocolate chips, and a handful of extra sprinkles. Customize them however you want—drizzle them with white chocolate, add colored melts, or swap in your favorite cookie pieces.

FAQ

Can I use regular Lucky Charms instead of Rainbow Sprinkles version?
Yes! The Rainbow Sprinkles version just adds extra color and fun, but any Lucky Charms cereal will work.

What’s the best way to cut these cleanly?
Let them cool completely, then spray a sharp knife with nonstick spray or wipe it with a bit of oil before cutting.

Can I leave out the Oreos or substitute something else?
Totally! Try confetti cookies, chopped animal crackers, or even crushed birthday cake-flavored granola bars.

Do the white chocolate chips melt in the mix?
They soften slightly but should hold their shape if you add them at the end and don’t overmix.

Sprinkle of Fun

Stack these bars high on a cake stand and turn them into a no-bake centerpiece for your next dessert table. They’re colorful, crowd-friendly, and don’t need refrigeration—plus, if you’re traveling for a birthday party, they’re way easier to bring along than a cake.
