These Lucky Charms Cereal Bars are a fun, sweet twist on the traditional Rice Krispie treat. They'd be perfect for St. Patrick's Day!

Lucky Charms Marshmallow Bars | A Nerd Cooks

I cannot be trusted around cereal

I love cereal. Like, to an unhealthy, almost unnatural degree. It really doesn't matter what kind of cereal, either. Super sugary children's cereals? Yes, please. Healthier options? Also yes. I'm not exactly sure what it is that I love so much, but I can't help myself. We don't keep in the house for this reason.

An exception was made for these bars. Lucky Charms (for which I have a particular affinity) replace puffed rice cereal in a traditional Rice Krispie Treat recipe to make Lucky Charms Marshmallow Bars. These were perfect for St. Patrick's Day, and seriously couldn't be easier to make.

What ingredients go into these cereal bars?

Butter: I use unsalted butter.
Marshmallows: I've found that the mini marshmallows are easier to work with than the full-sized guys. But use whatever you have on hand!
Lucky Charms cereal: The one and only.

How do these bars come together?

If you've made Rice Krispie treats, you know how this process goes.

Start by melting the butter and marshmallows in a big pot. Things will be quite sticky. Pour the cereal into the butter/marshmallow goodness and stir until the cereal has been coated.

Spread everything into a prepared pan, smooth it out, and let things cool down and solidify (if you can wait, that is!).

Want other fun St. Patricks Day recipes?

As it turns out, I have plenty for you!

Try this Chocolate Guinness Cheesecake on for size. It has a chocolate and whiskey ganache, too! I have a Chocolate Stout Bundt Cake, complete with Irish Cream glaze, as well.

Oooh AND, please don't forget about these Mini Baileys Cheesecakes! There's Irish Cream in the cheesecake batter and the ganache. So good.

And if you'd rather drink your St. Paddy's Day treat, give my Baileys Iced Coffee a shot (pun intended).
