Do you love Rice Krispies treat bars and Lucky Charms cereal? Then this recipe is for you. It’s a perfectly festive way to celebrate St. Patrick’s day without breaking out any green food coloring. Plus, it only requires three ingredients (and two optional, but highly recommended, ones). These bars have a double dose of marshmallows, thanks to the Lucky Charms, and are an amazingly tasty upgrade to the classic marshmallow and cereal bar.

You can make Lucky Charms marshmallow bites by swapping the cereal called for in your favorite Rice Krispie treat recipe, but take my advice here and spend a few minutes pulling out a cup of the Lucky Charms marshmallows for topping the bars.

Or, if you don’t have that kind of time, just order cereal marshmallows in bulk from Amazon! (Isn’t the internet wonderful?)

Buy them: Charms Original Cereal Marshmallows, $11.99 for 2 pounds

Most cereal bars are just butter, marshmallows, and cereal, but you can take these treats to the next level by adding a dose of vanilla and salt to the mix too.
