St. Patrick’s Day can be such a fun holiday for kids. I’ve heard of many different activities and traditions that people do with their kids to have fun on St. Patrick’s Day.

When I used to teach first grade many years ago, a little “leprechaun” would sneak into our classroom during recess and wreak havoc with the chairs and desks. At my friend’s house, a leprechaun always turns their milk green! Naughty little leprechauns!

One tradition that my family has is to eat Lucky Charms for breakfast on St. Patrick’s Day. I thought it would be kind of fun to mix things up this year and turn our Lucky Charms breakfast into Leprechaun Cereal Treats! My kids loved that they got to eat a dessert for breakfast.

These Leprechaun Rice Krispie Treats are best served the same day, but may be covered and served a day or two after. You can also individually wrap each Leprechaun Treat square and place them into the freezer.
