Lucky Charms Marshmallow Treats Recipe

A cute and unique St. Patrick’s Day snack can be fun for the kids to help make as well as eat. Kids love cereal so we pretty well always have a couple of boxes on hand for breakfast or to make no-bake cereal bars

A variation of these Lucky Charms Marshmallow Treats is one of the first snack recipes that I made with my son.  We practiced measuring cereal and as he got older he learned to stir the marshmallows and cereal together.  We really enjoy doing quick activities like this together.

As a mom with young kids it’s fun to celebrate holidays – big and small.  Here is an easy recipe that our family makes for fun and easy St. Patrick’s Day snack.

It doesn’t really matter what kind of cereal you use. These Reese’s Puffs Cereal Bars are another favorite. As long as the cereal sounds good with melted marshmallows do an experiment and give it a try!

How to Make Lucky Charms Cereal Bars

Lucky Charms Cereal Bars are super simple to make. I actually have this recipe memorized and I can’t seem to remember much of anything anymore. So that means the recipe is EASY!

In a large pot melt 4 tablespoons of butter or margarine over medium-low heat. Then stir in 8 ounces of mini marshmallows until they are melted.

Remove the melted marshmallows from the heat and stir in 6 cups of Lucky Charms cereal. Stir well and then spread into a lightly greased 9 x 13″ pan.

If you really like the cute marshmallows in the cereal you (or your kiddo) can pick some extra marshmallows out of the remaining cereal and sprinkle on top.  I like to wet my fingers to make it easiest to smooth the mixture out.  Cut into pieces of your desired size and enjoy.
