I love fun St. Patrick’s Day recipes like these marshmallow cereal bars!

I remember my sister always trying to pick out just the marshmallows and leaving the cereal. These bars get around that while still being delicious and fun!

I was not much of a cereal person but always loved the colors of these marshmallows. I wish they had the unicorn ones when I was little!

Cereal Bar Ingredients

This Lucky Charms Cereal Bar is flexible for what you have on hand or prefer!

I love to use yogurt chips mixed in with the cereal. You could also use white chocolate chips, but then it turns into more of a dessert bar.

Alternatively, you can skip the chips and just add more cereal.

Peanut butter can be replaced with any favorite nut butter, like almond butter.

And I like maple syrup, especially since it uses a good amount of it in this recipe, but you could also swap it for honey, agave, or any other sticky syrup.

What are Cereal Bars?

Cereal bars are somewhat new to me that I learned about rather recently.

They are made primarily with cereal and mixed with things like nut butters, honey, and maple syrup to get them sticky enough to form into bars.

These are made with Lucky Charms Cereal which make them fun for St. Patrick’s Day as a snack, dessert, or easy breakfast.

I love how the marshmallows bring pops of color and fun marshmallow shapes to the bars!

And since Lucky Charms are gluten free, so are these treat bars!

Storing the Cereal Bars

You can keep these cereal bars in an airtight container for up to a week.

They might be a little sticky, so if desired you can wrap each in parchment paper. Or just put paper between stacked layers.

The cereal bars are best when still soft!

You could use any nut butter in place of peanut butter.
Yogurt chips are a fun addition to these bars. White chocolate chips also work, although much sweeter, or the 1/2 cup can be replaced with additional cereal instead.
