Ingredients
Cereal marshmallow bars are a quick and easy no bake treat that everyone enjoys! Customize it with your favorite breakfast cereal. Marshmallows pair well with Cinnamon Toast Crunch, Kix, Cherrios, and Apple Jacks.
There are three components to this recipe:
- butter
- marshmallows
- cereal
Recipe can be made with salted butter. Simply omit the additional salt in the recipe. I recommend mini marshmallows instead of the larger varieties.
Throughout the year Lucky Charms releases limited edition specials. For example, the Saint Patrick’s Day packaging only contains green and gold marshmallows! For extra colorful crunch, you can add in some Lucky Charms “just magical marshmallows.“
