FAQs

Here are a few of the most frequently asked questions when making Lucky Charms cereal bars.

Can you purchase Lucky Charms Marshmallows separately?

Did you know that you can actually just purchase the marshmallows found in Lucky Charms cereal??? I’ve seen them before at specialty candy shops but you can also find them on Amazon! A big old bag of those crunchy sugar-filled dehydrated marshmallows delivered right to your doorstep!

How to store marshmallow treats.

I’ve made a ton of rice krispie treats over the years. I found the best way to store them is in an airtight container or storage bag in the refrigerator. You can store them in the fridge for up to 5-7 days if they actually last that long in your house! The key is an airtight container so that they don’t get stale!

Are lucky charm bars healthy?

Unfortunately, these Lucky Charms Cereal Bars are not healthy as they contained processed sugary cereal mixed with butter and additional marshmallows and topped with melted white chocolate.

Are Lucky Charms cereal bars gluten-free?

Unfortunately, Lucky Charms cereal bars are not gluten-free as they contain whole grain oats, which may contain traces of gluten.

Are Lucky Charms cereal bars suitable for vegetarians/vegans?

Lucky Charms cereal bars contain gelatin, which is an animal-derived ingredient, so they are not suitable for vegetarians/vegans.

Tips & Tricks

lucky charms cereal treats cut into cubes, drizzled with green chocolate, and stacked on napkin.

Here are a few of my favorite tips and tricks when making Lucky Charms cereal bars.

  • White Chocolate Melts – I like to use the White Chocolate Melts that are colored and found at the craft store, Walmart, sometimes Target in the baking area, or even Amazon.
  • Storing – These treats are best stored in an air tight container for up to 3 days. You can store them in the refrigerator or on the counter in a cool location.
