St. Patrick’s Treat: Lucky Charms Bars

Lucky Charms Treat

St. Patrick’s Day + love of baking = Tasty Treat

Let the St. Patrick’s Day baking commence! While one of my all-time favorite holidays is a week away, I couldn’t help but get in the mood with a little treat since my kiddos is having friends over tonight. Trust me, there will be more nom-noms to come, but this is a little warm-up. It’s fast, easy, and cheap.

Fast because it takes less than ten minutes to prep these nom-noms.

Easy because there are only three ingredients, a pot, a spatula, and a 9 X 13 pan involved.

Cheap because I bought everything I needed for less than $5 – the marshmallows cost a dollar, the cereal was on sale for two dollars, and the amount of butter used probably worked out to a dollar or so as well.



Lucky Charms and Marshmallows!


Oh, and they are delicious. This is my go-to treat (see variations below) when I want to please a crowd of kids, tweens, or teens. You can’t beat this marshmallow and cereal bars.

Start with this:

Melt butter in large pot

Add the marshmallows and stir until they melt down:

This looks good!

Next, add your Lucky Charms and mix well:


Pour your mix into a prepared (we like to use butter) 9X13 pan:

Packed in and looking scrumptious!

Make sure you pack it in so it will be easier to cut into bars. We let it sit for an hour or so at room temperature before trying to cut it….believe me, the kids have a tough time waiting but it is well worth it!

Finished Treat

Cut into squares and served in the pan or on a platter, it doesn’t seem to matter. These delicious bars won’t last long!


As I mentioned before, we’ve done a number of variations of this recipe. Most commonly, this treat is made with Rice Krispies but over the years I’ve noticed people adding their own spins on this classic. Please comment with your suggestions if you care to share!

  • Try Fruity Pebbles, Peanut Butter Crunch, Captain Crunch with Crunchberries, Reese’s Puffs, or Trix.
  • Try adding sprinkles, mini morsels, or mini M&Ms when you add the cereal.
  • Use a little food coloring in your marshmallow and butter mix to add color.
