While Lucky Charm Treats are the ultimate snack or dessert all year, they’re especially fun and festive to serve for St. Patrick’s Day! You can serve them in bar form or cut them into shamrocks, gold pots, rainbows and more!

They’re completely amazing as-is or you can dip them in white or green chocolate! These treats are gluten-free and dairy-free making them suitable for a crowd!

Just like rice krispy treats, they come together quickly and easily! It takes less than 10 minutes to whip up a delicious batch. Even better, you don’t have to wait because they’re no-bake!

Ingredients to Make Lucky Charms Bars

  • Butter – Salted or unsalted. If you are using unsalted butter, I recommend adding ¼ teaspoon salt to the marshmallow mixture.
  • Marshmallows – Miniature marshmallows melt beautifully, but you can use large marshmallows as well.
  • Lucky Charms – The classic coral serves as the foundation and its colorful marshmallows make it fun and festive!


Add Chocolate – Dip half of each treat or fill the bottom of the baking dish with white or green colored chocolate. This makes them like the store-bought Lucky Charms Bars!

Add Sprinkles – Make them even more festive by adding sprinkles! Sprinkle on top just after pressing or fold in.

Cut into Shapes – Use your favorite cookie cutters to cut them into shapes. Butter or spray with non-stick spray and press.

How to Make Lucky Charms Treats

  1. Prep – Grease or butter 9×9 baking dish.
  2. Make Marshmallow Mixture – In a large saucepan, melt butter. Stir frequently until smooth, watching carefully.
  3. Fold in Cereal – Quickly and carefully fold in cereal.
  4. Press – Press mixture into baking dish. Butter the back of a large spoon or your hands and press to smooth. I like to leave mine a bit loose for softer, chewier treats, but you can really pack them in, too for maximum crunch! lucky charms bars pressed into gold pan
