After experimenting with Fruity Pebbles Treats, it was only a matter of time before I turned my second favorite kid cereal into a tasty marshmallow bar.
St. Patrick’s Day felt like the perfect time to make these Lucky Charms Krispie Treats. With rainbows, leprechaun hats, and pots of gold, it doesn’t get more on theme than this! But of course, we find these buttery marshmallow treats irresistible any time of year.
Lucky Charms Kripsie Treats are:
- No bake– All the work is done right on the stove top! No need to turn on the oven.
- Made with just 5 simple ingredients, including my secret ingredient for super soft rice krispie treats that stay soft for daaaaays.
- Ready in 10 minutes! I mean, how often can you say that for a dessert??
- A kid favorite! My kids go absolutely bonkers for these ooey gooey bars. They look so festive and are perfect for classroom treats and parties.
Key Ingredients
Lucky Charms Bars can be as easy as combining Lucky Charms, butter, and marshmallows, but a few extra ingredients make these the absolute BEST Lucky Charms Krispie Treats.
Here’s what you’ll need:
- Butter– Salted or unsalted both work. I add salt if I use unsalted butter.
- Sweetened condensed milk– This is the KEY to incredibly soft and gooey cereal treats!
- Kosher salt- A pinch of salt balances the flavors and actually brings out the sweetness of the marshmallows.
- Vanilla– Just a splash adds that extra bit of flavor that sets these treats apart.
- Mini marshmallows– You can use regular marshmallows if that’s what you have on hand, but we find the mini kind melts best.
- Lucky Charms cereal- Of course, you’ll need a box of Lucky Charms cereal to make these. Bonus: Did you know Lucky Charms are gluten free? You can serve this treat to your gluten intolerant friends!
How to Make Lucky Charms Krispie Treats
Step 1: Melt butter and condensed milk. Melt the butter in a large pot on the stove over medium heat.
Step 2: Stir in the condensed milk and cook until just starting to bubble, 1-2 minutes.
Step 3: Stir in salt, vanilla, and marshmallows. Add the salt and vanilla extract, then stir in 6 cups of marshmallows. Reduce the heat to low and cook, stirring often, until the marshmallows are just melted.
Step 4: Add cereal. Remove from heat, then stir in the cereal along with the last cup of marshmallows. Stir gently until well coated. Transfer to a greased pan and cool before cutting.
Tip: Reserve a few of the Lucky Charms marshmallows before adding them to the pot, then gently spread them on top of the finished bars for a festive appearance. Buy a bag of Lucky Charms marshmallows here. You can also sprinkle the top with rainbow sprinkles, like these, to make them a little fancier.
How to Keep Krispie Treats Soft and Gooey
- Add sweetened condensed milk. The condensed milk adds a sweetness reminiscent of the milk left at the bottom of a bowl of Lucky Charms. Plus, it helps keep the treats soft!
- Melt the marshmallows slowly. The marshmallows should always be melted over low heat so they don’t burn or harden.
- Add a handful of mini marshmallows at the end. I like to add about a cup of mallows with the cereal that won’t quite melt all the way. This leaves lovely little pockets of gooey marshmallow in the treats.
- Don’t pat the treats down. I know it’s tempting to push the treats down into the pan, but please resist this urge! Patting the mixture down leads to hard, dense treats.
- Spray your hands with cooking spray and use them to gently spread the treats evenly out over the pan. No need to press them down.
Storage and Make Ahead Instructions
Lucky Charms Rice Krispie Treats are best served within 24 hours, but thanks to the sweetened condensed milk, they’ll last for 2-3 days.
Wrap cereal treats tightly in saran wrap to keep them soft. Do not refrigerate.

- If desired, save a few of the marshmallows from the Lucky Charms before mixing them into the bars. Press them gently on top of the finished bars for extra colorful treats.
