Why you’ll love Lucky Charms Treats 🍀
Easy recipe – They’re no bake & couldn’t be easier. You can never have too many no bake recipes, especially when life gets busy.
Adorably festive – Bright and colorful, these cheery lucky charms treats are just as fun to look at as they are to eat!
Extra marshmallows – The lucky charms themselves are marshmallows, and we’re using traditional white marshmallows too for extra gooey, buttery goodness.
Simple ingredients – You need just 5 ingredients and that’s if you include extra sprinkles on top!
Things you’ll need
- Large Pot
- 9×13 Baking Dish – love that it has a lid for storing.
- Silicone Spatulas – the gooey marshmallows don’t stick to these as much.
- Lucky Charms Marshmallows – just the marshmallows, optional for topping.
Ingredients
Below is a list of the ingredients you’ll need to gather to make this recipe. Scroll all the way down for the full recipe card.
- Unsalted Butter – Melted butter helps melt the marshmallows into a smooth mixture. Once it cools and set the butter solidifies but helps keep the texture nice and chewy.
- Salt – Adding salt is necessary to balance out the sweetness of basically everything else in this recipe! If you end up using salted butter, skip the added salt.
- Mini Marshmallows – I use mini just because, but you can use regular marshmallows if preferred. As long as it all gets melted, it works.
- Lucky Charms Cereal – A throwback cereal that’s been around for decades. It’s made of oat cereal in various shapes symbolizing luck (horseshoes, clovers, hearts, etc.). The colorful marshmallows represent the same thing and together make a crunchy, chewy, rainbow treat.
- Lucky Charms Marshmallows – Packages of these can now be found sold separately. No more having to pick out the marshmallow charms one by one! Although, if you can’t find any online, or in store, get to diggin’!
- Rainbow Sprinkles – An optional way to top your lucky charms treats for a bit of extra color.
How to make Lucky Charms Treats
- Step One: Melt the butter in a large pot over low heat, then stir in the salt (if using unsalted butter). Add in the marshmallows and stir constantly until marshmallows have melted and it is mostly smooth. Be careful not to overdo it and cause it to burn.
- Step Two: Remove the pot from the heat and gently fold in the cereal until it’s all completely and evenly coated. It will be sticky and may need some extra arm strength.
- Step Three: Spread the cereal mixture into a prepared 9×13 baking dish, but do not pack it down otherwise your treats will end up hard. Immediately add extra lucky charms marshmallows and rainbow sprinkles on top before it sets.
- Step Four: Let it sit at room temperature for 30-60 minutes until it has cooled and set. Cut into bars as big or as little as you’d like. Enjoy!
What to serve with Lucky Charms Bars
I’d say these are the perfect ending to a slow cooker corned beef and potatoes dinner!
Add these no bake Irish potato candies to your dessert tray as well and invite everyone to sample one or two of each.
Tips & Suggestions 🍀
- Add a splash of pure vanilla extract to your melted marshmallows for added flavor.
- For best results, keep the heat really low when melting the marshmallow mixture.
- Don’t forget to grease your baking dish. These sticky squares won’t stay intact if they are stuck to the pan.
- Make sure to use fresh marshmallows. Stale ones just won’t cut it.
- Use a silicone or rubber spatula to help you gently press the mixture into th bottom of the pan.
- Lightly spray your hands with non stick cooking spray if you are using them to gently spread the marshmallows into the dish. It will help prevent the mixture sticking to your hands.
How to store leftovers
These are best enjoyed the same day they’re made but any leftover bars can be kept in an airtight container.
How long will they last in the fridge?
No need to refrigerate these! I actually recommend you don’t as they can harden up.
These easy treats can be kept at room temperature for up to 2 days. They’ll be eaten long before then, so don’t worry!
FAQs
Can I cut this recipe in half?
Certainly. Use half of the ingredients and use an 8 x 8 baking dish. Either that or make two smaller batches. One for you and one for a friend.
Are lucky charms treats gluten free?
They are! The oat cereal is gluten-free, as are the lucky charms marshmallows. Just make sure to read the label on the mini marshmallows, although most are gluten-free.
How many marshmallows will I need?
If you’re using mini marshmallows, you’ll need about 10 oz which equals about 6 cups. If using regular marshmallows you will need about 40.
