My family loves gooey marshmallow treats. Give us a tray of perfectly soft and stretchy marshmallow bars, and it will be gone that day.

But we also love changing it up and using different cereal to give our favorite rice krispie treats a fun twist.

Our favorite cereal to use is the star of this recipe. And these Extra Gooey Lucky Charms Treats really are magically delicious.

They are loaded with gooey marshmallows, perfectly soft and stretchy pieces, and fun cereal shapes that will give everyone good luck all day long.

Making a large pot of these Lucky Charms Treats is always a fun treat on days when you need an easy recipe to bring some magic to your day.

What ingredients are in lucky charms treats?

  • Butter: this helps remove the cereal bars from the pan and lets you melt marshmallows without them sticking to everything else
  • Bag of Marshmallows: you can use mini marshmallows or large marshmallows, either one works, but the mini ones melt faster
  • Lucky Charms Cereal: this is the main ingredient! I recommend using the regular variety with the cereal mixture, not the marshmallow only box of lucky charms

Pro Tip: If you love marshmallow treats, try these other versions!

How to make lucky charms treats:

  1. Butter the pan you will set your lucky charms bars in.
  2. Pour cereal into a large bowl.
  3. Combine butter and marshmallows in a large microwave safe bowl.
  4. Melt butter and marshmallow mixture in the microwave, stirring with a rubber spatula every 30 seconds.
  5. Stir to finish melting the marshmallows, then pour over cereal.
  6. Mix until nice and gooey, then pour into the prepared baking dish.
  7. Press cereal treats into the edges of the pan; if it is too sticky to press into the corners, rub a little butter on your hands and then press down.
  8. Cool, cut and serve!

Pro Tip: For thicker lucky charms squares, use a smaller square pan. For extra thin lucky charm rice krispies, us a large cookie sheet with an edge. Just be sure to butter or spray the pan you use well so the lucky charm treats come out easily.

What is the secret to gooey lucky charms treats?

Some people think that lucky charms extra marshmallows added is the secret to perfectly gooey lucky charms treats. But it’s not.

The secret to a perfect lucky charms marshmallow treats recipe is to not overcook your marshmallows.

If you cook your marshmallows past when they are already melted, you will have dry, crispy treats.

If you cook your marshmallows until you have a few lumps, pull them off the heat and stir until they are melted the rest of the way, you will have the most perfect gooey marshmallow goodness in your bars.

How to serve lucky charms treats:

If you are serving these lucky charms treats to more than just happy children in your kitchen, there are a few ways you can do that to make it easier for your guests.

  • Wrapped in Plastic Wrap. Cut individual servings into squares or triangles and wrap lucky charms rice krispie treats completely in plastic wrap. No one can touch another person’s piece, everyone’s serving size is the same, and they won’t stick together.
  • Folded in parchment packets. Cut squares of parchment paper and fold each corner in, securing the corners with a sticker at the center. This is a great individual serving option for people who prefer not to use extra plastic, but it is not as airtight as using plastic wrap.
  • Layered on a tray with parchment paper dividers. If you want to stack your lucky charms rice krispies into a tower or are just making multiple layers at a time, place a piece of parchment paper between layers so the treats stay divided but you can quickly remove a layer to serve the next set.
  • Straight out of the tray. This easy transport treat is a perfect dish to serve from the pan you set it in. Just be sure to cut the pieces before serving. And to make it even easier, pull the first piece out or eat it yourself so people can easily get the next pieces out of the pan.

How to store lucky charms treats:

While you can store these lucky charms treats in the fridge, they will get harder there. For the best, gooey texture even days after making them, store these in a covered container on the counter at room temperature.

Are lucky charms treats gluten free?

Yes lucky charms treats are gluten free! Be sure you are using the Original Lucky Charms cereal from General Mills, because those are definitely gluten free and safe to serve your friends and kids who need to eat gluten free.

Are lucky charms treats peanut free?

Yes these lucky charms treats are naturally peanut free! They are the perfect crispy treats to bring someone who has a peanut allergy.

Can I freeze lucky charms treats?

Yes you can freeze lucky charms treats! You want to wrap each treat square completely in plastic wrap, and then put each piece in a zip bag in the freezer. Pull it out when you are ready and you have a treat on the go.

Pro Tip: Keeping lucky charm rice krispie treats in the freezer for a long time can change the texture of the cereal. Sometimes it can get grainy or soggy depending on how long it has been in there. For best results, do not freeze for more than 1 month before eating.

How long do lucky charms treats last?

At my house, Lucky Charms Treats only last 4 hours. They don’t usually get the chance to set because everyone loves them so much. But lucky charms marshmallow treats usually can last on the counter for 2-3 weeks.

Can dogs eat lucky charms treats?

Dogs can eat every ingredient in these lucky charms treats, but your vet will probably not like it since it isn’t very healthy for your dog. If your dog accidentally gets a bite, there is nothing toxic in this recipe, but there is nothing good for your dog either.
