Ingredients You’ll Need
Here’s everything required to make these sweet cereal treats:
- Lucky Charms cereal
- Marshmallows
- Butter
- 1/4 teaspoon fine sea salt
- 1 teaspoon pure vanilla extract
- 1/4 cup rainbow sprinkles (optional)
Each ingredient plays a role: the butter and marshmallows create that classic gooey base, while the vanilla and salt enhance the sweetness without overpowering it.
How to Make Chewy Lucky Charms Marshmallow Treats (Step-by-Step)
Step 1: Melt the Base
In a large pot, melt the butter over low heat. Add the marshmallows and stir gently until completely melted and smooth.
Step 2: Add Flavor
Remove the pot from heat. Stir in the vanilla extract and sea salt to balance the sweetness.
Step 3: Mix in the Cereal
Gently fold in the Lucky Charms cereal until evenly coated. If using sprinkles, add them now and mix lightly.
Step 4: Shape the Treats
Press the mixture into a parchment-lined pan. Lightly butter your hands or a spatula to prevent sticking.
Step 5: Cool and Slice
Let the treats cool for about 30 minutes, then cut into squares and enjoy.
Tips & Variations
- Extra chewy texture: Stir in an additional half cup of marshmallows at the end.
- Less sweet option: Replace one cup of cereal with plain puffed rice.
- Dairy-free version: Use plant-based butter and dairy-free marshmallows.
- Holiday fun: Swap sprinkles for themed colors to match the season.
Serving Ideas & Storage
Serve these treats on a colorful platter for parties or pack them individually for school snacks. Store leftovers in an airtight container at room temperature for up to three days to keep them soft and chewy.

Easy Chewy Lucky Charms Marshmallow Treats
- Total Time: 45 minutes
- Yield: 16 squares 1x
Description
Chewy Lucky Charms Marshmallow Treats are a colorful, no-bake twist on classic cereal bars. Gooey melted marshmallows coat crunchy Lucky Charms cereal (including the fun marshmallow shapes) for a kid-friendly snack that’s perfect for school parties, holidays, and quick sweet cravings.
Ingredients
4 tbsp (57 g) unsalted butter, plus more for greasing
10 oz (283 g) mini marshmallows
1 tsp pure vanilla extract
1/4 tsp fine sea salt
6 cups (about 180 g) Lucky Charms cereal
1/4 cup rainbow sprinkles (optional)
Instructions
1. Line a 9×13-inch pan with parchment paper (or lightly butter it).
2. Melt the butter in a large pot over low heat.
3. Add the mini marshmallows and stir until fully melted and smooth.
4. Remove from heat; stir in vanilla and sea salt.
5. Add Lucky Charms cereal and fold gently until evenly coated.
6. Fold in sprinkles (optional) just until mixed (don’t over-stir).
7. Press the mixture into the prepared pan using a buttered spatula or lightly buttered hands.
8. Let cool 30 minutes, then slice into squares and serve.
Notes
For extra-chewy treats, add 1–2 cups mini marshmallows after removing the pot from heat, then mix in cereal.
To reduce sweetness, swap 1 cup of Lucky Charms for 1 cup plain puffed rice cereal.
Press gently—packing too hard can make bars dense instead of chewy.
Storage: Keep airtight at room temperature for up to 3 days (best texture in the first 24–48 hours).
Optional: Add 2 tbsp colorful candy bits or mini chocolate chips after cooling slightly.
