Ingredient Notes
Find the full printable recipe with specific measurements below.
- Lucky Charms Cereal: The star of the show, but you could make these bars with any cereal.
- Mini Marshmallows: You can use large marshmallows, but they will take longer to melt. Use soft and fresh marshmallows so the bars turn out soft and chewy, old marshmallows tend to be stale and dry.
- Butter: If you choose to use salted butter, only add an additional 1/4 teaspoon of salt. For an added depth of flavor, you can brown the butter for a slightly nutty flavor. Follow these directions for how to brown butter before adding in the marshmallows.
- Salt: A pinch of salt is optional, but it helps to balance the sweetness.

How to Make Lucky Charms Rice Krispie Treats
Visit the recipe card below for the full directions.
Melt butter first. Let the butter fully melt before adding marshmallows so everything combines evenly and doesn’t scorch.
Use fresh marshmallows. Fresh marshmallows melt smoother and create a softer, chewier texture. Stale marshmallows can make the treats dry and stiff.
Keep the heat low. Melt the marshmallows over low heat to prevent them from becoming tough. Slow and steady makes a big difference.
Don’t overmix. Stir just until the cereal is coated. Over-mixing can crush the cereal and make the bars dense.
Press gently into the pan. Lightly butter your hands or spatula and gently press the mixture down. Pressing too firmly can make the treats hard.
Line your pan. Use parchment paper or foil for easy removal and cleaner slices.
Slice with a buttered knife. Lightly grease your knife to get clean cuts without sticking.
Make Ahead and Storing
You can store these treats for up to 5 days in an airtight container at room temperature. Just make sure they’re totally cooled to room temp prior to storing so you don’t have any condensation form in the container!
I like to keep them in a zip-top gallon bag with little parchment paper squares separating them. That way, they don’t all stick together.
