Ingredients Needed for This lucky charms rice krispie treats Recipe
Here’s what you’ll need to create your own batch of magical Lucky Charms Rice Krispie Treats. I like to make sure I have everything ready to go before I start, which makes the whole process even smoother and so much more efficient.
- 6 tablespoons unsalted butter
- 10 ounces marshmallows (about 40 large), plus extra for topping
- 1/4 teaspoon salt
- 6 cups Rice Krispies cereal
- 6 cups Lucky Charms cereal, divided (reserve 1 cup of marshmallows for topping)

How to Make This lucky charms rice krispie treats Recipe
Here are those steps for making this family favorite. You can easily adapt for gluten-free diets by checking the labels on your marshmallow and cereal items.
- 1. Prepare your pan: Grease a 9×13 inch baking pan with butter or cooking spray. This prevents sticking and makes it easier to remove the treats later.
- 2. Melt the butter: In a large saucepan or dutch oven, melt the butter over medium heat. This is where you set the stage for that delicious, buttery flavor.
- 3. Add marshmallows and salt: Add the marshmallows and salt to the melted butter. Stir constantly until the marshmallows are completely melted and smooth. This creates the gooey base that holds everything together. Removing from the heat helps to control how fast the marshmallows cook.
- 4. Combine cereal: Pour in the Rice Krispies cereal, and half of the Lucky Charms cereal (5 cups). Stir until the cereals are evenly coated with the marshmallow mixture. Quick tip: Gently fold the cereal in to avoid crushing it.
- 5. Transfer to pan: Pour the mixture into the prepared pan and gently press it down to create an even layer. Don’t pack it too tightly; you want to keep those treats nice and airy.
- 6. Add marshmallow topping: Sprinkle the reserved Lucky Charms marshmallows (from the remaining 1 cup of cereal) on top, pressing them down lightly into the surface.
- 7. Cool and cut: Let the treats cool completely in the pan before cutting them into squares. This usually takes about 30 minutes to an hour. You can speed this up by placing them in the refrigerator if you want to enjoy them faster.
How to Serve This lucky charms rice krispie treats Recipe
These marshmallow cereal treats are incredibly versatile! You can serve them as a snack, a dessert, or even pack them in lunchboxes. For an extra touch, cut them into fun shapes using cookie cutters or serve them alongside a scoop of vanilla ice cream. Consider serving with milk as well for a nostalgic treat.
How to Store This lucky charms rice krispie treats Recipe
To keep your Lucky Charms Rice Krispie Treats fresh and delicious, store them in an airtight container at room temperature. They’ll stay good for about 2 to 3 days. I would not recommended freezing this recipe as it will cause the marshmallows to become freezer burnt.
Tips to Make This lucky charms rice krispie treats Recipe
- Don’t overcook the marshmallows: Overcooked marshmallows will result in hard, brittle treats. The goal is to melt them until they’re just smooth and creamy.
- Use fresh marshmallows: Fresh marshmallows melt more easily and create a better texture. If your marshmallows are a little stale, consider adding a tablespoon of butter or water to the mixture.
- Gently press the mixture: When pressing the treats into the pan, use a sheet of parchment paper or wax paper to prevent sticking and ensure an even surface. Press gently to avoid compacting the treats too much.

Helpful Notes for This lucky charms rice krispie treats Recipe
- If you want your treats to be extra gooey, reserve about a cup of marshmallows and stir them in after melting the rest for melted pockets of marshmallow goodness!
- For a richer flavor, use browned butter. Simply cook the butter a little longer until it turns a golden brown color and smells nutty before adding the marshmallows.
- You can easily double this recipe if you’re making it for a crowd. Just use a larger pan.
Variation of This lucky charms rice krispie treats Recipe
- St Patrick’s Day Dessert Edition: Add a few drops of green food coloring to the marshmallow mixture for a festive St Patrick’s Day dessert.

How do you keep rice krispie treats from getting too hard?
To prevent hard rice krispie treats, use fresh marshmallows and melt them over low heat. Avoid overcooking the marshmallow mixture and gently press the treats into the pan rather than packing them tightly.

Yes, you can substitute different cereals for a unique twist on the classic treat. Other marshmallow cereals like Fruity Pebbles or Cocoa Krispies work well, offering different flavors and colors.
How long do lucky charms rice krispie treats stay fresh?
Lucky charms rice krispie treats generally stay fresh for about 2-3 days if stored in an airtight container at room temperature. They are best enjoyed soon after making them to maintain their soft and chewy texture.
