Ingredients for Lucky Charms Rice Krispie Treats
The beauty of Rice Krispie treats lies in their simplicity. With just a few basic ingredients, you can create something truly delightful. Here's what you'll need:
- 6 cups of Lucky Charms cereal: The foundation of your treats, providing the crunch we all love.
- 4 cups of mini marshmallows: For that stretchy, gooey texture that holds everything together. Mini marshmallows melt more evenly than large ones.
- 6 tablespoons of unsalted butter: Adds richness and helps bind the ingredients together.
- 1 teaspoon of vanilla extract (optional): Enhances the flavor and adds a touch of warmth.
How to Make Lucky Charms Rice Krispie Treats
Step 1 Begin by lightly greasing a 9x13-inch baking pan with butter or non-stick spray. This prevents the treats from sticking and makes for easy removal later.
Step 2 In a large saucepan, melt the butter over low heat. Once melted, add the mini marshmallows, stirring continuously until they are completely melted and smooth. If desired, stir in the vanilla extract for an extra layer of flavor.

You can also do this step in a microwave using a large microwave safe bowl.
Remove the saucepan from heat and quickly add the Rice Krispies cereal. Stir until the cereal is thoroughly coated with the marshmallow mixture.
Step 3 Pour the mixture into your prepared pan. Use a buttered spatula or wax paper to press the mixture evenly into the pan. Be careful not to press too hard, as this can make the treats too dense.

Step 4 Allow the treats to cool at room temperature for at least 30 minutes. Once set, cut them into squares or rectangles and enjoy!

To make them in a microwave add marshmallows and butter to a microwave safe bowl. Cook in the microwave for 2 minutes and then stir. Add cereal treats.

Pro Tips for Lucky Charms Rice Krispie Treats
- Use fresh marshmallows for the softest texture.
- Melt the marshmallows over low heat to prevent them from becoming tough.
- Do not overmix the cereal mixture once combined.
- Lightly grease your spatula before pressing the mixture into the pan.
- Save a handful of Lucky Charms marshmallows to sprinkle on top for a decorative finish.
- Let the treats cool completely before slicing for cleaner cuts.
- Use a sharp knife sprayed with cooking spray for neat squares.
Storage
Store Lucky Charms Rice Krispie Treats in an airtight container at room temperature for up to 3 days.
For best results, place sheets of parchment paper between layers to prevent sticking.
Avoid refrigerating the treats, as refrigeration can cause them to become firm and lose their soft texture.
If you need to make them ahead of time for a party or event, prepare them the day before and store them tightly covered at room temperature.

These colorful treats are perfect for a variety of occasions.
- Serve at St. Patrick's Day parties.
