Lucky Charms Rice Krispie Treats Ingredients
• A colorful twist to your celebrations!
For the Base
- Lucky Charms Cereal – Adds a fun, colorful crunch; feel free to substitute with another fruity cereal if needed.
- Rice Krispies Cereal – Forms the crispy base; generic puffed rice works just as well if you prefer.
For the Mixture
- Mini Marshmallows – Essential for that fluffy sweetness; regular marshmallows can be used, but minis melt more evenly.
- Salted Butter – Gives richness and smoothness to the treats; unsalted butter can be an option if you want to control the saltiness.
- Green Gel Food Coloring – Makes your treats festive and eye-catching; optional if you’d like to stick with the classic look.
Optional Toppings
- Extra Mini Marshmallows – For an added chewy topping experience; they can be added before refrigerating.
Step‑by‑Step Instructions for Lucky Charms Rice Krispie Treats
Step 1: Prepare Your Baking Dish
Start by greasing a 9″x13″ baking dish with butter, ensuring it’s evenly coated to prevent sticking. This will help the Lucky Charms Rice Krispie Treats release easily after setting. Set the prepared dish aside as you move on to the melting process.
Step 2: Melt the Marshmallows
In a microwave-safe bowl, combine mini marshmallows and heat them in 20-second increments. Stir between each interval until they begin to melt, which should take around 40-60 seconds in total. Look for the marshmallows to appear puffy and partially melted, creating a soft, gooey mixture.
Step 3: Melt the Butter
In a separate microwave-safe bowl, add your salted butter and heat in the microwave in similar increments of 20 seconds. Once the butter is almost fully melted, it’s the perfect time to mix it with your marshmallow blend—this will help achieve a creamy consistency in your Lucky Charms Rice Krispie Treats.
Step 4: Combine Marshmallows and Butter
Pour the melted butter into the bowl with marshmallows, and microwave again for an additional 20 seconds. After warming, stir the mixture vigorously until it becomes smooth and well-combined. The heat will help bring everything together for that perfect treat consistency.
Step 5: Add Color to the Mixture
Before adding the cereals, incorporate green gel food coloring into your marshmallow mixture for a festive touch. Stir well until the color is evenly distributed, making your Lucky Charms Rice Krispie Treats come to life with a vibrant hue that’s perfect for St. Patrick’s Day celebrations.
Step 6: Mix in Cereals
Fold in Rice Krispies and Lucky Charms cereal gently into the marshmallow mixture. Use a spatula to ensure that every piece of cereal is well-coated in the sweet, gooey mixture. This step should be done carefully to maintain the crispy texture of the cereals.
Step 7: Transfer to Baking Dish
Using your buttered spatula, transfer the colorful mixture into the greased baking dish. Spread it evenly across the surface, pressing down gently to create an even layer. Ensure the mixture fills all corners of the dish, forming a solid base for your Lucky Charms Rice Krispie Treats.
Step 8: Add Mini Marshmallows on Top
If desired, sprinkle additional mini marshmallows on top of the mixture while it’s still warm. Gently press them down to ensure they stick. This step adds extra sweetness and a lovely visual appeal to your festive Lucky Charms Rice Krispie Treats.
Step 9: Chill and Cut the Treats
Refrigerate the mixture for at least 30 minutes, allowing it to set and firm up. Once chilled, remove from the fridge and use a buttered knife or spatula to cut the treats into squares. This method helps achieve cleaner edges and beautifully presented portions ready for sharing.

Make Ahead Options
These Lucky Charms Rice Krispie Treats are ideal for meal prep enthusiasts looking to save time during busy celebrations! You can prepare the cereal mixture up to 24 hours in advance. Simply follow the first six steps of the recipe and then store the combined marshmallow and cereal mixture in an airtight container at room temperature.
