How to Make Lucky Charms Rice Krispie Treats
- Prep the Pan: Lightly butter a 9×13-inch baking dish and set aside.
- Melt the Marshmallows: In a microwave-safe bowl, heat the mini marshmallows in 20-second bursts until soft.
- Melt the Butter: In a separate bowl, microwave the butter in 20-second intervals until nearly melted.
- Combine: Stir the melted butter into the marshmallows and microwave again for 20 seconds. Mix until smooth.
- Add Color: If using, stir in green gel food coloring until evenly distributed.
- Fold in Cereals: Add the Rice Krispies first, mix to coat, then gently fold in the Lucky Charms.
- Spread in Pan: Transfer mixture to the prepared pan and spread evenly using a buttered spatula.
- Top it Off: Press extra Lucky Charms marshmallows onto the top for extra flair.
- Set & Slice: Refrigerate for 30 minutes, then slice into squares. Makes 12 standard-size treats, or 8 large ones.
Tips to Get Them Just Right
• Don’t Overheat: Melting marshmallows too long can make treats hard instead of chewy
• Work Quickly: Once cereals are added, spread the mixture fast before it sets
• Add Color Early: Mix food coloring into melted marshmallow before adding cereal for best distribution
• Use Fresh Marshmallows: They melt better and give a smoother texture
• Butter Your Tools: A buttered spatula or your hands will prevent sticking during shaping
Serving Ideas & Fun Variations
• Drizzle with White Chocolate: Add a sweet and creamy finish
• Make it Fruity: Mix in freeze-dried strawberries or blueberries for a tangy contrast
• Holiday Swap: Use red and green food coloring and themed marshmallows for Christmas
• Turn into Pops: Insert popsicle sticks into squares and wrap in cellophane for party favors
• Pair With: Hot cocoa, vanilla milkshakes, or a scoop of rainbow sherbet

Frequently Asked Questions
1. Can I make Lucky Charms Rice Krispie Treats without food coloring?
Yes, absolutely! The green gel food coloring is purely optional and often used for St. Patrick’s Day-themed treats. Skipping it won’t affect the flavor or texture. You’ll still have a colorful dessert thanks to the Lucky Charms marshmallows.
2. How long do these treats last?
Lucky Charms Rice Krispie Treats stay fresh for up to 3 days when stored in an airtight container at room temperature. For best texture, avoid refrigerating for too long as they may become too firm.
3. Can I freeze Lucky Charms Rice Krispie Treats?
Technically, yes — but it’s not recommended. Freezing can change the texture of the marshmallows, making the treats less chewy and more brittle. They’re best enjoyed fresh within a few days of making.
4. Can I use large marshmallows instead of mini marshmallows?
Yes! You can substitute large marshmallows for mini ones — just be sure to measure by weight (around 10.5 oz total) and chop them for easier melting. Mini marshmallows melt more evenly, but both types work well in this recipe.
