What You’ll Need

- 6 Tablespoons (85 g) salted butter (plus extra for greasing the pan)
- 10 oz mini marshmallows (about 5 cups)
- ½ teaspoon vanilla extract (for added flavor)
- 8 cups (296 g) Lucky Charms cereal (feel free to add more marshmallows from the box if desired)
- 2 oz (57 g) white chocolate bar, finely chopped (optional, for topping)
How to Make Lucky Charms Treats
- Prepare the pan: Lightly grease a 9×13” (23x33cm) pan with butter and set aside.
- Melt the butter: Place 6 Tablespoons (85 g) of salted butter in a large pot and melt over low heat.
- Add marshmallows and vanilla: Once the butter is melted, add 10 oz of mini marshmallows and ½ teaspoon of vanilla extract. Stir continuously until the marshmallows are completely melted and smooth.
- Incorporate the cereal: Remove the pot from heat and add 8 cups (296 g) of Lucky Charms cereal. Gently stir until all the cereal is evenly coated with the marshmallow mixture.
- Press into the pan: Immediately spread the mixture evenly into the prepared pan. Press gently to avoid packing the cereal too tightly, which can make the treats dense.
- Cool completely: Allow the treats to cool at room temperature until set.
- Optional topping: If desired, melt 2 oz (57 g) of finely chopped white chocolate in the microwave (heat in 20-second intervals, stirring well in between) and drizzle over the cooled treats.
- Cut and serve: Once fully cooled and set, cut into squares and enjoy!
Creative Topping Ideas to Elevate Your Treats
While the optional white chocolate drizzle adds a sweet touch, why not get creative with toppings? Try drizzling melted dark chocolate or caramel sauce for a richer flavor. For a festive twist, sprinkle rainbow sprinkles or crushed graham crackers on top before the mixture sets. These small additions can make your Lucky Charms Treats even more magical!
Perfect Serving Suggestions for Any Occasion
These treats are perfect for parties, lunchboxes, or a quick snack. Cut them into bite-sized squares for easy sharing or larger rectangles for a satisfying treat. Pair them with a glass of cold milk or a scoop of vanilla ice cream for an indulgent dessert. They’re also a hit at themed parties—think St. Patrick’s Day or unicorn-themed celebrations!
Storage Tips to Keep Your Treats Fresh
Store your Lucky Charms Treats in an airtight container at room temperature for up to 3 days. If you’re in a warmer climate, consider refrigerating them to prevent the marshmallow mixture from becoming too soft. For longer storage, wrap individual pieces in plastic wrap and freeze for up to 2 weeks. Let them thaw at room temperature before serving.
Quick and Easy Recipe Variations
Want to mix things up? Swap out Lucky Charms for another cereal like Fruity Pebbles or Cocoa Puffs for a different flavor profile. You can also add mix-ins like mini chocolate chips, chopped nuts, or dried fruit for extra texture. For a nut-free option, stick to the classic recipe or use seeds like sunflower seeds as a crunchy alternative.
Time-Saving Tips for Busy Bakers
To speed up the process, use a microwave-safe bowl to melt the butter and marshmallows in 30-second intervals, stirring in between. This eliminates the need for a stovetop and cuts down on cleanup. Pre-measure your ingredients before starting to ensure a smooth and efficient cooking experience. These small adjustments can save you precious time without compromising on taste!
