How to Make Lucky Charms Treats
To get started, spray a 9x9 inch pan and gather all your ingredients.
- Step 1: Melt the Butter and Marshmallows. Use a microwave-safe bowl to melt the butter. Stir in the mini marshmallows and microwave for 30 seconds at a time, stirring until they are fully melted.
- Step 2: Add the Vanilla. Stir in the vanilla extract.
- Step 3: Add the Lucky Charms. Stir well until the cereal is completely covered in the marshmallow mixture.
- Step 4: Pour Into the Pan. Pour the mixture into the pan and press it down gently. If needed, you can put a little water or cooking spray on your hands to keep the cereal from sticking. Let the treats set for 30 minutes before serving.
Hint: Donโt Crush the Cereal
Be gentle when putting the cereal and marshmallow mixture in the pan. Press it down carefully so you donโt crush the Lucky Charms.

Expert Tips
- Work Quickly: Once the marshmallows melt, you'll want to add the cereal immediately and mix everything together quickly before it sets.
- Sticky Fingers: You can lightly coat your hands and spatula with cooking spray to avoid the marshmallow-coated cereal from sticking to your hand.
- For the Best Texture: Don't press down too hard when pressing the mixture into the pan, otherwise it can make Lucky Charm cereal bars too dense, compact, and hard to chew.
- Clean Lines: If you want the perfect squares, let the treats cool for 30 minutes and then use a knife sprayed with cooking spray to cut each square. Wipe the knife clean between cuts.
Storing Leftovers
- Storing: Leftover Lucky Charms marshmallow treats keep in an airtight container for up to 3-4 days. Place parchment paper between layers to prevent the bars from sticking to each other.
- Make Ahead: These treats are perfect for making 1-2 days ahead of parties or events. Allow them to set completely before cutting and storing in an airtight container.

Recipe FAQs
Mini marshmallows are the best choice for a smooth and creamy mixture. Regular-sized marshmallows can be used, but they may take longer to melt and create a lumpier texture.
You can customize the cereal to your taste buds! Try Fruity Pebbles, Cinnamon Toast Crunch, or any of your favorite cereal brands.
