Lucky Charms Cereal Bars Ingredients
- 1 Box of General Mills Lucky Charms Cereal, or you can use another brand; just look in the cereal aisle
- Marshmallows – use mini or regular marshmallows – they both melt the same and come in 10-ounce bags.
- Butter
- White chocolate or almond bark – I prefer using white chocolate for a better taste.
How to make Lucky Charm Bars
Step 1. Line the baking pan with parchment paper and spray with cooking spray. Make sure the paper extends over the sides of the pan so you can easily pull the bars out.
Step 2. This is optional, but I like adding marshmallows to the bars once they are in the pan to show off their shapes and colors. So, remove about ¼ cup of marshmallows from the cereal.
Step 3. Add the butter to a large pot and melt it over medium heat on the stovetop. Once the butter is melted, add the marshmallows and constantly stir until melted and smooth. Remove the pan from the heat.
Step 4. Pour the cereal mixture into the gooey marshmallows and stir well until fully incorporated.
Step 5. Pour mixture into the prepared 9×13 pan. Spread the mixture into an even layer using a greased spoon or spatula. Scatter the remaining marshmallows you pulled out from the cereal and gently press them into the top of the bars so they stick to them.
Marshmallow Tip
When working with melted marshmallows or marshmallow cream, spray your spoon or spatula with cooking spray to keep the marshmallow from sticking.
Step 6. Let the bars cool down and set (about 30 minutes to an hour.) Pull the bars out of the pan by lifting up the parchment paper. Place the whole sheet of bars on a cutting board, turn it upside down, remove the parchment paper, then turn it back over and cut the bars into even pieces.
Step 7. Add the white chocolate to a medium-sized bowl and melt in the microwave at 30-second increments, stirring between every 30-second increment. Continue until fully melted.
Tips
- Be sure not to overheat the white chocolate as it can seize. Melting in short bursts and stirring often ensures a smooth consistency.
- If you want the marshmallows within the bars to be more pronounced, don’t mix them in until the cereal has partially cooled. This way, they maintain their shape and texture.
- For an extra touch of festivity, consider topping the white chocolate with themed sprinkles or edible glitter before it sets.
- A pizza cutter can make slicing the bars into neat, even pieces easier than a knife.
- If the mixture is sticky when spreading in the pan, lightly greasing your hands can help you press down the mixture without it sticking to you.
Variations
- Chocolate Lovers’ Version: Mix half a cup of chocolate chips with the marshmallows when melting them. This variation adds an extra layer of chocolatey goodness to your cereal bars.
- Peanut Butter Twist: Stir a quarter cup of creamy peanut butter before adding the cereal to the melted marshmallows. This gives a subtle peanut butter flavor that complements the marshmallows perfectly.
- Fruity Fun: Swap half the amount of these fun Lucky Charms treats with your favorite fruit-flavored cereal for a colorful and fruity twist.
- Nutty Adventure: Add a half cup of chopped nuts (almonds, walnuts, or pecans work great) into the mix for an added crunch and nutty flavor.
- Double Marshmallow: For an extra gooey cereal bar, double the amount of marshmallows. Use half for melting and mix the other half whole into the bars.
- Birthday Cake Bars: Add a teaspoon of vanilla extract and a half cup of rainbow sprinkles into the melted marshmallow mix for a birthday cake-flavored celebration in every bite.
Recipe FAQ’s
You can; one 7-ounce jar of marshmallow cream equals about 2 ½ cups of mini marshmallows.
Absolutely! While Lucky Charms adds a unique flavor and color to the bars, you can experiment with various types of cereal according to your preference. Using a different cereal may alter the taste and appearance, but it’s a great way to personalize the recipe.
To make these cereal bars vegan, substitute the butter with a plant-based butter alternative and use vegan marshmallows. Look for a dairy-free version of white chocolate or replace it with a vegan-friendly alternative like dark chocolate without animal products

Storage
To ensure your Lucky Charms bars remain fresh and delicious, store them in an airtight container at room temperature. They will keep well for up to 5 days.
If you’re in a warmer climate and the bars seem a bit too soft, you can refrigerate them, which can help firm them up for a more satisfying chew. Simply bring them back to room temperature before serving for the best texture.
Remember, layering the bars between sheets of parchment or wax paper in the container can help prevent them from sticking together.

Lucky Charms Bars
Ingredients
- 5 cups Miniature marshmallows 10-ounce package, 283 grams
- 4 tablespoons unsalted butter 57 grams
- 6 cups Lucky Charms cereal
- 12 ounces White chocolate bar can use almond bark
Instructions
- Line a 9×13 baking sheet with parchment paper but let the paper come up above the pan so you can easily pull the bars out of the pan,. and grease it with nonstick cooking spray.
- Pull out about ¼ cup of the marshmallows from the cereal. You will add this to the top of the bars.
- In a large pot, melt the butter over medium heat. Once the butter is melted, add the marshmallows and stir constantly until melted and smooth. Remove the pan from heat.
- Add Lucky Charms cereal to the melted marshmallows and stir well until fully incorporated.
- Pour the cereal mixture into the prepared pan. Spread the mixture into an even layer using a greased spoon or spatula. Scatter the remaining marshmallows over the cereal gently pressing them into the top of the bars.
- Let the bars cool down and set (about 30 minutes to an hour.) Pull bars out of the pan by lifting up the parchment paper, then cut the bars into even pieces.
- If using a white chocolate bar, break the bar up into smaller pieces. Do the same if you are using almond bark, this will help the chocolate melt more evenly. Add the chocolate to a medium-sized microwavable bowl.
- Melt the chocolate in 30 second increments in the microwave, stirring between every 30 second increment. Continue until fully melted.Dip the bottoms of the bars into the chocolate, making sure to come up the sides of the bars just a bit so you can see it from the sides of the bars, then sit the bars on a sheet of wax paper to harden.
- Store the bars in an airtight container for up to five days. Or freeze for later.
