I love how fun and colorful these Lucky Charms Treats turn out. They remind me of the classic rice krispie treats but with a magical twist from the marshmallow charms. They’re chewy, sweet, and a little crunchy, making them perfect for parties, holidays, or just a fun snack to whip up quickly.

Why You’ll Love This Recipe

I like this recipe because it’s so simple and comes together in minutes. The buttery marshmallow mixture binds everything perfectly, and the Lucky Charms cereal gives a nostalgic and playful vibe. I also love that I can add a drizzle of white chocolate on top for an extra special touch. These bars are always a hit with both kids and adults.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

▢6 Tablespoons (85 g) salted butter
▢10 oz mini marshmallows
▢½ teaspoon vanilla extract
▢8 cups (296 g) Lucky Charms cereal
▢2 oz (57 g) white chocolate bar finely chopped (for topping, optional)

Directions

  1. I start by greasing a 9×13-inch baking dish with butter or nonstick spray and set it aside.
  2. In a large pot, I melt the butter over low heat.
  3. I add the mini marshmallows and stir until they are completely melted and smooth.
  4. I stir in the vanilla extract.
  5. I remove the pot from the heat and gently fold in the Lucky Charms cereal until everything is evenly coated.
  6. I quickly transfer the mixture to the prepared baking dish and press it down gently with a buttered spatula or parchment paper. I make sure not to press too hard so the bars stay soft and chewy.
  7. If using, I melt the white chocolate and drizzle it over the top.
  8. I let the bars cool at room temperature until set, then slice into squares.

Servings and Timing

This recipe makes about 12–16 bars, depending on how large I cut them. It usually takes me around 10 minutes to prepare and about 30 minutes for them to fully set before serving.

Variations

I sometimes swap the white chocolate topping for colored candy melts to match a holiday theme. For extra flavor, I like mixing in a handful of colorful sprinkles. If I want a slightly less sweet version, I combine half Lucky Charms and half plain rice cereal.

Storage/Reheating

I store the bars in an airtight container at room temperature for up to 3 days. I avoid refrigerating them because it makes the marshmallows hard. If the bars start to firm up too much, I like microwaving a single square for 5–10 seconds to soften it slightly.

FAQs

Can I use unsalted butter instead of salted?

Yes, I can use unsalted butter, but I like adding a small pinch of salt to balance the sweetness.

Can I use large marshmallows instead of mini?

I can use large marshmallows, but they take a little longer to melt evenly. I usually cut them into smaller pieces first.

How do I keep the bars from sticking to my hands when pressing them into the pan?

I butter my hands or use parchment paper to press the mixture down without sticking.

Can I make these ahead of time?

Yes, I can make them a day in advance, and they still taste fresh if stored properly in an airtight container.

Can I freeze Lucky Charms treats?

I don’t recommend freezing them because the marshmallows lose their chewy texture.

What size pan works best?

I like using a 9×13-inch pan for thinner bars, but I sometimes use a smaller pan if I want them thicker.

Can I add mix-ins like candy or sprinkles?

Yes, I sometimes add sprinkles or mini chocolate chips, but I fold them in after the cereal mixture cools slightly so they don’t melt.

How do I make them extra gooey?

I reduce the cereal by about 1 cup and keep the same amount of marshmallows for a softer, gooier texture.

How do I cut neat squares?

I use a sharp knife and butter the blade lightly before slicing to avoid sticking.

Can I make these dairy-free?

Yes, I can use a dairy-free butter substitute and vegan marshmallows to make them dairy-free.

Conclusion

I love how easy and fun these Lucky Charms Treats are to make. They’re colorful, sweet, and always bring a little magic to the dessert table. Whether I’m serving them at a party or just making a batch for a quick snack, these bars never last long in my kitchen.
