Why This is the Best Recipe

I love baking easy treats with cereal and think these are the best mini Lucky Charms krispie treats because:

  1. Just 3 Ingredients: Like most krispie treats, you only need 3 things to make it.
  2. Mini Cereal Texture: The Lucky Charms minis have a small, round cereal shape with the marshmallows mixed in and work even better than the traditional cereal would.
  3. Cute and Colorful: Who could resist a classic dessert made with rainbow marshmallows?

Ingredients

The box of Lucky Charms Minis is on the counter next to the butter and marshmallows.

All you need to make Lucky Charms treats is:

  1. Lucky Charms Minis: I think these are even better than traditional Lucky Charms, but you could use either one.
  2. Marshmallows: Buy the normal jet-puffed marshmallow size, not the minis.
  3. Butter: I used salted.

Lucky Charms Minis vs. Traditional Lucky Charms

If you've never purchased the Lucky Charms minis cereal, I wanted to give you a close-up look at the texture so you can see why this particular cereal is so perfect for making krispie treats.

See how the cereal base is almost Kix-like in shape?

Those small round puffs form a krispie treat with a much better flavor than traditional Lucky Charms.

Make the Marshmallow Creme

To make the krispie treats, start by making the marshmallow creme.

Spray a 9x13-inch baking pan with cooking spray and set it aside so you have some place to scrape the treats into immediately when they are ready.

Then, add the butter to a large pot set over medium-high heat.

Once the butter is completely melted add the marshmallows.

The large pot has marshmallows melting inside.

Gently stir the marshmallows and melt them down into the butter.

Be sure to scrape the bottom of the pot as you stir so everything mixes together.

The melted marshmallows are almost ready to have the cereal stirred in.

Once the marshmallows are completely smooth, remove the pot from the heat.

Immediately pour the Lucky Charms minis cereal into the marshmallow cream and stir to coat.

Use a spatula to scrape the mixture into your prepared 9x13-inch baking pan. It will be very sticky, work quickly while the treats are warm.

The baking pan has a clump of the krispie treats mixture ready to be smoothed out.

If you find your spatula and a large cooking spoon start to stick too much to the bars and you can't level them out into the pan nicely, run your hands under warm water and pat off as much excess water as you can with a clean towel.

Use your slightly dampened hands to pat the cereal into place. This only works once the marshmallow cream has cooled enough to just be warm to the touch, don't try it right out of the cooking pot or you'll burn your hands.

Cool completely before cutting into squares.

The treats have been smoothed into the 9 x 13-inch pan.

Make Ahead and Storage Tips

This is an excellent make ahead party treat recipe.

You can store the krispie treats at room temperature in an airtight container for up to 5 days.

They taste the best in the first day or two but my family had no problems finishing them off.
