Steps to Make Lucky Charms Marshmallow Treats
- Line a 9×13-inch baking pan with parchment paper. Set aside until ready to use. Melt unsalted Irish butter in a large stock pot over low heat. Then, pour in the mini marshmallows.
- Stir constantly with a silicone spatula until the marshmallows have melted and the mixture is smooth and well combined.
- Remove from the heat and pour in the Lucky Charms Cereal.
- Quickly and carefully stir with a silicone spatula to coat all of the cereal with the marshmallow mixture. Take care not to crush the cereal when stirring.
- Transfer the mixture to the prepared pan.
- Spray your hands with non-stick cooking spray and gently press the mixture evenly into the pan. If you press too hard, you’ll end up with hard marshmallow treats. Allow to cool for about 30 minutes before topping.
- After the marshmallow treats have cooled, melt bright white and green candy melts, seperately, in the microwave according to package directions. Pour the white candy melts over the top of the Lucky Charms treats.
- Then, use a silicone spatula to smooth into an even layer.
- Next, drizzle the green candy melts over the white.
- Use a thin wooden skewer or knife to swirl the white and green together.
- Top with extra Lucky Charms Marshmallows and gold sanding sugar.
- Allow the candy melts to harden completely, for about an hour. Then, remove from the pan and cut into squares.
Experience the iconic marshmallow charms in every bite! Lucky Charms Marshmallow Treats offer a quick and easy way to enjoy that classic marshmallow and cereal combination. They are the perfect no-bake, kid-friendly snack.
Recipe Tips and Tricks
- I was able to find a bag of Lucky Charms Just Marshmallows at Target. If you can’t find them, I recommend buying a second box of Lucky Charms and picking the marshmallows out to decorate the top with.
- If the candy melts begin to harden too quickly while swirling or topping with extra marshmallow and sanding sugar, pop the pan in a 300°F oven for a few minutes to melt again.
