These Lucky Charms Rice Krispie Treats are surprisingly delicious and are a fun treat to make with kids. Combine Lucky Charms and gooey marshmallows to make treats perfect for birthday parties, St. Patrick's day, or a school snack. Add a cup of Rice Krispies in addition to the Lucky Charms cereal to fill in the holes and add texture.
I've always made cereal treats over the stove top and ended up with a big sticky mess. This easy recipe is great because all you need is one large bowl and a microwave. Adding Lucky Charms cereal and marshmallows is a fun way to elevate the classic Rice Krispie treat. You can also trade out the box of Lucky Charms or Rice Krispies for your favorite cereal, like Fruity Pebbles or Cocoa Puffs.
Lucky Charms Rice Krispie Treat Ingredients
Butter is the ingredient that adds flavor to the Lucky Charm treats. I like to use unsalted butter and add my own salt because I can control the amount, but you can also use salted butter and leave out the salt.
Large or mini marshmallows will work for this recipe, just make sure that they are fresh, and not expired.
Rice Krispies are a fun twist to this recipe, as most Lucky Charms treats will only use that cereal. I like the extra rice krispies because they fill in the gaps between the lucky charms cereal and marshmallows. It only takes about a cup of cereal to fill in the gaps, but if you like firmer crispy treats, you can add more.
Lucky Charms cereal has fun, colorful marshmallows that take this gooey marshmallow treat up a notch. They do melt a little bit when you mix them in with the hot marshmallows, so be sure to reserve a few for topping the treats.
Making Lucky Charms Rice Krispie Treats
- Grease a 9" x 9" pan with butter or nonstick cooking spray. You can also line it with a piece of parchment paper if you're nervous about sticking. A square pan will make thick Rice Krispie treats, while a rectangle pan will make thinner treats.
- Spray a large mixing bowl with cooking spray, add the marshmallows, and microwave in 30-second increments until they're melting and puffy. You can also heat them in a large saucepan over the stove.
- Grease your spatula with cooking spray or oil to help with the sticking and work quickly.
- Add the butter and salt to the marshmallows and mix them together until they are melted and combined.
- Reserve a few of the colorful marshmallows for topping, then add the Lucky Charms and Rice Krispies, one cup at a time, to the melted marshmallows and stir it all together.
- Pour the cereal mixture into the prepared baking dish and press it into an even layer with a spatula. Pro-tip: Coat your clean hands in cooking spray and press it into the corners.
- Sprinkle the reserved Lucky Charms marshmallows on top while the treats are still warm, then let them rest in the pan until they come to room temperature, or freeze for 20 minutes to set up.
- Release the edges of the treats with a knife, then remove them from the pan and cut them into 9 equal squares.
- Store the Lucky Charms Rice Krispie treats in an airtight container, or wrap individual treats in plastic wrap. They can last at room temperature for up to 3 days. Pro-Tip: For best results, leave them out overnight so the marshmallows get a little bit soggy, the texture is amazing!
- For an extra optional design, drizzle or dip each treat in white chocolate.
FAQ
Old marshmallows don't melt as well as fresh marshmallows because they develop a skin on the outside, so it's best to use a new bag for Krispie treats.
Adding too much butter and marshmallow to Rice Krispie treats can make them soggy, overly sticky, or even wet. Too little can make them dry and crumbly. If you like this recipe is a bit too gooey, add another ½ cup of Rice Krispies.
These treats are best served within 3 days. They can stay out at room temperature wrapped in plastic or wax paper, or stored in an airtight container. They will get hard if you refrigerate them.
