Equipment

1 square pan

Ingredients

16 ounces marshmallows large or small
½ cup unsalted butter plus more for the pan, or spray
½ teaspoon salt
1 teaspoon vanilla extract
1 cup Rice Krispies cereal
6 cups Lucky Charms cereal

Instructions

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!

Notes

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.
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.
Although this recipe is in cups too, I HIGHLY recommend you measure your ingredients using a food scale. It makes baking so much easier and will lead to more successful recipes. Follow my tutorial to learn how to use a scale. 1 oz= 28 grams.
