Rice crispy treats are a popular no-bake dessert made from rice cereal, marshmallows, and butter. The marshmallows are melted and mixed with the butter, then combined with the cereal to create a sticky, sweet mixture. This mixture is pressed into a pan and allowed to cool, forming a solid, chewy treat. These treats are often cut into squares or rectangles for easy serving. They can be customized with additional ingredients like chocolate chips, sprinkles, or peanut butter, making them a versatile snack. Rice crispy treats are enjoyed by people of all ages and are commonly made for parties and celebrations.
