Rice Krispies is a breakfast cereal produced by WK Kellogg Co for the United States, Canadian, and Caribbean markets and by Kellanova for the rest of the world. Rice Krispies are made of crisped rice. When milk is added to the cereal the rice tends to collapse, creating the characteristic "snap, crackle and pop" sounds.

Breakfast cereal is a breakfast food made from processed cereal grains. It is traditionally eaten as part of breakfast, or a snack food, primarily in Western societies.
