A small plastic container containing several ounces of vanilla, chocolate, or tapioca pudding. Parents often send their children to elementary school with one of these and a plastic spoon in their lunch box. They make an excellent quick dessert treat, and are very satisfying.

For some time, Bill Cosby has done American commercials advertising Jell-O pudding products, even though Jell-O built their reputation making various gelatin products.
