Wagon Wheels are a sweet snack food sold in the United Kingdom, Australia, Canada, other Commonwealth countries like New Zealand and India. They consist of two biscuits that form a sandwich with a marshmallow filling with jam, and they are covered with a chocolate-flavoured coating.
Wagon Wheels were invented by William Peschardt, who sold the patent to Garry Weston, son of W. Garfield Weston. Garry Weston worked for his father's business in Australia before taking over his family's business in Sheffield, England. He placed two Marie biscuits around a marshmallow filling and covered it with chocolate. They were introduced in 1948. The name (originally "Weston Wagon Wheels") relates to the shape of the biscuits and capitalised on the Wild West, which was popular in mass media at the time.
