Wagon Wheels are a sweet snack food sold in the United Kingdom, Australia, Canada, other Commonwealth countries like New Zealand and India, and also in the Republic of Ireland (which is not a part of the Commonwealth). They consist of two biscuits that form a sandwich with a marshmallow filling, and they are covered with a chocolate-flavoured coating. 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.
