Flapjack 

In the USA, a term used to describe an oat based pancake, sometimes eaten at breakfast.

In the UK, or at least in England, a term used to describe what American's call a granola bar. A snack made from oats, sugar or honey or golden syrup (treacle) and butter, occasionally with nuts or dried fruit added. When shop bought, they tend to be more rectangular in shape, but when homemade they tend to be cut in to square slices.
