A British flapjack is a traditional oat bar made from rolled oats, butter, sugar, and golden syrup, baked in a flat tray until golden and chewy, and then cut into squares or rectangles. It is a sweet, chewy oat snack bar, often enjoyed as a teatime treat or snack, and sometimes enhanced with fruit, nuts, or chocolate chips. Unlike the American usage where "flapjack" means a pancake, the British flapjack is more like a homemade granola or cereal bar. The name "flapjack" has origins dating back to medieval England, initially referring to flat cakes cooked on a griddle, but evolved over centuries to mean this oat-based baked bar popular in the UK today.
