A flapjack in the UK is a traditional baked oat bar made from rolled oats, butter, sugar, and golden syrup. It is a chewy, sweet snack, often cut into squares or bars, and sometimes includes variations with fruit, nuts, or chocolate chips. This British flapjack is quite different from the American flapjack, which refers to a type of pancake. The British flapjack has a long history dating back to medieval England, evolving from flat cakes cooked on a griddle to the oat bars well-loved today.
