British flapjacks are baked oat bars made primarily from rolled oats, butter, golden syrup, and sugar. They are formed into a large, flat rectangle, baked until lightly browned and caramelized, and then cut into small rectangles or squares. Unlike the American flapjack, which means pancake, British flapjacks are chewy oat bars often enjoyed as snacks or with tea, sometimes including additional ingredients like nuts, dried fruits, or chocolate chips. The treat has historic roots dating back several centuries in England and is considered a traditional and beloved baked good.
