Flapjack

A flapjack is a baked bar, cooked in a flat oven tin and cut into squares or rectangles, made from rolled oats, fat (typically butter), brown sugar and usually golden syrup. The snack is similar to the North American granola bar. As well as being baked at home, they are widely available in shops, ready-packaged, often with extra ingredients such as chocolate, dried fruit such as glace cherries, nuts, yoghurt and toffee pieces or coatings, either as individual servings or full unsliced trayfuls. Some flapjacks may contain maple syrup. They are usually an alternative to a biscuit or cake, and textures range from soft and moist to dry and crisp. Because of the high levels of fat and calories in traditional recipes, some "diet" versions are available with lower fat and calorie content.
