Also called: cereal bar, muesli bar

Flapjacks are made by melting butter, brown sugar and golden syrup together, stirring in rolled oats, pressing the mixture into a lined pan and baking until golden at the edges. They are cut into squares or fingers while still slightly warm and firm up as they cool.

The texture can be chewy or crisp depending on baking time. Common additions include dried fruit, nuts, seeds and a chocolate topping. Flapjacks are a lunchbox and bake-sale staple in the United Kingdom. In North America, the same word usually means a pancake, so the British bar is often called an oat bar there.
