It's easy to make a great British flapjack in 35 minutes. This traditional favorite is at home on the tea table or in a lunch box or picnic basket. The snack is inexpensive, delicious to eat, and easy to customize using your own additional ingredients.

In the U.S., a flapjack is a thick pancake, but this flapjack is a tray bake (similar to a bar cookie). It's not unlike a homemade granola bar, packed with whole-grain oats and sweetened with golden syrup.

Although there is sugar in the flapjack, it also can be considered healthier than many other cake bars. The main ingredient in a flapjack is oats, which are full of iron, zinc, and vitamin B, so you can eat them without too much guilt.
