The history of the flapjack or flap-jack takes us back to the early 1500s although in those days it may have been a turnover or fruit tart folded. Hence the derivated name coming from the word fold. There is an old recipe called the Sussex Flapjack which is a sort of apple turnover.

They must have been popular way back in time as Shakespeare even mentions flapjacks in Pericles, Prince of Tyre.

Come, thou shant go home, and we’ll have flesh for holidays, fish for fasting-days, and moreo’er puddings and flap-jacks, and thou shalt be welcome

William Shakespeare – Pericles, Prince of tyre (act II, Scene i)

In fact a flapjack was more of a fruit turnover or fruit tart all the way up until the early 20th century. Then this was taken over by what we Brits know as the good old oaty flapjack we see today. Made originally for using leftovers of oats, butter, sugar and syrup.

In USA the word flapjack is sometimes used as the name for a pancake. And in other countries like Australia what we call a flapjack, could be known as an an oat slice. Cereal bar or oat bar are used too in some English speaking countries.

If this, the basic recipe is a little too plain for you, why not spice it up a little by adding a teaspoon of cinnamon or by throwing a handful of chopped mixed nuts, fruit, or chocolate drops into the oat mixture.
