What is a Flapjack?

If you’re reading this from across the pond in the US, you’d be forgiven for thinking we’re talking about pancakes. But here in the UK, a flapjack is a chewy, sweet bar made from rolled oats, butter, golden syrup, and brown sugar.  

It’s a versatile, satisfying, and delicious treat that can be customised in a range of ways. You can add in any inclusions you like, from chocolate chips and fudge pieces to blueberries and freeze dried apple. Swirl in any spread or jam, flavour with spices, and even drizzle or top with a layer of chocolate!

The History of the Humble Flapjack

Flapjacks have been around for hundreds of years. They were first mentioned in Pericles, Prince of Tyre by Shakespeare, in the early 17th century. The word is thought to be a portmanteau of two old English words: 

  • Flap – to toss or flip (like a pancake) 
  • Jack – a common name, also an object or thing 

Back then, they more closely resembled the modern-day pancake: sweet, flat cakes made from oats and cooked on a ‘bakestone’ or griddle. The flapjack we know today didn’t come into being until the 1930s. 

How to Make Flapjacks

There are a million flapjack recipes on the internet, but for an easy, simple and traditional flapjack, all you need to do is heat the golden syrup, sugar and butter together until the sugar is dissolved and the butter has melted, then stir in the rolled oats and bake. You can even pop them in the air fryer until they’re golden!  

If you’re wanting a healthier version of a flapjack, you can swap the golden syrup for maple syrup or honey, or a mashed banana, or add in protein powder, nuts, seeds and dried fruit. You can even make this classic British treat gluten free and vegan by using gluten free oats and vegan butter! 

Prefer a no bake sweet treat? Add in your choice of nut butter for flapjacks that will set perfectly in the fridge. We love peanut butter and chocolate chips, or almond butter and raisins.
