In the US, we often use u0022flapjacksu0022 and u0022pancakesu0022 interchangeably. A flapjack might just be a more rustic version of a pancake, but on restaurant menus you'll see both terms for the same dish! But in the UK, flapjacks are nothing like a pancake. British flapjacks are more like an oat granola bar, which are cooked in a pan and then baked in the oven. Traditionally, British flapjack recipes have oats, butter, brown sugar, and syrup. My version is obviously much healthier than that, but keeps the spirit of the traditional version!
