We have a double hit of lemon in these zesty lemon flapjacks. The zest of one large lemon and a generous helping of lemon curd. Depending on the lemon curd you use will depend on its sharpness or even its richness. As every brand has its own unique flavour. I have made these with both a supermarket own brand and a fancy pants expensive brand. And both were delicious.

These flapjacks also taste great if you don’t have a lemon on hand and need to forego the lemon zest. The lemon flavour is not as fresh but it still packs a punch from the lemon curd


I have mentioned on this site before the differences in American and British sayings. And this is another saying that has a difference. In the UK we call these kinds of bars flapjacks while in America the closest thing is granola bars or oat bars. From what I understand flapjacks in America are more along the lines of pancakes. But regardless of name, trust me when I say these zesty lemon flapjacks are super tasty.

Because I am a Brit, I will continue to call them flapjacks. Old habits die hard and I have been calling them flapjacks from childhood. I believe one major difference between flapjacks and granola bars is the addition of golden syrup. This is a British institution and I have used it many times already in recipes on this site. It’s a thick sweet gloopy sugar liquid that is golden in colour. If you are finding it hard to come by then honey can be used in its place as can light corn syrup. But it will alter the flavour profile, especially light corn syrup as it is not as sweet or flavourful as golden syrup.
