This easy traditional flapjack recipe comes with added crunch, satisfying the growling tummy monster and keeping him quiet until teatime. It’s also dead easy to make, takes moments and is absolutely delicious so when I returned from a rare weekend away to find the cupboards bare of after school snack food it was this recipe I turned to. My children are like locusts and can clear an area of food at an alarming rate so it’s very handy to have a few simple, speedy recipes up my sleeve, this is probably my favourite!

easy traditional flapjack recipe

I’ve been making this easy traditional flapjack ever since my lot were tiny tots, it is the added handful of cornflakes which makes them extra special – you can swap them for bran flakes if you want to and you can add in dried fruit for a bit of extra oomph but sometimes, at the end of a fractious day only the old recipes hit the spot; unadulterated, just as we remember them. The comfort of familiarity is hard to beat and when my children are feeling a bit put upon, when the day at school has just been a bit much it it this traditional flapjack that they ask for – who am I to refuse?
