Homemade Flapjack

Currently in the oven. Does anyone know how long they keep in an airtight container? or can I freeze them?

In my house they wouldn't last more than a day or so, but if you have more self control than me, I'd have thought they'd be good for a few weeks

Yes you can freeze them wrap in cling film individually and take out as many at a time as you want. They wouldn't last more than 3 days in this house my OHs favourite.
