I have just made Jamie Oliver's fruity flapjack from the Comin Relief cookbook. Everytime I make it I follow the recipe (have done lots of different ones from different books) but it doesn't end up in nice rectangle pieces which are firm enough to stay together but soft enough for the kids to eat. I really want to get this right so the kids can have them in their packed lunch and it is annoying at the waste of time. They have just gone in the oven so what do I do when they come out as that is the bit that seems to go wrong? TIA.
