Homemade muesli bars

[pacinofan]

Hello, am wondering if anybody has ever had any success making muesli bars? I've been inspired by A Worrall-Thompson's in a copy of the BBC Good Food magazine but the recipe didn't work and the muesli bars are kind of muesli 'clumps' not really sticking together. Very tasty though!

Anyway, not to be deterred I want to do them again if anyone has any suggestions please? Thought these might be good for dd when we're out and about.

TIA,
