If your granola bars don't seem to be staying together when you cut them, you may have not boiled the mixture long enough...you want it to make it just past the softball stage. OR you made them too thin or you didn't pack them in tight enough. Stick them in the fridge for 20 minutes and that should help keep them together. {Be sure not to keep them in there too long or else they'll become super hard!} The next time you make them, try boiling for an extra 15 seconds or so.
