I made up a bunch while I was pregnant and put it in ziplocks in the fridge. I made it about a month maybe two before I was due and it kept fine and was so delicious I only regret not making more since it is now all gone. I would recommend not adding any dried fruits until you are ready to eat it as they might get really hard in the fridge.
Mine keeps fine for at least 2-3 weeks in glass jars in the cabinet. I haven't tried freezing it. I wonder if the texture would be ok, but maybe if there were an issue, a few minutes in the oven would crisp it up?
