Around my house they won't last longer than an hour, but...Does anyone know how long you can store cake balls that are dipped in white or milk chocolate flavored almond bark? Would they keep longer in the fridge or an air tight container? etc.

I would think if you are planning ahead and keeping for only a couple days, an air tight container in the fridge should be fine. I think for longer or even a couple days really, air tight container in the freezer would work too. I mean, they are tiny buggers so they can't take that long to thaw!
