Frozen is best, they last longer,
but if it is a Mars bar or similar , before you go out in the cold, get the back of a knife and press grooves in at bite size distances, then when it freezes it will snap off easily even with a gloved hand to give a handy mouthful that you can suck until it is soft enough to chew.
