A snack consideration you might think about when hiking and refueling at the same time before you stop for a real meal might be cereal, packed in cup sized portions in a zip lock baggy. It's light, won't melt, and some high in carbs like Grape Nuts, give you a bit of an energy boost. My favorite is chocolate Cheerios, and/or Kellogs puffed oats. Just sayin'.
