I ran across this survival bar recipe that is straight forward and uses ingredients you already have in your food storage. I like the idea of adding them to a car kit or grab-n-go kit. At a 1000 calories a bar, I might make four smaller bars instead of the two mentioned. I can see myself polishing off 5-10,000 calories if these were the only items available in my kits.

I would make sure to dry them well. A dehydrator might be a better option. I would also use a food saver vacuum bag system, if available.
Emergency Survival Bar
3 c. cereal (oatmeal, cornmeal, or wheat flakes)
2 1/2 c. powdered milk
1 c. sugar
3 Tbs. honey
3 Tbs. water
1/2 c. Jell-O (optional)
1/4 tsp. salt
Place all dry ingredients except Jell-O in a bowl. Bring water, honey, and Jell-O to a boil. Add to dry ingredients. Mix well. Add water a little at a time until mixture is just moist enough to mold. Place in a small square dish and dry in the oven under very low heat. Wrap and store. This will make 2 bars, each containing approx. 1000 calories or enough food for one day. These will store for a long time and are excellent for emergency packs, etc.
Eat dry or cooked in about 3/4 c. water.
