Just grind it and use any recipe for pancakes, bread and biscuits. Its just flour.
Go to allrecipes.com search for pancakes find one with a ton of reviews that are good, then look at the comments. copy the recipe and you are set. Do the same for bread and biscuits. It will be whole wheat flour recipes.
For SHTF yes. But 3 cups of wheat flour will make a very dense loaf of bread. It will be tasty just dense. Most recipes calling for wheat flour mix it with white. You may have to increase your leavening to lighten it up (more yeast, baking powder, egg etc. )
I ground some whole wheat with my corn grinder, and made bread. The corn grinder does not make it fine enough to really call it flour. It was a tasty brick.
I would just buy some whole wheat flour and experiment.
