I have not tried this but am willing to bet it would turn out pretty good. I have been on a kick making my own breakfast bar/ protein bars starting with a 2 cups of oats, 2-21/2 cups of powdered milk, 1/2 -1 cup soy protein, 1/2 -1 cup sugar,white or brown. Mix it all in a bowl , then bring to a boil 1/2 cup of water , 3 table spoons of honey and a box of unflavored gelatin. pour liguid over oats etc and mix well add more water if needed. Thats the basic recipe, I add chopped peanuts and peanut butter .Bake at 350 for 15-20 min. You could add spent grains to this to change up the flavor. You could also use flavored gelatins and add dried fruits, rasins, dried cranberry, blueberry, dried apples or what ever. might be worth a try.
