haven't made this recipe myself, but it's from a good eats episode that is specifically designed to make more health-conscious versions of things like protein/power bars. it's all natural.
just go to food tv's website, and type "granola bars" in the search window--it's the first to pop up. i'd link you myself, but this is my first post on the board and my hands are shackled!
alternately, he also has a very simple granola recipe using maple syrup (not a soft bar--much crunchier) you can easily find by doing a search on that site.
