I remember that post - can't seem to find it at the moment though.
The one I remember was natural peanut butter, mixed with oats (I used quaker porridge oats), whey & honey and, microwaved until a cake like consistency and then cut into bars, wrapped in foil and kept in the fridge. I would occasionally add egg whites if it seemed to be a bit crumbly.
Unfortunalely, it has been ages since I made them so, I can't really remember the specifics. If I come across the thread, I'll post it here.
