Gotta Protein Bar Recipe?

There are a lot of resonably priced protein bars now. Quaker Q-Smart or Post Carbwell for example. I've decided to work on my own home made version to see if I can get more protein in with less cost. So, does anyone have a protein bar recipe? I haven't found a great one surfing the net yet. I'm working on my own but so far my efforts have been eatible but not very tasty. I baked a batch with Total protein cereal, peanut butter, eggs, splenda, protein powder, milk, and oatmeal. 300 calories, 23g protein, 23 carbs, 13 fat per serving. I've found it's easy to create something with 850 calories and 30g protein. Think a loaded rice krispy treat or corn flake peanut butter bar. It's hard keeping the calories down.
