protein bar recipes?

Hello everyone..
So, I've been trying to incorporate protein into my diet (aside from dairy/meat). Just recently, I tried special K protein meal bars and i love them..
but A. they're expensive (and i'm a broke-*kitten* college kid) and
B. i feel these could be homemade without the added sugar/fat.

(I know they're kind of a "glorified cookie" but i enjoy indulging myself with a well-earned sweet treat, everyday.. and it's nice when such a thing has a bit of nutritious goodness to it)

Has anyone tried homemade protein bars? I'm thinking of concocting something similar to the special k bar when i get back home for the summer.. when i finally have time to bake/cook!!

I'm up to the challenge of creating a recipe, on my own, but if anyone has a recipe or two (or more!) to share, that would be awesome and much appreciated!
Also, I'm interested in any granola bar/healthy "cookie" recipes, as well.


Thanks for your help!!
