Protein shake recipes?

I always need a protein shake before bed to help get in enough protein and calories into my day, and I have a delicious Rocky road flavored one right now, but I'm getting a bit bored with it right now. I have looked up recipes for protein powder, but they all have something like 2 scoops for an entire batch of cookies. Obviously, I don't want to eat 10 cookies just to get enough protein lol. Does anyone have any recipes for something (other than a shake, duh) that has a scoop per serving?
