Simple Ice-Box Cake recipe w/ oreos?

So here's what I'm thinking. The simplest icebox cake recipe I've found calls for only 2 ingredients: Chocolate Wafer Cookies and cool whip. Now, the appeal of this recipe is it's simplicity! I am in college, so I don't really have a lot at my disposal. what I am asking is, am I correct in thinking that this simplistic form of icebox cake exists, i.e., is it just wishful thinking? and second, can I substitute oreo's without the frosting for the chocolate wafer cookies?
