Just keep layering until you get as much as you want, or you run out of Oreos or whipped cream! =) Then, you don't have to, but I crumble some Oreos on top. Like this:

I mean, don't leave it in there for days because it will go bad, but, you know 8 hours will make it DELISH! (Sorry Rachel Ray, I used one of your words!) But, if you don't have the time, a couple hours should suffice! =) I guess you could do overnight, too. When you cut into this baby, it'll look like this:
It is so good, I can't even explain. No matter what they say, Oreos are JUST AS GOOD as Famous Wafers! Enjoy!
