Luscious Four-Layer Pumpkin Cake

I have to wait over a month to eat this cake! It's being made for my birthday on October 29 and that's SOOOO far away! I'm seriously considering making it myself... maybe.... tomorrow! No one would have to know! 5760. That's how many calories are in the entire cake. I'm getting hungry just thinking about it. Torturous!
