People don't expect light desserts at The Cheesecake Factory. But the Chocolate Tower Truffle Cake kicks things up a notch. If it weren't served on its side, this one would stand over six inches tall. And upright or not, the slab of cake still weighs in at three-quarters of a pound. What do you get for all that heft? Just 1,670 calories and 2½ days' worth of saturated fat (48 grams), nearly all of it from chocolate, sugar, cream, white flour, and butter.
