Chocolate cake is the greatest dessert ever. Since its discovery it has become one of the most popular desserts of all time, with good reason. It is a symbol of joy among all Americans and will stay that way forever. I realize that being a taste, the pure amazingness of this cake can't be described in words, so voting will be heavily swayed by personal taste. (Pun intended)
I do not believe chocolate cake to be the best merely because different people have different tastes. Chocolate cake may be one persons favorite, but it may not be the next persons favorite, so therefor it cannot be the "best desert".
