Here at Sugar HQ we're crazy about Kara's Cupcakes, but it seems everyone has their preferred cupcake supplier. From Sprinkles, Crumbs, and Magnolia to the smaller businesses that bake up delicious minicakes with fluffy icing, stores that profit from a cupcake craze have popped up like frozen yogurt shops over the past few years.

Their appearance has become so noticeable that one economic writer wonders if cupcakeries are the bulk of a bubble that's waiting to pop; he questions the durability of the boom, the relative expense of cupcakes, and fears it's a reactionary trend without staying power. What do you think — is there a cupcake bubble?
