                                At over 6,000 calories for a single four-pound confection, Crumbs Bakeshop's viral 'Colossal' is considered to be the highest calorie cupcake on the market. This enormous treat isn't for a single serving, but its decadent ingredients and sheer size put it in a league of its own for indulgent desserts.
