Turn up your nose at Dunkin' Donuts and pass on the Krispy Kremes. Since 1953 the Vineyard Foodshop, aka Humphreys, in North Tisbury on Martha's Vineyard has been knocking out batches of addictive Bavarian cream doughnuts so large they're called Belly Bombs. Besides their mutant size, what makes these Herculean treats worth lining up for is an ample filling and, instead of anemic chocolate glaze, nearly an inch of chocolate cake frosting. Wrap your head and mouth around that.
