Dancing with the flavors of the tropics is simple when mangoes are on hand. This upside-down cake offers a dazzling showcase -- the ripe fruit nestles in a simple caramel, its golden hues and honeyed taste deepening as it bakes. Banana and rum add more tropical notes and help keep the cake moist, from first bite to last crumb. Martha made this recipe on episode 509 of Martha Bakes.
