cobbler n.2
"deep-dish fruit pie with thick, scone-like crust," 1859, American English, perhaps related to 14c. cobeler "wooden bowl or dish," which is of uncertain origin, or perhaps its shape simply reminded people of a cobblestone. Earlier cobbler was the name of a summer long drink made from wine or liqueur, crushed ice, and fruit slices (1809, in Washington Irving), which is sometimes said to be a shortening of cobbler's punch, but that term is not attested until 1847.
