"sweet cake, tart," 1748, from German Torte; earlier sense of "round cake, round bread" (1550s) is from Middle French torte; both are from Late Latin torta "flat cake," also "round loaf of bread" (also source of Italian torte, Spanish torta), probably related to tart (n.1). Not considered to be from the source of tort.
