Ice cream maker Joseph

EDY

This 19th-century candy maker’s first name is hidden in "Dreyer’s" brand ice cream—look for the initials.

This clue refers to Joseph Edy, one of the founders of the Edy’s ice cream brand (now part of Dreyer’s). The answer is simply his last name, "EDY," which is short and fits neatly in crosswords. It’s a straightforward reference to a well-known name in frozen desserts, with no hidden wordplay or tricks.
