Weinstock began her professional career as an elementary school teacher on
Long Island. She began baking cakes for local restaurants and apprenticed with pastry chef George Keller at the suggestion of
André Soltner of
Lutèce. William Greenberg, a fellow bakery owner, began referring clients to her for wedding cakes. She preferred not to use
fondant, describing it as "cheap and easy."
Bon Appétit magazine dubbed her "the Leonardo da Vinci of wedding cakes." She also appeared in season 1 of the
Netflix series
Nailed It!, where she was described as the show's "secret weapon." She also taught cake decorating at the
Institute of Culinary Education. == Personal life ==
