Sylvia Weinstock, who took the art of baking to new heights with her 10-foot-tall wedding cakes and their garlands of hundreds, and sometimes thousands, of handpainted sugar flowers, died Nov. 22 at her home in Manhattan. She was 91.

Mrs. Weinstock was best known for her elaborate wedding cakes, with flowers cascading down over multiple tiers of buttercream frosting. But she also baked novelty cakes in the shape of cars or dogs or other beloved items for birthdays and other special occasions.

Her clientele included Whitney Houston, Ruth Bader Ginsburg, LeBron James, Robert De Niro, Oprah Winfrey, Martha Stewart, the Clintons, the Trumps, and various Kennedys and Kardashians.
