A Manhattan woman is making a federal case out of white chocolate.

Aurora Morrison, 35, charges in a class-action lawsuit that Drizzilicious snacks do not contain the real McCoy as advertised on product labels.

Drizzilicious Cinnamon Swirl and Drizzilicious Birthday Cake are marketed as being “drizzled with white chocolate” or enhanced with “white chocolaty drizzle.”

Morrison says she relied on the packaging when she plunked down $3.69 for the Cinnamon Swirl mini rice cakes at her local Fairway Oct. 8, but the treat failed the tastebuds test. The “white chocolaty” product “did not deliver the qualities it promised,” the Manhattan federal court lawsuit says.

Morrison claims the rice cakes contained “inferior confectionery ingredients that are not white chocolate at all” and she wouldn’t have opened her wallet had she known the product “was mislabeled,” the complaint says.

The suit contends that because the products contain imitation white chocolate, consumers don’t get their money’s worth, noting “white chocolate specifies only one thing: a confection that contains cocoa butter, dairy ingredients and a sweetener.”

The lawsuit, which names Snack Innovations as defendant, seeks at least $5 million for alleged fraud and deceptive advertising. Morrison could not be reached for comment. Snack Innovations did not return messages.
