Nilla is a brand name owned by Nabisco that is most closely associated with its line of vanilla-flavored, wafer-style cookies. The name is a shortened version of vanilla, the flavor profile common to all Nilla-branded products. Originally sold as Nabisco Vanilla Wafers, the product's name was changed in 1967 to the abbreviated form Nilla Wafer.
The original Nilla product is the Nilla wafer, a round, thin, light wafer cookie made with flour, sugar, shortening, and eggs. Originally flavored with real vanilla, Nilla wafers have been primarily flavored with synthetic vanillin since at least 1994, a change which prompted some criticism. Presently, Nilla wafers are described as having "natural and artificial flavor", according to the ingredients list on the box.
Nilla also produces a variety of spin-off products, including pie crusts. The crusts were first introduced in 1992 alongside pie crusts flavored like two other Nabisco cookie brands, Oreos and Honey Grahams.
