A Twinkie is a "Golden Sponge Cake with Creamy Filling" created by Hostess, and baked by Continental Baking Co, which is owned by Kansas City-based Interstate Bakeries Corporation. The Twinkie was invented on April 6, 1930. Twinkies originally contained a banana filling, but this was replaced with a vanilla filling during the great banana shortage of World War II.
Twinkies are oblong in shape, approximately 4" x 1" (10 cm x 2.5 cm), and marketed in packages of two. They have a shelf life of 25 days - unusually long for baked goods - due to their lack of dairy based ingredients. Various urban legends have stated that Twinkies have shelf lives anywhere from several years up to one century in duration, but there is no evidence to support this. The Twinkie is often derided by unattributed critics as the quintessential junk food. 500 million are produced each year.
In 2002, the Arkansas State Fair introduced the fried Twinkie.
The shortened form of the word twinkie, twink is commonly used slang. In its most common use, in gay circles, it is used for a young, slender, clean-cut man/boy. Far less commonly, the term twinkie might be used disparagingly for an Asian-American who emulates Caucasians (yellow on the outside and white on the inside).
Twinkies originally contained a bananacream filling, but this was replaced with a vanillacream filling during a banana shortage caused by the outbreak of World War II.
