Twinkies are a popular snack cake made by Hostess Brands. They consist of a golden sponge cake filled with a sweet, creamy filling. Each cake is individually wrapped, making them convenient for on-the-go snacking. Originally introduced in 1930, Twinkies have become an iconic treat in American culture. They are known for their long shelf life, which is partly due to their preservatives. Over the years, Twinkies have inspired various flavors and limited-edition versions, but the classic vanilla cream filling remains the most beloved.
