Sadly all of the Hostess Brand "snack cakes" Twinkies, Ding Dongs, Sno Balls (you have the Halloween version of the Sno Ball) etc are, despite their extraordinarily long shelf life, an endangered species.
Business declined, there were labour issues, and now the company is bankrupt. Hostess and Wonder Bread were iconic brands, but were also the very definition of bad nutrition - the awareness of which led to declining sales.
