It is a convenience food version of jjinppang (steamed bread) and is typically filled with smooth, sweetened red bean paste.

Hoppang is a product that makes it easy for the family to eat steamed bread, which was formerly sold at snack bars.

[2] Hoppang was a brand name for the ready-to-eat jjinppang developed by Samlip in 1970, which combined the onomatopoeia ho, ho (the sound for blowing on hot steamed bun) and ppang, the Korean word for bread.

Typical hoppang is filled with sweetened red bean paste,[4] but it is also commonly sold stuffed with vegetables and meat, pizza toppings, pumpkin, or buldak.

[1][5] Steamer- or microwave-ready hoppang is often packaged in multiples at supermarkets and grocery stores, while many convenience stores sell hoppang throughout the winter months in cylindrical heating cabinets designed to steam and keep them warm.
