Banh thuan, also known as banh thung in local pronunciation, originates from the Quang Nam – Binh Dinh region in Central Vietnam. According to historical documents and shares from locals, this cake appeared in ancient times, closely associated with rural life and Tet (Lunar New Year) holidays. The name "thuan" originates from the shape of the cake mold, which resembles a shield (thuan) in ancient times, cast in cast iron with oval or apricot blossom-shaped molds.

In Hoi An cuisine, Banh Thuan carries deep cultural significance. It symbolizes luck and prosperity because when baked, the cake blossoms like an apricot flower—a flower representing spring and wealth. The people of Quang Nam often make Banh Thuan to offer to ancestors or give to friends, expressing a simple and genuine heart. Not just a rustic treat, Banh Thuan also evokes childhood memories, attached to warm gatherings around the hearth. Compared to modern sponge cakes, Hoi An Banh Thuan preserves traditional values, using natural ingredients and contributing to preserving the UNESCO culinary heritage of Hoi An Ancient Town.
