Bánh bò are traditional, coconut-flavored Vietnamese sponge cakes that are prepared with a light yeast-based batter. There are several varieties depending on the shape, ingredients, and the method of preparation, but all of them have a distinct, airy texture which is why they are occasionally known as honeycomb or beehive cakes.

Bánh bò cakes can be baked or steamed and tinted with various natural colorings, while their base is usually made with rice or tapioca flour. The name bò roughly translates to a cow or to crawl, but it is not clear how and why the cakes were given their current name.
