In Vietnamese, the term bánh translates loosely as "cake" or "bread", but refers to a wide variety of prepared foods that can easily be eaten by hands or chopsticks. With the addition of qualifying adjectives, bánh refers to a wide variety of sweet or savory, distinct cakes, buns, pastries, sandwiches, and other food items, which may be cooked by steaming, baking, frying, deep-frying, or boiling. Foods made from wheat flour or rice flour are generally called bánh, but the term may also refer to certain varieties of noodle and fish cake dishes, such as bánh canh and bánh hỏi.

Bánh bò is a sweet, chewy sponge cake from Vietnam. It is made from rice flour, water, sugar, and yeast, and has a honeycomb-like appearance on the inside due to the presence of numerous small air bubbles. Coconut milk is also usually a part of the batter, imparting a slight flavor and aroma of coconut. The cake is of Southern Chinese origin, although the Chinese version, called bái táng gāo, does not contain coconut milk. Bánh bò are generally eaten as a dessert, although they may also be consumed as an accompaniment to a meal.
