Bananas are the star ingredient in this classic Vietnamese dessert which can be steamed (hấp) or baked (nướng). It usually consists of sliced bananas and a creamy combination of condensed milk, sugar, coconut milk, and optionally bread, eggs, or shredded coconut.

Depending on the ingredients and the cooking procedure, the cakes can vary in shape and texture, while other varieties come in a form of banana fritters or incorporate additional ingredients and flavorings. Steamed versions are often served sprinkled with sesame seeds and doused in coconut milk.
