White sugar sponge cake also called white sugar cake and white sugar pastry is a type of Chinese pastry. It is one of the most common pastries in Hong Kong. Overseas, however, it is much more rare in Chinatown bakery shops.
It is made from rice flour, white sugar, water, and a leavening agent.
While it is called a "cake", it is not served as a circular round cake. It is usually purchased as an individual square piece or a mini triangle. The cake is white in color. The consistency is spongy and soft.
