Bánh bò

Bánh bò (literally "cow cake" or "crawl cake") is a sweet, chewy sponge cake from Vietnam. It is made from rice flour, water, sugar, and yeast, and has a honeycomb-like appearance (called rễ tre, literally "bamboo roots," in Vietnamese) 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.
