Banana roll or banana cake is a common Chinese pastry found in Hong Kong, and may occasionally be found in some overseas Chinatowns. The pastry is soft and made with glutinous rice.[1] Ingredients may vary depending on location. Each roll or cake is a banana oil flavored circular tube or flat object, slightly bigger than an adult sized index finger, thus resembling banana. Sometimes it may have a cinnamon swirl filling. At other times it may have a filling that consists of a very ripe banana diced finely. Occasionally the more traditional red bean paste may be used.
