What is a bento cake?

A bento cake is a traditional Japanese dessert made with layers of sponge cake, fruit, and sometimes cream or custard filling. It is similar in appearance to a regular layered cake but is typically smaller and more compact, resembling a bento box. Bento cakes are often decorated with fresh fruit, chocolate, or decorative designs on top. They are a popular choice for special occasions and celebrations in Japan. The name "bento cake" comes from the resemblance of the dessert to a bento box, a traditional Japanese lunchbox.
