A bento cake is a mini cake that is usually no bigger than three to four inches in diameter and is designed for just one person. It is a type of lunchbox cake that originated in Japan in the 12th century. The idea behind bento cakes is to take the concept of an individually-sized lunch and apply it to cake. Bento cakes are perfect for individual serving and are easy to store and transport. They are usually composed of layers of cake sandwiched together with icing, such as whipped cream, cream cheese, or buttercream. The cakes can be made in a variety of flavors and can be used to celebrate any occasion, including birthdays, holidays, weddings, and even gender reveals. Bento cakes are packaged in clamshell takeout containers, surrounded by parchment paper, and are usually eaten right out of the container. They are easy to make and are the cutest size, making them perfect for a fun surprise for a friend or family member.
