The design of a cake box usually consists of a rectangular or square-shaped base with sides that fold up to form walls around the cake. The box may have a hinged or removable lid that allows for easy access to the cake while keeping it secure during transportation.

Cake boxes often feature a simple yet sturdy construction to protect the cake from damage and maintain its freshness. Some may also include inserts or dividers to prevent the cake from sliding around inside the box.

In terms of aesthetics, cake boxes may come in a variety of colors, patterns, and designs to suit different occasions and preferences. They may also feature windows or clear panels to showcase the cake and enhance its presentation.
