Abstract: It is disclosed a container for storing muffins and for their serving. The container includes a bottom, a cover attachable to the bottom, and doors connected to the cover. In a closed state, the door defines together with the bottom and with the cover a sealed compartment for storing the muffins, which are disposed in dishes. In an opened state, most of the stored cakes are accessible for being taken out of the compartment. The dishes have several cake concavities of substantially uniform shape. The bottom may be a baking dish of six or more concavities. The cover includes a handle for carrying the container. The cover is locked to the bottom, and the door is locked to the cover. The container may have an oval or round shape. In a round container, the door is slidably connected to the cover.
