Disclosed is an aerated fat-based confectionery that, unlike a conventional shell-type or tapered shape, has a novel shape, that is, a cubic or rectangular parallelepiped shape having top, bottom, and side surfaces in contact with and perpendicularly to each other, or any shape such as an animal or flower shape having a given thickness, has a light texture and a sharp melt-in-the-mouth sensation, does not require alignment in packaging. The confectionery can be obtained by aerating a fat-based confectionery mass having a fat content of 30 to 60% by weight such as chocolate to a specific gravity of 0.5 to 1.0 and cutting the aerated mass with a heated wire so that the side surface is perpendicularly to the top and bottom surfaces.
