bonbon: [bahn bahn] noun
Also bon bon or bon-bon. 1. Any sort of candy or confection. 2. Confections that are chocolate-covered, but are not truffles, such as a buttercream or praline-filled chocolate. 3. Individual round portions of ice cream, dipped and covered in chocolate.
Bonbon is somewhat of an old-fashioned term and is not used that much anymore outside of the commercial confectionery industry.
