Mixing and dispensing apparatus for a frozen confection machine for mixing and dispensing a measured volume of frozen confection material and a flavoring material including edible solids. The apparatus comprises a mixing and measuring chamber including a mixing cylinder having a discharge head at one end, a rotary mixer in the cylinder and a dispensing piston slidable in the cylinder. The mixing and measuring chamber has a flavoring material inlet port, a flavoring material feed chamber communicating with the flavoring material inlet port, and a flavoring material feed piston for feeding flavoring material from the feed chamber to the mixing cylinder. The mixing and measuring chamber also has confection material inlet port adapted for connection to a frozen confection machine and a confection inlet valve for controlling flow of confection to the mixing cylinder. The discharge head has a discharge passage and a discharge valve for controlling flow through the discharge passage. Operating mechanism is provided for moving the dispensing piston in the mixing cylinder to a position contiguous to the discharge head to discharge substantially all of the material from the chamber. Heat transfer apparatus is provided for cooling the mixing cylinder from the frozen confection machine.
