Abstract: An apparatus for forming composite ice cream-like edible novelties having discrete doughy additions therein. The apparatus includes a main die having an entrance and an exit disposed downstream of the entrance and at least one intermediate die positioned within the main die at a location upstream of the exit of the main die. An ice cream-like composition is introduced to the entrance of the main die in at least a semi-frozen state. A doughy addition supply system is also included such that a stream splitter divides a single doughy addition stream into equal streams, each supplying the intermediate die with the doughy addition at an elevated temperature and at equal rates. The ice cream-like composition and the discrete doughy addition are extruded together through the exit of the main die to form the composite ice cream-like edible novelty.
