    • A dough extruder (10) has a die set (30) with an inner die (54) and an outer die (64). The inner die (54) is formed in a desired shape (61) that represents an item of interest, such as an animal, toy, or other identifiable object, and the outer die (64) has an opening surrounding the inner die (54). Dough is extruded through each of the dies (54, 64) simultaneously. The dough for the inner die (54) has different indicia, such as color or other visually identifiable characteristic, from the dough extruded through the outer die (64). A sizing housing (66) is positioned downstream from the dies (54, 64) and smoothly changes in cross-sectional size in direction away from the dies (54, 64) to permit the dough to flow such that streamlines remain parallel as the sizing housing (66) changes in size, to accurately retain the center cross-sectional shape of the extruded dough as formed by the inner die (54). Preferably, as disclosed, the sizing housing (66) is cone-shaped to reduce the extruded dough cross-sectional area.
