Shadow Milk Cookie is a spindly, average height Cookie with powder blue dough and two differently colored eyes: one cyan right eye with a black slit pupil and black eyelashes, and one cerulean left eye with a white slit pupil and white eyelashes. His mouth is sapphire blue and sly, having teeth which change between straight and sharp depending on his emotions. About his right eye is a pale blue, claw-shaped marking. He has white locks of hair near his face—two that fall against his forehead and one slicked back—azure curled sidelocks, and glossy, sharp, long hair in a dual-toned shadow and lapis style that resembles the extents of a jester's hat.
