In a coating apparatus for applying a coating composition to substantially flat baked pieces, particularly cookies or the like, which apparatus includes a supply container (15) and a metering device (14) succeeding that container, it is proposed to provide between the supply container (15) and the metering device (14) a substantially horizontal screw conveyor (13), which serves to transpsort the coating composition to the metering device (14) and which at its discharge end opens into the metering device (14), which includes a cylindrical coating head (14) having a substantially horizontal longitudinal axis. The metering body of the coating head (14) consists of a cylindrical drum (21), which rotates about the longitudinal axis of the coating head (14). That drum (21) is provided with radial discharge nozzle passages (28). A pressure sensor (36) for controlling the velocity of conveyance of the screw conveyor (13) is provided in a stationary part of the coating head (14).
