In a machine for manufacturing multi-layered decorative ice cream cake and pie products. The machine frame supports a plurality of ingredient dispensing stations including ice cream dispensing stations. A conveyor simultaneously conveys products between the respective stations for indexing and positioning the products. The ice cream dispensers are mounted on lift positioning devices for lowering and raising the ice cream dispensers between a raised standby position and a lowering dispensing position. Ice cream dispensing valves on the ice cream dispensers open and close between a valve open position for flow of ice cream through an ice cream dispensing head from a continuous pressurized source of ice cream and a valve closed position for blocking the dispensing flow of ice cream. An index timer actuates the conveyor to convey products between stations and index products at each station for a selected dwell period. Position timers associated with the lift positioning devices actuate the lift to establish dispensing position intervals. Valve timers associated with the respective ice cream dispenser valves establish valve open intervals. The index timer dwell period, dispensing position intervals, and valve open intervals are operatively related and individually controlled through control elements. A central ice cream command and control panel permits an operator to achieve individualized control over operating parameters.
