FIELD: food-processing industry.;SUBSTANCE: method involves producing desert from ice cream containing embedded decoration of ice cream laid in creases, said creases being laid in alternation in one direction and opposite direction. Decoration is performed using extrusion apparatus consisting of set of movable nozzles having flat tip and slot-type discharge opening. Nozzles are positioned above movable substrate. Nozzle unit is positioned above movable substrate and adapted for extrusion of sauce containing cold ice cream composition fed in the form of at least one extruded strip of ice cream composition having temperature of -6 C. Apparatus alternatively consists of support for set of movable nozzles. Vibrating motion is imparted to support in direction perpendicular to direction of movement of substrate. Apparatus is further equipped with mechanical means for driving of vibrating support.;EFFECT: increased efficiency of method and apparatus allowing continuous process for decoration of product with complicated decorations to be provided.;16 cl, 8 dwg
