The present invention concerns a process for producing a chilled dessert itemcontaining a crunchy composition arranged in superimposed layers in its mass,comprising the following steps: a helical ribbon of milk, cereal-based, vegetable-basedor fruit-based, product is continuously metered through a milk, cereal-based,vegetable-based or fruit- based, product outlet orifice of a metering nozzlea layer of molten substance intended to form the crunchy composition after coolingis applied, to the helical ribbon being formed, continuously from the beginningof it being formed to the end of it being metered, by metering through at least onemolten substance outlet orifice of said metering nozzle and the helical layerof molten substance thus being formed is trapped between the first ribbon of milk,cereal-based, vegetable-based or fruit-based, product and a second helicalribbon of milk, cereal-based, vegetable-based or fruit-based, product, byconcomitantly and continuously metering the second ribbon of product througha second product outlet orifice of the metering nozzle, such that said secondribbon is deposited onto the helical layer of molten substance being formed,simultaneously with the molten substance coming into contact with the firsthelical ribbon being formed.
