A process for manufacturing frozen aerated confectionery products is provided, the process comprising providing two rollers wherein each roller has a multiplicity of open cavities on its surface and wherein the rollers are aligned so that the surfaces touch providing filling means for filling said cavities with a frozen aerated confection at a temperature higher than the temperature of the rollers filling two cavities, one on each roller, with a frozen aerated confection having an overrun of between 10% and 130% allowing the frozen aerated confection to expand outside its cavity and counter-rotating the rollers so that respective cavities in the two rollers lie opposite one another and the frozen aerated confection in a cavity of the first roller is pressed against the frozen aerated confection in an opposite cavity of the second roller characterised in that the surfaces of the rollers in which the cavities are located are conical. An apparatus for operating the process is also provided.
