There is disclosed a process and apparatus for carrying out the process of producing expanded confectionery articles in which a confectionery formulation containing water in an amount sufficient to expand the formulation on heating under vacuum is formed into shaped pieces, located on a permeable support and heated under vacuum in an oven. Flushing gas or air is preferably bled into the vacuum in the oven so as to sweep vaporisable material out of the oven. Novel rounded and spherical expanded confectionery products are produced without the need for a vibratory shaping step.
