A microwaveable confection mold for use in a conventional microwave oven. The mold permits solid confection capable of melting when exposed to microwave energy to be introduced into the mold. The mold comprises a clear microwave transparent plastic material to facilitate observation of the confection melting process with subsequent settling in the mold sections. A pigment in the mold changes the colour to indicate to the user when the liquified confection has hardened and the mold cooled.
