Maltesers are a confectionery product created in 1936 by Mars Incorporated. They consist of light, airy balls made of malted milk surrounded by chocolate. Maltesers come in a wide variety of packages and are most popular in the UK, Australia, and Ireland. While tasty, Maltesers can be enjoyed as part of a balanced diet. This year, Maltesers will start carrying the Fairtrade mark in the UK and Ireland.
