Maltesers' core ingredients include a crispy, airy honeycomb malted milk center made from barley malt extract, sugar, and milk, all enveloped in a smooth milk chocolate coating (sugar, cocoa butter, milk solids, cocoa mass, milk fat, emulsifiers like soya lecithin). Key components are sugar, skimmed milk powder, glucose syrup, barley malt extract, and vegetable fats (palm/palm kernel), plus raising agents (E341, E500, E501) for the centre and wheat flour/gluten.
