The bar is made from sugar, cocoa butter, whole milk powder, glucose syrup, an emulsifier (lecithins), and natural vanilla flavouring, with vegetable fats (such as palm, shea, mango kernel, or sal) included alongside cocoa butter to deliver Milkybar’s signature creamy texture. According to allergen guidance, the product contains milk, may contain gluten, and from July 1, 2024, carries a warning that it may contain nuts due to shared production facilities handling nut-containing products. The recipe itself contains milk as the first ingredient, with no artificial colours, flavours, or preservatives used in line with Milkybar’s simple, clean formulation.
