Milka chocolate, while not officially halal certified, does not contain any ingredients typically considered haram. Based on its listed ingredients—sugar, cocoa butter, skim milk, chocolate, whey, milkfat, hazelnut paste, soy lecithin, and artificial flavor—it appears to be halal. However, it is important to note that there is no formal halal certification from Milka or its parent company, Mondelez International.

And Allah knows best.
