The chocolate-coated marshmallow confections seem to have similar names all across Germanic Europe - negerzoenen in NL (and presumably in Flanders?), Negerküsse in Germany, Austria, and Switzerland. 'Neger' is closer to 'negro' than to the other epithet, so not quite as offensive; but enough that most or all of the manufacturers have changed the name (to 'Shokoküsse' or the like.) One alternative name is 'Mohrenkopf/moorkop', which means 'Moor's head's; again, I'm not sure whether they are still manufactured as such.
