with or without explanation, as needed.

The emphasis is on "without marshmallow) and the fact that other, very similar products (especially Krembo) are probably just a tiny bit different (with Krembo, it could be the base and the fact that the inside is either vanilla or chocolate flavored which is not the case with chocolate kisses).
The other term, translated to "Moor's head" is for example not used in French speaking Switzerland, where they call them
Têtes Choco ("chocolate heads"). See wikipedia link below.

The inside of the chocolate kiss is "sweetened (normally sugar) egg white foam (whipped egg whites) and NOT marshmallows. The consistency is quite fluffy and not sticky or gooey (also see wikipedia link below).
There is probably no real equivalent product in the English speaking world.

The very similar "Schwedenbomben" (Swedish Bombs) in Austria are described as:
http://www.international-chocolates.com/2008/11/30/schwedenb...
Schwedenbomben are creations from Austria, and consist of glair foam and a filmy covering of bitter chocolate with and without coco crumbles. A legend tells that this kind of candy speciality was invented 90 years ago.
---------------------------
That glair foam is sweetened, beaten/whipped egg whites, very fluffy.

Schokokuss / Mohrenkopf / Negerkuss (without marshmallow)
German Schokokuss

Schokoküsse were first introduced in industrial numbers in 1920, although the first mention of them in Germany dates back to 1829. The sweets are sold all year long. Every year approximately one billion are sold.[citation needed] This makes an average of about one dozen per person per year. They are available in supermarkets, many bakeries and some schools. Sometimes they are sold pressed between two halves of a bun, which is also referred to as a Matschbrötchen ("Squished Bread Roll").[26]

These sweets are made of sweetened (normally sugar) egg white foam and not marshmallows. The consistency is quite fluffy and not sticky or gooey.

They were first only known under the names Mohrenkopf ("Moor's Head") or Negerkuss ("Negro's Kiss"), but most companies changed the official product-name in the 1980s[citation needed] to the more neutral Schokokuss ("Chocolate Kiss"), Schaumkuss ("Foam Kiss") or to brand-specific names (the most famous brand being Dickmann's). In the South and the West of Germany they are still commonly known as Mohrenkopf. In Austria they are referred to as Schwedenbomben ("Swedish bombs").

regarding: with or without explanation:
I meant that you can add an explanation for Schokokuss (chocolate kiss) if there is room or reason for it in your translated text.
Of course, I am explaining the Schokokuss in my answer above. Just to clarify.

another clarification: I suggest if Schokokuss is used, then one should at least put "chocolate kiss" in parentheses if no other description is needed.

I found this on dict.leo.org but in German, we usually don't refer to them as "Kuchen".

for a description, this could possibly do:

afterthought: I take back the "meringue" idea - that is a different consistency and not what is in a Schokokuss.
