Zionist Aroma coffee reverse-engineered

I think I sort of managed to reverse-engineer the good coffee from the Aroma chain in Israel, or at least got it close enough for my own purposes:

150 ml hot espresso,
150 ml hot milk,
20-30 g chocolate, dissolved in that hot milk,
Whipped cream and cocoa powder to taste (that's the real cocoa powder, you infidels, and not any of those powdered cocoa drinks).

Hot ingredients go together, cream goes on top, cocoa goes on top of the cream.
