I'm thinking about the milky caffeinated dumplings (edit) @Force_majeure123 was dreaming of.

I have zero energy, lactose intolerance and my stomach is being a massive jerk so I can also only dream. But I found a coffee pastry cream recipe. You could probably stir some condensed milk in there too for a Vietnamese coffee sort of taste.

I was thinking the thin slippery unleavened dumpling skins might not go well unless you wanted to fake it with mochi or use one intended for sweet buns. I wondered about sweetening a pork bun dough recipe and making it like bao.

Then I found out Cantonese custard buns exist. Perhaps if you cooked the pastry cream down thick enough or added coffee to the intended custard filling it might work. It doesn't look quite creamy though. These are more complicated but look runnier.

Actually... the supermarket used to sell tubes of coffee flavoured condensed milk. You could put the flat dough skins in muffin trays to hold up the edges against spillage, squeeze it into the centre and quickly wrap it inside. I can't see the coffee tubes at Woolies or Coles but there are still tins you can spoon it out of... unfortunately the brand is Nestle.

Or chocolate steamed buns with white chocolate for the ganache.
