I am looking for a recipe of little cakes, steamed cooked, white,
coconut flavour, with a yellow heart vanillia taste i presume)...

I don't if this is what you are looking for:
Glutinous rice balls

Glutinous rice flour - 50 g / 2oz
warm water - 2 tbsp

filling: lotus seed paste or red been paste or vanilla custard - 25 g
/ 1 oz
coating: dessicated coconut - 25g / 1 oz

Mix first 2 ingredients until smooth, divide into 8 portions. Divide
filling also into 8 portions. Take a piece of dough, flatten it, wrap
a portion of filling in the centre and form into a ball. Steam on wax
paper for 10 minutes. Remove and roll in coconut. Let cool and serve.

I have not tried this recipe, the small amount of ingredients look
suspicious, but you get the general idea.
