I must say Ondeh-Ondeh is definitely anytime my utmost favourite too with its bursting sweetness on a salted shredded coconut.
However I can't eat this all the time because this is too high in sugar which is not supposed to be good for me haha.
Once a blue moon, yeah when the craving goes beyond getting my lazy bum up to walk at least 500 steps to acquire it (if I am lucky), I'd do it.
Otherwise I only couldn't resist it when Bazaar Ramadan is up and the stalls selling these are everywhere
