Châteraisé has this Double Fantasy Cream Puffs (S$1.90) that features two fillings in a big pau sized cream puff -- Hokkaido cream and vanilla custard / matcha / chocolate.

While the fillings may not be as distinctly layered as shown on advertisements, the cream puff has got a pretty thin wall enveloping the fillings. Every mouthful does remind you that you are eating desserts (and possibly cream fats too), but yet the sweetness was managed just nice.

Even though the cream puffs are individually packed, they have a very short shelf life, so don't think of stocking this up even if you like its flavour and texture like I do.
