White Choco

You must have been taken aback by the overwhelmingly strong sweetness instead of the expected soft and sweet taste. The cake you had at Tous Les Jours is likely a recently renewed product, a Lotus collaboration item, or a new product from the fall/winter season. White chocolate itself is naturally sweeter than regular milk or dark chocolate due to higher milk powder and sugar content. This sweetness seems to have been amplified by the addition of crushed Lotus cookie bits. Lotus cookies have a distinct cinnamon aroma and a strong sugary syrup flavor, which can make the cake taste overwhelmingly sweet, almost numbing your tongue when combined with the cake layers or cream.
