This rich and moist matcha rare chocolate cake is made with white chocolate and honey. The flavor of matcha and the sweetness of white chocolate are perfectly matched, resulting in a smooth, melt-in-your-mouth texture. The ingredients are melted and mixed in a double boiler, and the emulsification of the matcha and sugars, which tend to separate, is carefully carried out to achieve a beautiful finish. After baking, chilling it in the refrigerator overnight allows the flavors to meld together and deepens even further. Serve with whipped cream, powdered sugar, cocoa powder, or mint to enjoy it as a stylish café dessert.
