Simple and stylish
The couple likes the comic figures "Rosalie und Trüffel" and had invitations etc. styled in in dark brown and pink. So the cake had to match as well but they wanted simple and stylish, not kitsch. This is what they got :-)
The photo unfortunately does not give an accurate impression of size. The difference of tier sizes is intentional, in reality the middle tier was better balanced, size wise.
Bottom tier is Walnut-Genoise with Chocolate IMBC and the 2 top tiers are Lemon-Buttermilk-Cake with Lemon-Curd filling.
