I made this cake for my best friend's bridal shower. The cake inside is sponge cake with 6 eggs, 180g sugar, 100 g all purpose flour, 100g corn starch, 60g butter, 60 g milk. I separated egg white from egg yolks. Egg white was mixed with sugar then fold with the mixture of the rest. The "dress" was made by homemade fondant, which is made from mash mallow and powder sugar.
