Separate eggs. Beat the egg whites and 3 tablespoons of cold water until very stiff. Finally, pour in the sugar. Carefully fold in the egg yolk. Sieve flour, baking powder, gingerbread spice, cocoa and starch onto the mixture and fold in carefully. Line a springform pan (18 cm Ø) with baking paper.
Fill in the sponge cake mixture and smooth it down. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 12-15 minutes. Remove the sponge cake from the oven, remove from the edge of the springform pan and let it cool down on a cake rack. In the meantime soak the gelatine. Mix cream cheese, cognac and honey. Roughly chop the chocolate. Crumble the gingerbread. Squeeze the gelatine and dissolve. Stir into the cream cheese mixture drop by drop. Whip 200 g cream until stiff, allowing a packet of vanillin sugar to trickle in. Fold the gingerbread, chocolate and whipped cream into the mixture. Cut the sponge cake in half horizontally.
