Cream fat, 300 g sugar and salt with the whisk of the hand mixer. Stir in the eggs one by one, stirring each time until the mixture is bound
Mix the flour and baking powder, alternating with 275 ml milk in 2 portions. Stir in 2 tablespoons of liqueur at the end. Mix half of the dough with cocoa and 75 ml milk. Alternate doughs with a tablespoon always in the middle (on the same spot) in a greased springform pan (26 cm Ø) sprinkled with flour. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for about 50 minutes. Let the cake cool down a little on a cake rack
Soak gelatine in cold water. Remove the base from the springform pan and cut through halfway along the rim. Spread the bottom cake layer with 3 tbsp. jelly and enclose with a cake ring
Mix quark, 2 tablespoons of liqueur, 75 g sugar and vanillin sugar. Whip cream until stiff. Squeeze the gelatine, dissolve and mix with 4 tbsp. quark, then stir into the remaining quark. Fold in cream. Smooth the cream on the base. Place the cake lid on the cream and press down gently. Chill for approx. 4 hours
Remove the cake ring and coat the cake with the remaining jelly. Knead marzipan with icing sugar and a little food colouring. Roll out 400 g marzipan on a worktop dusted with icing sugar to form a circle (45 cm Ø). Cover the cake with it and cut off the protruding edges. Knead the rest with the remaining marzipan and divide into 5 equal pieces. Roll each piece of marzipan into a long roll (approx. 30 cm long). Roll out rolls to approx. 4 x 50 cm. Spread the cake with water. Loosely twist each strip of marzipan into a snail, lay it carefully on the cake so that roses appear and press it down gently
