Clean, wash and cut rhubarb diagonally into pieces. Cut the fat into pieces. Grate 120 g marzipan. Cream the fat, 130 g sugar, vanillin and marzipan with the whisk of the hand mixer. Stir in the eggs one by one.
Mix 220 g flour, almonds and baking powder and stir in alternately with the cream. Fill 1/3 of the dough into a greased springform pan (26 cm Ø) sprinkled with flour. Add half of the rhubarb to the remaining dough and fill into the springform pan. Sprinkle the remaining rhubarb on the dough, sprinkle with 1 tablespoon of sugar. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 50-60 minutes. Mix 150 g marzipan, 1 tablespoon flour and egg white and fill into a piping bag with star-shaped spout. About 30 minutes before the end of the baking time, spray 9-12 S-shaped macaroon rings onto the cake. Take the cake out of the oven, remove from the edge and let it cool down on a cake rack. Dust the cake with icing sugar.
