Cut the marzipan into small pieces. Mix cream, marzipan and orange peel with the whisk of the hand mixer to a creamy mixture.
Unroll the yeast dough. Spread marzipan mixture on top, sprinkle with raisins and about half of the almond slivers and cut into strips about 3 cm wide. Fold the strips lengthwise over the filling and place them spirally together in a greased springform pan sprinkled with flour from the outside inwards and press lightly.
Spread the rest of the almond slivers on top and bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for 25-35 minutes. Remove the cake from the oven and let it cool down on a cake rack.
Stir icing sugar and 4 tablespoons of water until smooth. Spread the icing over the cake and serve.
