Melt 4 tablespoons of sugar in a pan until it is golden brown. Add cinnamon and stir in. Pour caramel on a piece of baking paper and let it cool down. Peel, quarter, core and cut apples into large pieces. Sprinkle with lemon juice and set aside. Mix the soft fat, 250 g sugar and salt with the whisk of the hand mixer until thick and creamy.
Stir in the eggs one by one. Mix flour, starch and baking powder. Alternately stir in with the milk. Grease a ring cake tin (2.5 litres capacity) and dust with flour. Crumble the caramel. Fold caramel and apples into the dough. Fill the dough into the ring cake tin and smooth it down. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 55-65 minutes. Take the cake out of the oven and let it rest for 10 minutes. Turn the cake out of the tin and let it cool down on a cake rack. Coarsely chop the dark chocolate coating and melt on a warm water bath. Cover the cake with dark chocolate coating and allow to dry (approx. 30 minutes).
