Put yoghurt in a bowl. Wash out 1 yoghurt cup, dry well. Add eggs, lime juice, up to 2 tablespoons, lime zest, up to 1/2 teaspoon, sugar, vanillin sugar and oil to the yoghurt. Mix with the whisk of the hand mixer. Mix flour and baking powder and stir in portions.
Pour the dough into a greased, flour-spread ring cake tin (2.5 litres capacity), smooth it down. Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 1 1/4 hours (test with sticks!). Cover the cake if necessary after half the baking time. Leave to rest in the pan for 10 minutes, turn out onto a cake rack. Let it cool down. Mix icing sugar and 1-2 tablespoons lime juice to a smooth glaze. Cover the cake with it. Leave to dry. Decorate with lime zest.
