How to make
Mix together the eggs, sugar, yoghurt, oil and baking soda, add the flour to them at the end. Pour the mixture into an oiled form and sprinkle with flour.
Bake at 360°F (180 °C) for 30 minutes in a preheated oven.
For the glaze: Melt the 2 types of chocolate in a water bath with milk separately. Once the cake is baked and cooled, first pour on the milk chocolate and then the white chocolate (or vice versa).
