How to make
All ingredients need to be at room temperature. Whip the eggs and sugar with a whisk.
To 1/2 the yoghurt add the baking soda, add the eggs to the other 1/2, pour in a little oil and add vanilla. Add the flour in lots and stir. Bake in a glass cooking form at 280°F (140 °C) initially, then turn the heat up to 320°F (160 °C).
While the cake layer is cooling, make the topping. Put everything for it in a bowl and boil on the stove. Poke holes in the baked and cooled cake with a skewer. Distribute the topping over the entire baked cake layer with holes using a brush.
Make the white stripes. Mix the margarine with the powdered sugar and distribute it over the chocolate topping in lines. Make the actual stripes by dragging a wooden skewer across the lines.
