How to make
Extinguish the baking soda in yoghurt and pour it into a bowl. Add the sugar and stir until dissolved. Add the oil under continuous stirring, and then the flour. Finally, add the grated chocolate wafers.
Put the mixture into a buttered and floured baking tray and bake at 360°F (180 °C) in a preheated oven for about 45 minutes. Readiness is checked with a stick.
The baked pie with wafers is to be removed immediately and smeared with oil. If desired, sprinkle with 2 grated wafers.
