How to make
Mix the egg with the sugar to a smooth cream, add the yoghurt and oil.
To the 1st cup of flour, add the baking soda, then add the 2nd cup of flour.
Optionally, you can add walnuts or cocoa to part of the mixture and then mix everything in the oven dish.
Bake the cake in an oiled form in a preheated 360°F (180 °C) oven until your toothpick comes out dry when you poke it.
