Instructions
Whisk egg whites with half the amount of sugar and vanilla sugar into a thick white foam, then slowly mix in water and oil, then only with the help of a spatula, fold in flour with baking powder and finally beaten egg whites with a pinch of salt and the other half of sugar.
Separate 1/3 of the batter into another bowl and color it with cocoa. Then using two tablespoons, place in the center of a greased and flour-dusted cake pan (I have a diameter of 23cm) alternately 2 tablespoons of light batter and then 1 tablespoon of dark batter.
After finishing, under no circumstances smooth the surface, it would ruin the drawing! Place in the oven and bake for about 50 minutes at 180 degrees Celsius (test with a toothpick). After slight cooling, sprinkle (the created bump on the surface will even out :-)
