Beat the eggs with sugar and a little salt until they are very frothy, at least 5 minutes (I use my magic wand here, for example).
Pour in the liquid and oil quickly while stirring slowly (preferably with the help of a food processor or a helping hand).
Mix the flour with the baking powder and fold in, preferably sifted. It should now only be stirred a little, otherwise the dough will lose its volume.
Tip: If you prefer a dark dough, you can add 1 - 2 tablespoons of cocoa to the egg mixture with the flour.
Now fill the dough into a greased pan and / or lined with baking paper and bake at 180 ° for 40 - 50 minutes. As always, the exact baking time depends on various factors such as the type of stove, cake pan, cake size, etc.! Therefore make a chopstick test.
