Eggs are separated. Beat the egg whites with a pinch of salt, add sugar, vanilla sugar and essence. Beat until the egg whites are very well done (to be hard). Add the yolks and mix well. The flour is mixed with the baking powder and put in a sieve and poured in the rain over the composition. Mix with a wooden spoon but from the bottom up and very slowly. The tray in which we will make the cake is greased with oil or butter and covered with flour. The composition is poured into the tray and put in the preheated oven. Whoever wants can stop a little composition and mix it with cocoa as I did. Leave in the oven until it passes the toothpick test but over medium heat.
Good appetite !!!
