Separate egg whites and yolks.
Mix egg yolks and sugar in a bowl.
Add sifted cake flour and milk to the yolk mixture and blend.
Gradually add sugar to the egg whites and whisk to make meringue.
Fold the meringue into the yolk batter in 2 to 3 portions.
Pour the batter into a mold and bake for 35 minutes in an oven preheated to 150°C.
After cooling, cut in half horizontally and fill with whipped fresh cream.
