Break the eggs in a bowl and add the sugar. Beat with a mixer until whitened.
Once beaten well, gradually add the flour, while stirring with a wooden spoon.
Pour the mixture into a well oiled and floured form. Bake at 392°F (200 °C) about 30 min.
Poke it with a toothpick to see if it's baked properly.
Optionally, sprinkle with powdered sugar.
