Wash, peal and dice apples into one inch pieces.

Using a mixer, beat eggs with sugar, until its three times in volume.

Using a spatula, fold in flour by thirds; be very gentle with the dough, to not overmix it and lose the fluffiness.

Lay out the diced apples on the bottom of a 9 inch pan. Cover apples with cake batter, shake the pan a bit, to spread batter between each apple piece.

Bake it at 350F for 40 minutes, check using a wooden toothpick. If the cake is ready, the dough should not stick to the toothpick.

Once the cake cools off a little, dust it with some powdered sugar. (Optionally, you can flip the cake over before dusting with powdered sugar, but this isnt required.)
