Step 1

Preheat the oven to 400 degrees F (200 degrees C). Line an 11-inch round baking pan with parchment paper.

Step 2

Combine sliced apples, 1/2 cup white sugar, butter, and brown sugar in a large bowl. Mix together gently, being careful not to break apple slices. Pour sugary juice from the apple mixture into the prepared baking pan. Arrange sliced apples on top in a circle. Sprinkle raisins on top of apples and pour any remaining juice over all.

Step 3

Combine olive oil and cinnamon in a large mixing bowl. Add egg yolks, flour, grated apples, baking powder, and remaining white sugar. Stir well to combine. Beat egg whites to a light froth in a separate bowl and stir into the olive oil mixture carefully. Pour over the apples in the baking pan.

Step 4

Bake in the preheated oven until a knife inserted in the center comes out clean, about 45 minutes. Cover cake with foil if the top browns before the cake is done baking.

Step 5

Remove cake from oven and allow to cool, about 30 minutes. Invert cake onto a serving plate.
