Preheat the oven to 350 degrees Fahrenheit. Line the baking pan with parchment paper.

Beat the egg whites until peaks start to form.

Add half a cup of the sugar and beat until the whites are stiff and glossy.

In a second bowl, beat together the egg yolks, whole eggs and remaining sugar. Add the oil and vanilla sugar until it is lemon-colored.

In a third bowl or Ziploc bag, combine the remaining ingredients.

Using a very large bowl, add half of each of the three mixtures, starting and ending with the egg whites. Fold all of the mixtures together well, but gently.

Pour the combined batter into the prepared pan and bake for 50–60 minutes.
