Separate the egg yolks and whites. In a bowl, mix the yolks with milk, oil, and vanilla. Sift in the flour and cornstarch, then mix until smooth. In another bowl, add a few drops of lemon juice to the egg whites and beat until stiff peaks form. Gently fold a small amount of the egg whites into the yolk mixture to lighten it, then fold the yolk mixture back into the remaining egg whites until fully combined.

Make sure both mixtures are well blended together.

Pour the batter into a rectangular pan. Preheat the oven to 270°F (160°C) and bake for 10 minutes.
