Preheat the oven to 375°F.
Whisk together the sugar, cake flour, salt, cloves, baking powder, and nutmeg in a large mixing dish.
Combine together the oil, melted butter, milk, eggs, and vanilla extract in a separate dish.
Peel and slice the apples, then slice into bite-size slices and toss with the flour mixture.
Stir the milk mixture into the flour and apple mixture just until mixed to form a sticky dough.
Spread the batter into the prepared pan, spreading to the borders and topping with the remaining sugar on top.
Preheat the oven to 350°F and baked for 50 minutes, or until a wooden skewer in the middle pulls out cleanly.
