Preheat your oven to 350°F. Generously butter the baking dish.
In a medium bowl, toss the apples with ⅓ cup white sugar and ½ tsp of cinnamon. Set aside while you prepare the cake batter.
In the bowl of a stand mixer, beat together the 1½ sticks of softened butter and the remaining 1 cup of sugar until fluffy. Add the eggs one at a time and mix each one until incorporated before adding the next.
Turn the mixer down and carefully add both flours, baking powder, baking soda, ½ tsp cinnamon, pinch of cloves, salt, and buttermilk. At this point, fold the batter with a rubber spatula so that you do not overmix.
Take half of the apples and spread them evenly over the bottom of the prepared baking dish, then pour the batter on top. Arrange the remaining apples on top in any pattern that you feel like!
Bake the cake for 1 hour, rotating halfway through baking, testing with a toothpick or cake tester to make sure it's fully done before removing from the oven. Allow to cool at least slightly before sprinkling with powdered sugar and/ or whipped cream. YUM!
