Preheat your oven to 325°F (163°C). Grease a 9-inch bundt pan lightly with non-stick cooking spray. Put aside.
Take a large mixing bowl. With a hand mixer set to medium speed, blend together the sugar, vegetable oil, vanilla extract, and eggs.
In another bowl, sift the flour and combine it with the baking soda, cinnamon, and kosher salt.
Incorporate the sifted dry ingredients into the sugar-oil mixture. Mix only until they come together.
Fold in the chopped Granny Smith apples into the batter. Avoid overmixing.
Empty the batter into your prepared bundt pan and smooth out the top.
