Grease a bundt pan and sprinkle with a little flour to coat.
In a small bowl, combine 2 teaspoons of cinnamon and 1/3 cup sugar. Toss the apples with the cinnamon sugar mixture and set aside.
In a large mixing bowl combine flour, salt, baking powder, 2 cups of sugar, vegetable oil, eggs, orange juice, vanilla, and the remaining 1 teaspoon of cinnamon. Mix well.
Pour half of the batter into the tube pan or a bundt pan, and then half of the apple cinnamon mixture. Repeat with the batter and apples. You can also add an extra sprinkle of cinnamon sugar to the top if you desire.
Bake in the oven for 70-90 minutes or until a toothpick comes out with minimal crumbs.
