Preheat your oven to 350 degrees.

Peel and dice the apples, then toss them with 5 tablespoons sugar and 1 tablespoon cinnamon. Set aside.

In a mixing bowl, beat eggs on low speed, then add sugar, beating until combined.

Add half of the cake flour, the baking powder, and salt.

Beat in the oil, orange juice, vanilla, and then the remaining cake flour. Beat just until combined.

Pour half of the batter into a greased and floured Bundt pan.

Place half of the apples over the batter, then pour on the remaining batter.

Spread the rest of the apples on the top.

Bake 50-60 minutes, or until the cake is starting to pull away from the sides and a toothpick inserted into the center comes out clean.

Cool in the pan for 15 minutes, then remove from the pan and cool completely.
