Pre-Heat oven to 350°F
Liberally grease a bundt pan, making sure to get in all the crevices.
Peel and chop apples into bite size pieces and place in a large bowl.
Sprinkle the apples with the cinnamon, 5 tsp of sugar, and 2 tbsp flour; mix, and taste. If apples are a bit tart add a bit more sugar. Set aside.
To the bowl of a mixer, add the flour, 2 cups of sugar, and the baking powder; mix well.
In a separate bowl add the eggs, oil, orange juice, and vanilla extract. Mix well then add to flour mixture. Mix until just combined, the batter will be thick.
Stir in the chopped apples making sure they are thoroughly combined.
Pour the batter into the greased bundt pan and place the pan on top of a baking sheet to catch any spills.
Bake at 350°F for 1 - 1/2 hrs or until a tester inserted in center comes out clean.
Let the cake cool for 5 min then flip bundt cake out onto a desired plate of choice and let it cool completely.
Sprinkle with powdered sugar or caramel drizzle if desired, just before serving.
