Begin by preheating the oven to a temperature of 350°F. A bundt pan should be amply coated with non-stick cooking spray and set aside for subsequent use.

In a small mixing bowl, combine 1 tablespoon of ground cinnamon with ¼ cup of granulated sugar. Proceed to toss the finely chopped apples in this mixture until they are evenly coated. Reserve this for later.

In a separate, larger bowl, sift together the all-purpose flour, kosher salt, and baking powder. Once sifted, set this mixture aside.

In yet another bowl, combine the vegetable oil, 1 cup of granulated sugar, 1 cup of light brown sugar, the eggs, vanilla extract, and orange juice. Thoroughly whisk these ingredients together until they form a homogenous mixture.

Gradually incorporate the wet mixture into the dry flour mixture, ensuring they are blended seamlessly.

Into the previously prepared bundt pan, pour half of the batter. This should be followed by a layer consisting of half of the apple mixture. Repeat the process with the remaining batter and apple mixture.

The bundt pan should then be covered securely with aluminum foil and placed in the oven to bake for 45 minutes. After this initial period, carefully remove the aluminum foil and continue baking for an additional 45 minutes. The cake will be deemed ready once a tester, when inserted into the center, emerges cleanly.

Once baked, the cake should be removed from the oven and allowed to cool. Prior to serving, it is recommended to garnish the cake with a fine dusting of powdered sugar.
