• Add your all-purpose flour and whole wheat flour to a large bowl. Next, add in your baking powder, baking soda, salt, and apple pie spice. Whisk all of those ingredients together. Set aside.
• In the bowl of a stand mixer, add in the eggs, vanilla extract, vegetable oil, apple cider, apple sauce, brown sugar, and granulated sugar. Use the paddle attachment and beat together wet ingredients on low speed until they're combined well. Add bowl of dry ingredients to your mixer bowl. Mix on low speed until there are just a few streaks of flour left. Peel and slice your apple into cubes. Remove bowl from the mixer. Fold in the cubed apple pieces.
• Preheat your oven to 350°F. Evenly coat your bundt pan with nonstick spray. Pour in the apple cider cake batter. Place in the oven, on the bottom rack. Baking time is between 50-55 minutes. A toothpick inserted should come out mostly clean.
• After removing your cake from the oven, place it on a wire rack to cool for about 15 minutes. Invert your bundt pan onto the wire rack and tap a few times to release the warm cake from the mold. Make your glaze while you allow your cake to cool for a few more minutes.  

Apple Cider Glaze

• n a medium bowl, whisk together the powdered (confectioners') sugar and apple cider. You can add more apple cider for a runnier consistency. Pour glaze over the entire cake.

Cinnamon & Sugar Mix

• In a small bowl, combine 1 tsp of cinnamon with 1/4 cup granulated sugar. Sprinkle this over the apple cider glaze.
