Preheat the oven to 350F.
Sift all the dry ingredients together in a medium bowl (flours, cinnamon, powder, soda, salt) and set aside.
In a large bowl or in a stand mixer, beat together all the wet ingredients until combined (oil, syrup, milk, applesauce, eggs, vanilla).
Add the dry ingredients to the wet and mix on low until just combined.
Mix your chopped apple with cinnamon and flour then fold into the batter.
Let the batter sit while you line a loaf pan with parchment paper.
Pour batter into your lined loaf pan and bake for 45-50 minutes, until a toothpick comes out clean.
Let the loaf cool in the pan for 10-15 minutes before removing to finish cooling on a wire rack.
Cool completely before slicing. Enjoy!
