1. Preheat oven to 350°F (175°C) and grease a 9×5 inch loaf pan, lining it with parchment paper for easy removal.

2. In a large bowl whisk together flour, baking powder, baking soda, salt, cinnamon, and nutmeg until evenly combined.

3. In a separate bowl beat together brown sugar, vegetable oil, eggs, and vanilla extract until smooth and slightly frothy, then stir in apple cider and applesauce if using.

4. Pour the wet ingredients into the dry ingredients and stir gently until just combined, avoiding overmixing to keep the bread tender.

5. Fold the diced apples into the batter until they are evenly distributed without breaking them up.

6. Pour the batter into the prepared loaf pan and smooth the top with a spatula.

7. Bake for 50 to 60 minutes or until a toothpick inserted into the center comes out clean and the top is golden brown.

8. Allow the bread to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before glazing.

9. Whisk powdered sugar with a few tablespoons of apple cider until smooth, then drizzle the glaze over the cooled loaf and let it set before slicing.
