Preheat oven to 350 degrees and grease a 9x5 loaf pan or 5 mini loaf pans. In a medium bowl, combine the applesauce, sugar, vegetable oil, eggs, and milk. Slowly add in the flour, baking soda, baking powder, cinnamon, nutmeg, pumpkin pie spice, and salt. Stir until just combined. Pour batter into prepared loaf pan(s) and place in oven to bake for 30 minutes if making mini loaves, or about 60 minutes if making large loaf.
