Preheat your oven at 350°F (175°C)
In a large bowl, add the flour, cinnamon, nutmeg, baking powder, baking soda and salt. Stir gently with a fork to combine.
In the other bowl, add the sugar and melted butter and mix it until creamy with a hand mixer. About 1-2 minutes on medium-high speed.
Add the two eggs and mix well.
Then add the applesauce and vanilla extract and mix well.
Next, add your dry ingredients to the bowl with the sugar mixture and fold in using a spatula and stir just until combined. It will take some mixing, but make sure to stop once combined so you don't overmix.
Add the warmed milk and mix well with your spatula to finish your batter.
Pour the batter evenly into a mini loaf pan with 8 cavities or into a regular-sized loaf pan.
(Optional) Place a half of a thin slice of apple on top of each loaf.
Bake for approximately 20-25 minutes. Check doneness with a toothpick at the 20 minute mark. Mine took about 22 1/2 minutes.
Sprinkle a little bit of cinnamon on top of each loaf. Let cool to the touch, remove from the pan and place them on a platter to serve.
