Preheat your oven to 350 degrees F. Spray your loaf pan with cooking spray & set aside.In a large bowl or stand mixer with paddle attachment, add all the wet ingredients and sugar (egg, egg white, eggnog, rum extract, vanilla, stevia, vanilla, melted butter and applesauce). Whisk it all together until blended and smooth.To the same bowl, add in all your dry ingredients (flour, baking powder, salt, nutmeg). Stir until combined.Pour batter into loaf pan and bake for approx 40 minutes, until its golden around the edges and a toothpick comes clean in the middle.Allow to cool fully in pan, then remove from pan and allow to cool further once removed from the pan.Store remainder in an airtight container. After a couple days, its a good idea to put in the fridge to keep it fresh longer.If freezing, wrap tightly in plastic wrap (2 layers).
