Preheat oven at 350F and generously grease your loaf pan including all the corners and edges.
In a mixing bowl, add in all your wet ingredients and sugar then mix well together. This would be your eggs, eggnog, white sugar, butter, and vanilla.
Once all your sugar and wet ingredients have been combined, add in your nutmeg, baking powder, and flour. Be sure to add in your flour 1/2 cup at a time to avoid clumps!
When your batter is all well combined and there are no lumps, pour into your greased loaf pan. Optional: Sprinkle a little more nutmeg on top.
Bake in the oven at 350F for about 60-80 minutes or until you can poke the middle of the loaf with a toothpick and the toothpick comes out clean.
Slice, serve and enjoy!
