Whisk together the flour, sugar, baking powder, salt, and nutmeg in the mixing bowl. Add the eggnog, oil, and eggs. Stir well, until all the dry ingredients are coated, but don’t over mix.
For each waffle, pour 3/4 cup of batter onto the hot waffle iron, spreading it around lightly to even it out a bit, then cook according to the manufacturers directions. Keep finished waffles warm in the oven at 150° F until ready to serve.
