In a large mixing bowl, whisk together eggnog, eggs, maple syrup, oil, and vanilla until well combined.
Add the flour, baking powder, cinnamon, and nutmeg and stir until well combined and no flour lumps remain.
Heat your pancake maker or large skillet over medium heat and add oil to coat. Once preheated, add ¼ cup of the batter to the pan or to each pancake well. Cook for 2-3 minutes, then flip the pancake and continue to cook for another 1-2 minutes or until done through the middle.
Repeat step 4 with remaining batter (you should have 20 pancakes), then serve with your favorite pancake toppings!
