Heat a lightly oiled skillet or griddle over medium heat.

In a bowl, mix flour, sugar, baking powder, and salt. Make a well in the center, and pour in the eggnog, butter, and egg. Mix until dry ingredients are evenly moist.

Pour 1/4 cup batter onto the hot griddle for each pancake and cook pancakes until bubbly on top.

Flip with a spatula, and continue cooking until lightly browned on bottom.
