In a shallow dish or medium bowl, combine the eggs, eggnog, sugar, vanilla, cinnamon, ginger, nutmeg, and rum extract if using.
Melt ½ tablespoon of butter in a skillet over low-medium heat.
Dip a piece of bread into the egg mixture ensuring that both sides are equally coated. Then place the soaked bread onto the hot skillet. Cook for 2 to 4 minutes on each side (enough to cook the eggs and give the bread a golden brown color).
Remove the French toast from the skillet, and transfer to plate. Carefully wipe away any browned butter from the skillet with a paper towel.
Repeat until all the bread and egg mixture have been used. Serve hot with your favorite toppings.
