Preheat the oven to 350 degrees F and spray a 9X5 loaf pan with a non-stick cooking spray. Set aside.
In a mixing bowl, whisk together the flour, baking powder, ground cinnamon, nutmeg and salt.
In a separate bowl of a stand up mixer, beat together the eggs, sugar, butter, eggnog, vanilla extract and rum flavored extract.
Then add the flour mixture into the eggnog mixture and stir in with a spatula or wooden spoon until just combined.
Pour the batter into a prepared pan. Bake for 50-65 minutes until a toothpick inserted into the center of the bread comes out clean.
Let the bread cool in the pan for 10 minutes and then carefully move it to a wire rack to cool completely.
While the bread is cooling, whisk together the glaze ingredients in a mixing bowl.
Drizzle the glaze over the cooled eggnog bread.
Then the bread is ready to slice, serve and enjoy!
