In a large bowl, beat together the eggnog, eggs, 1/4 cup of sugar, 1 teaspoon of vanilla extract, nutmeg, and cinnamon. Stir in the bread cubes, raisins, and pecans.
Pour the mixture into the prepared baking dish. Drizzle with melted butter. Bake for 30 minutes in the preheated oven, until golden brown.
Meanwhile, in a small saucepan over medium heat, combine the rum, coconut milk, 1/4 cup of sugar, and 1 teaspoon of vanilla extract. Stir until the sugar is dissolved, and simmer for 10 minutes.
