Creating Easy Eggnog Apple Bread Pudding is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
2. Prepare Bread: In a large bowl, combine the cubed bread and diced apples. Toss gently to mix.
3. Mix Eggnog Mixture: In another bowl, whisk together the eggnog, eggs, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined.
4. Combine Mixtures: Pour the eggnog mixture over the bread and apples, ensuring everything is evenly coated. Let it sit for about 10 minutes to absorb the liquid.
5. Add Raisins: If using, fold in the raisins for added sweetness and texture.
6. Transfer to Baking Dish: Pour the bread mixture into the prepared baking dish. Drizzle melted butter over the top.
7. Bake: Place in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
8. Cool: Remove from the oven and let it cool for 10-15 minutes before serving.
9. Dust with Powdered Sugar: For an elegant touch, dust the top with powdered sugar before serving.
