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

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
2. Prepare the Bread: In a large bowl, combine the cubed bread and diced apples. Ensure the bread is evenly mixed with the apples.
3. Mix the Custard: In another bowl, whisk together the eggnog, eggs, sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined.
4. Combine Mixtures: Pour the custard mixture over the bread and apple mixture. Gently stir until the bread is fully soaked. If using, fold in the raisins or dried cranberries.
5. Let It Soak: Allow the mixture to sit for about 10-15 minutes, giving the bread time to absorb the custard.
6. Bake: Pour the mixture into the prepared baking dish and spread it evenly. Bake in the preheated oven for 40-45 minutes or until the top is golden brown and a toothpick inserted in the center comes out clean.
7. Cool and Serve: Once baked, remove from the oven and let it cool for about 15 minutes before serving. Serve warm with whipped cream or a scoop of vanilla ice cream if desired.
