Creating this wonderful Apple Bread Pudding is straightforward. Follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a large baking dish (9×13 inches works well) with butter or non-stick spray.
2. Prepare the Bread: In a large bowl, combine the cubed bread with the diced apples. Toss gently to distribute evenly.
3. Make the Custard Mixture: In another bowl, whisk together the eggs, milk, sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined.
4. Combine Mixtures: Pour the custard mixture over the bread and apples. Use a spatula or your hands to gently mix, ensuring all the bread is coated.
5. Add Optional Ingredients: Stir in raisins or nuts if using, for added texture and flavor.
6. Transfer to Baking Dish: Spoon the mixture into the prepared baking dish, spreading it out evenly.
7. Drizzle with Butter: Pour the melted butter evenly over the top of the mixture.
8. Bake: Place in the preheated oven and bake for 40-45 minutes, or until the top is golden brown and the custard is set.
9. Cool: Remove from the oven and let it cool for about 10-15 minutes before serving. This will help it set further.
