Creating your Apple Bread Pudding is simple and rewarding. Follow these steps for a delicious result:

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. Toss them together gently.
3. Mix the Custard: In another bowl, whisk 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. Stir gently to ensure everything is coated.
5. Add Raisins: If using, fold in the raisins for added texture and sweetness.
6. Drizzle Butter: Pour the melted butter over the mixture, ensuring even distribution.
7. Let it Soak: Allow the mixture to sit for about 15 minutes, so the bread absorbs the custard.
8. Bake: Transfer the mixture to the prepared baking dish and bake for 40-45 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
9. Cool Slightly: Once baked, remove from the oven and let it cool for 10-15 minutes before serving.

These straightforward steps will lead you to create a delightful Apple Bread Pudding that warms the heart and pleases the palate.
