Creating Irresistible Hot Buttered Rum Bread Pudding is straightforward. Follow these steps to ensure success:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C).

2. Prepare the Bread: In a large bowl, combine the cubed bread with the melted butter. Toss to coat the bread evenly.

3. Make the Custard: In another bowl, whisk together the eggs, sugar, and salt until well combined. Add the milk, heavy cream, vanilla extract, cinnamon, nutmeg, and rum. Mix until smooth.

4. Combine Bread and Custard: Gently fold the bread mixture into the custard until all pieces are soaked. Let it sit for about 15 minutes to absorb the custard.

5. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish, spreading it evenly.

6. Bake: Place the dish in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and a knife inserted in the center comes out clean.

7. Cool Slightly: Once baked, remove the pudding from the oven and let it cool for about 10-15 minutes. This will help it set slightly before serving.

8. Serve Warm: For an extra touch, drizzle with additional melted butter or a scoop of vanilla ice cream.

These steps will guide you in creating this incredible dessert effortlessly.
