Creating Bananas Foster Bread Pudding is simple if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
2. Prepare Bread: In a large bowl, combine the cubed bread and sliced bananas. Toss gently to mix.
3. Mix Custard: In another bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, cinnamon, and salt until smooth.
4. Combine: Pour the custard mixture over the bread and bananas. Gently fold until the bread is fully soaked.
5. Add Rum: If using, drizzle the dark rum over the mixture and fold gently to combine.
6. Transfer to Baking Dish: Pour the mixture into the prepared baking dish, spreading it evenly.
7. Bake: Bake in the preheated oven for 30-40 minutes, or until the top is golden brown and the custard is set.
8. Prepare Sauce: While the pudding is baking, melt the butter in a saucepan over medium heat. Add the brown sugar and stir until dissolved. Cook for 2-3 minutes until the mixture is bubbly and caramelized. Remove from heat and add the remaining rum (if using).
9. Cool: Once the bread pudding is done, remove it from the oven and let it cool for about 10-15 minutes.
10. Serve: Drizzle the warm caramel sauce over the pudding before serving, and sprinkle with chopped nuts if desired.
