Follow these simple steps to create your own Bananas Foster Bread Pudding:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish.
2. Prepare Bread: Place the cubed bread in a large bowl and set aside.
3. Mix Custard: In another bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, cinnamon, and salt until well combined.
4. Combine Mixtures: Pour the custard mixture over the cubed bread, gently folding to ensure all pieces are coated. Let it sit for about 15 minutes to absorb the custard.
5. Add Bananas: Fold in the sliced bananas and chopped nuts if desired.
6. Transfer to Baking Dish: Pour the bread mixture into the prepared baking dish, spreading it evenly.
7. Make Sauce: In a small saucepan over medium heat, melt the butter. Stir in the brown sugar and rum, cooking until the sugar dissolves and the mixture is bubbly.
8. Drizzle Sauce: Pour the warm sauce over the bread pudding mixture in the baking dish.
9. Bake: Bake in the preheated oven for 45-50 minutes, or until the top is golden and a knife inserted in the center comes out clean.
10. Cool: Remove from the oven and let it cool for about 15 minutes before serving.
