Creating Sticky Banana Bread Pudding Cake is straightforward. Just follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
2. Prepare Bread: Place the cubed bread in a large bowl and set aside.
3. Mix Wet Ingredients: In another bowl, whisk together the mashed bananas, eggs, milk, granulated sugar, vanilla extract, cinnamon, and salt until smooth.
4. Combine Mixtures: Pour the banana mixture over the cubed bread. Stir gently to ensure all the bread is soaked.
5. Add Optional Ingredients: If you’re using nuts or chocolate chips, fold them into the mixture now.
6. Transfer to Baking Dish: Pour the mixture into the prepared baking dish, spreading it evenly.
7. Prepare the Topping: In a small bowl, combine the heavy cream, brown sugar, and melted butter. Drizzle this mixture over the top of the bread pudding.
8. Bake: Place the baking dish in the oven and bake for 45-50 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
9. Cool: Once baked, remove from the oven and allow to cool for 10-15 minutes before serving.
