Creating Truly Sticky Banana Bread Pudding Cake is easy if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
2. Prepare Bread: In a large bowl, combine the cubed bread and mashed bananas. Toss gently to combine.
3. Make Custard: In another bowl, whisk together the eggs, granulated sugar, milk, cream, vanilla extract, cinnamon, and salt until smooth.
4. Combine Mixtures: Pour the custard mixture over the bread and banana mixture. Stir gently to ensure all bread is coated. Let it sit for about 15 minutes to allow the bread to absorb the custard.
5. Prepare Caramel: In a small saucepan, melt the butter over medium heat. Add the brown sugar and stir until dissolved, creating a smooth caramel sauce.
6. Add Caramel: Drizzle half of the caramel over the bread mixture and gently fold it in.
7. Transfer to Baking Dish: Pour the mixture into the prepared baking dish, spreading it evenly.
8. Bake: Place in the oven and bake for 40-45 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
9. Cool: Remove from the oven and let it cool for 15 minutes before serving. Drizzle the remaining caramel over the top while still warm.

These steps will guide you in creating this incredible dessert effortlessly, ensuring it becomes a cherished favorite.
