Creating Truly Sticky Banana Bread Pudding Cake is straightforward if you follow these simple 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, add the cubed bread. Set aside.
3. Mix Wet Ingredients: In another bowl, whisk together the mashed bananas, milk, eggs, sugar, vanilla extract, cinnamon, and salt until well combined.
4. Combine Mixtures: Pour the wet mixture over the bread cubes. Gently fold until the bread is fully soaked and combined.
5. Add Nuts: If using, fold in the chopped walnuts or pecans for added texture and flavor.
6. Transfer to Baking Dish: Pour the mixture into the greased baking dish, spreading it evenly.
7. Bake: Place in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
8. Cool: Remove from the oven and let it cool for about 10-15 minutes before serving.
9. Serve: Cut into squares and serve warm, with whipped cream or a scoop of ice cream if desired.
