Creating Banana Foster Pudding can be straightforward if you follow these simple steps:

1. Prepare the Bananas: Slice the bananas into rounds and set aside.
2. Make the Caramel Sauce: In a medium saucepan over medium heat, combine the sugar and butter. Stir constantly until the mixture is melted and bubbly.
3. Add Rum: If using, carefully add the dark rum to the caramel sauce. Be cautious, as it may flame up. Stir until well combined.
4. Add Bananas: Gently fold in the sliced bananas to coat them in the caramel sauce. Cook for 2-3 minutes until the bananas are slightly softened. Remove from heat and set aside.
5. Prepare Pudding Base: In another saucepan, combine milk, heavy cream, salt, and cinnamon. Heat over medium until it begins to simmer, stirring occasionally.
6. Mix Cornstarch and Egg Yolks: In a separate bowl, whisk together the cornstarch and egg yolks until smooth.
7. Temper the Egg Mixture: Slowly pour the hot milk mixture into the cornstarch and egg yolk mixture, stirring constantly to prevent curdling.
8. Thicken the Pudding: Return the combined mixture to the saucepan over medium heat. Cook, stirring constantly, until the mixture thickens and coats the back of a spoon (about 5-7 minutes).
9. Add Vanilla: Once thickened, remove from heat and stir in the vanilla extract.
10. Layer the Pudding: In a glass dish or individual serving cups, layer the caramelized bananas and pudding alternately. Start with a layer of pudding, followed by a layer of bananas, and repeat until all ingredients are used.
11. Chill: Cover the dish with plastic wrap and refrigerate for at least 45 minutes to allow the flavors to meld and the pudding to set.
12. Serve: Once chilled, top with whipped cream and additional banana slices if desired.
