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

1. Combine Dry Ingredients: In a medium saucepan, whisk together the sugar, cornstarch, and salt.
2. Mix Wet Ingredients: In a separate bowl, combine the milk and heavy cream. Gradually pour this mixture into the saucepan while whisking to eliminate lumps.
3. Heat the Mixture: Place the saucepan over medium heat. Continuously stir until the mixture thickens and begins to bubble, about 5-7 minutes.
4. Temper the Egg Yolks: In a small bowl, whisk the egg yolks. Slowly add a bit of the hot pudding mixture to the egg yolks, whisking constantly to prevent scrambling.
5. Combine Yolks with Pudding: Pour the egg yolk mixture back into the saucepan, stirring continuously for another 2-3 minutes until thickened.
6. Add Vanilla: Remove the saucepan from heat and stir in the vanilla extract.
7. Layer the Pudding: In a trifle dish or individual cups, layer the vanilla wafers, sliced bananas, and pudding. Repeat the layers until all ingredients are used, finishing with a layer of pudding on top.
8. Chill: Cover the dish with plastic wrap and refrigerate for at least 25 minutes to allow the flavors to meld.
9. Serve: Before serving, top with whipped cream and additional banana slices if desired.
