Follow these simple steps to create your Banana Pudding Tiramisu with Caramel:

1. Prepare the Cream Mixture: In a large bowl, whip the heavy cream until stiff peaks form.
2. Combine Pudding Ingredients: In another bowl, mix the mascarpone cheese, powdered sugar, vanilla extract, and mashed bananas until smooth.
3. Fold in Whipped Cream: Gently fold the whipped cream into the banana-mascarpone mixture until well combined.
4. Prepare Coffee Mixture: In a shallow dish, combine the cooled brewed coffee and coffee liqueur (if using).
5. Soak Ladyfingers: Quickly dip each ladyfinger into the coffee mixture, ensuring they are soaked but not soggy.
6. Layer the Ingredients: In a serving dish, arrange a layer of soaked ladyfingers at the bottom. Spread a layer of the banana pudding mixture over the ladyfingers.
7. Repeat Layers: Continue layering with soaked ladyfingers and banana pudding mixture until all ingredients are used, finishing with the pudding layer on top.
8. Chill: Cover the dish with plastic wrap and refrigerate for at least 1.5 hours to allow the flavors to meld.
9. Drizzle with Caramel: Before serving, drizzle caramel sauce over the top of the chilled tiramisu.
10. Garnish and Serve: Add additional banana slices on top for garnish.
