**Preheat your oven to 350°F.**
**Mix graham cracker crumbs, sugar, and melted butter in a large bowl. Save 1 cup of this mixture.**
**Press the remaining graham cracker mixture into the bottom of a 10-inch deep cake pan or pie dish. Bake for 10 minutes and set aside.**
**In a separate bowl, combine pudding mix and milk. Beat until the pudding dissolves and thickens.**
**Use a hand mixer to beat cold heavy cream in a large bowl until soft peaks form. Add powdered sugar and beat until stiff peaks form. Be cautious not to overbeat.**
**Gently fold the whipped mixture into the pudding mix.**
**Assemble the layers: Spread dulce de leche on the crust, add a layer of banana slices, followed by pudding mixture, remaining graham cracker crumbs, a second layer of bananas, and the whipped cream topping.**
**Refrigerate uncovered for at least 4 hours or overnight.**
**Before serving, drizzle caramel sauce on top, and savor every delicious bite!**
