In a large mixing bowl, stir together the whipped topping/Cool Whip, cherry pie filling, sweetened condensed milk and sour cream.
Fold in the mini marshmallows, pineapple chunks, bananas, walnuts, maraschino cherries and mini chocolate chips until well-combined.
Cover with plastic wrap and chill in the fridge for at least 30 minutes before serving to allow flavors to come together. Plus, it tastes best chilled!
Drizzle on chocolate sundae syrup (optional). Serve cold. Enjoy!
