In a large mixing bowl, combine the cream cheese, instant pudding mix, vanilla extract, milk, and Cool Whip. Beat until the mixture is smooth.
Gently fold in the cherry pie filling and mini marshmallows until they are evenly distributed throughout the mixture.
Cover the bowl and refrigerate for up to 24 hours to allow the flavors to blend and the dessert to set.
Serve chilled, offering a delightful treat to your guests.
