In a large bowl, beat the cream cheese and sugar together with a hand mixer until light and fluffy, about 2 minutes.
By hand, gently fold in the Cool Whip until fully incorporated.
Fold in the marshmallows and cherry pie filling until evenly distributed.
Cover and refrigerate for at least 2 hours before serving to allow flavors to meld.
Scoop into bowls or cups and enjoy this fluffy cherry cheesecake dream!
