In a small saucepan sprinkle gelatin over milk. Let stand 5 minutes. Cook and stir over medium heat until gelatin is dissolved. Let cool 10 minutes.
In a large bowl beat cream cheese with a mixer on medium speed until smooth. Beat in marshmallow creme and vanilla. Gradually beat in cooled milk mixture until smooth.
Pour cream cheese mixture into the cooled crust; cover. Chill up to 8 hours or until set. Top with strawberries and peaches just before serving.
