Preheat broiler. Meanwhile, cream together cream cheese, vanilla and powdered sugar.
Line a rimmed baking sheet with foil and spray with nonstick spray. Spread marshmallow creme on one side and the mini marshmallows on the other. Place under broiler and watch extremely carefully. Broil until brown and toasty. This will take less than a minute so don't take your eyes off it. Remove from oven and allow to cool.
Stir marshmallow creme, mini marshmallows and chocolate chips into the cream cheese mixture. Refrigerate for at least an hour. Serve with graham crackers and fruit.
