Add the marshmallow creme and cream cheese to a medium bowl.
Using a mixer, mix until smooth.
Add vanilla and use a spatula to stir and incorporate.
Chill until ready to serve.
Place the cut fruit on a platter in the shape of a rainbow. I used ROYGBIV for the rainbow colors. My fruits of choice: strawberries, oranges, mangos, bananas, kiwi, blueberries, grapes.
Add the chilled dip to two small bowls. I use a ice cream scoop to give the dip a rounded "cloud" shape.
Place the bowls of dip on either side of the fruit rainbow and serve.
