Place 8 ounces of cream cheese in the bowl of a stand mixer (or a large bowl if using an electric hand mixer). Let it sit until it reaches room temperature.
Add 1 (7-ounce) jar of marshmallow creme, 1 tablespoon of frozen orange juice concentrate (if using), 1 teaspoon of vanilla extract, and 1/4 teaspoon of kosher salt. Blend with the paddle attachment on medium speed until combined, about 1 minute.
Transfer to a serving bowl and serve with fresh fruit for dipping.
