In a large mixing bowl, beat the softened cream cheese with an electric mixer on medium speed until smooth and fluffy, about 2 minutes.
Add pumpkin puree, brown sugar, powdered sugar, vanilla extract, pumpkin pie spice, cinnamon, and salt. Beat until completely combined and creamy.
Using a spatula, fold in the mini chocolate chips, reserving a few tablespoons for topping.
Transfer the dip to a serving bowl and sprinkle the reserved chocolate chips on top for presentation.
Refrigerate for at least 30 minutes before serving to allow flavors to meld and the dip to firm up slightly.
Serve chilled with graham crackers, apple slices, pretzels, or your favorite dippers. Store covered in the refrigerator for up to 5 days.
