Beat the softened cream cheese in a mixing bowl until completely smooth.
Sift in the powdered sugar and cocoa. Mix on low until combined, then beat until fluffy.
Blend in the vanilla and salt.
Slowly stream in the heavy cream while mixing until the dip is light and scoopable.
Fold in the mini chocolate chips. Taste and adjust sweetness or cocoa to preference.
Serve immediately or chill 10–15 minutes for a thicker texture. Garnish with extra chips, if desired.
