In the bowl of a stand mixer fitted with the paddle attachment, beat cream cheese at medium-low speed until smooth, about 1 minute. Add sugar, and beat at medium speed until sugar dissolves and mixture is smooth, 1 to 2 minutes, stopping to scrape sides of bowl. Gradually add cold cream, beating until combined. Scrape sides of bowl. With mixer on low speed, add vanilla bean paste and salt; slowly increase mixer speed to medium-high, and beat until thickened and stiff peaks form, 1 to 2 minutes. Use immediately.
