Sift the powdered sugar and salt into the bowl of the stand mixer (or a large bowl with a hand mixer).
Add the heavy whipping cream and vanilla bean paste on top and beat at medium-low speed for about 1-2 minutes, until it starts to thicken.
Increase the speed to medium-high and continue beating for another 1-2 minutes, until the cream forms stiff peaks. Don't over-beat passed this.
Use the rubber spatula to scrape the edge of the bowl and fold it a couple of times to make it smooth and silky.
