Place the butter in the bowl of a stand mixer, then sift the powdered sugar on top. Fit the machine with a paddle attachment, and mix on low until the powdered sugar is fully incorporated. Add vanilla and salt, then increase speed to medium and beat until the frosting is airy and light, pausing along the way to scrape the bowl and beater as needed. This will take about 6 minutes, although the exact timing will vary depending on the power of the machine.
