In the top pan of a double boiler, combine egg whites, sugar and salt. Whisk constantly over simmering water until mixture reaches 160°F on an instant read thermometer, about 20 minutes.
Transfer mixture to a stand mixer fitted with a whisk attachment. Whip until the bowl is cool to the touch and the mixture holds medium peaks.
Switch to a paddle attachment on the mixer. Beat at medium speed while adding the butter one piece at a time, scraping bottom of the bowl as necessary. Add vanilla and beat until well combined.
