STEP 2:
Remove the bowl of egg whites from the heat & beat the egg whites with the sugar for 7-10 minutes on high speed and then lower the speed to low-medium.
STEP 3:
Slowly add 2 Tbsp of butter at a time. Once all the butter is added, turn the mixer up to high speed for a few seconds, until it comes together.
STEP 4:
Use a rubber spatula to scrape the edge of the bowl. Add the vanilla bean paste (or extract) and salt and beat until it's fully combined. Enjoy!
