Prepare the Meringue: In a heatproof bowl, combine the egg whites and sugar. Place the bowl over a pot of simmering water, ensuring the bottom of the bowl doesn't touch the water. Whisk constantly until the sugar has dissolved and the mixture reaches 160°F (71°C) on a candy thermometer.
4 large Egg whites, 1 cup Granulated sugar
Whip the Meringue: Remove the bowl from heat and using a hand mixer or stand mixer, beat the egg white mixture on high speed until stiff peaks form and the mixture is cool to the touch, about 10-15 minutes.
Add Butter: Reduce the speed to medium-low and add the butter, a few tablespoons at a time, mixing well after each addition. The mixture may look curdled at some point, but continue mixing until it becomes smooth and creamy.
1½ cups Unsalted butter
Add Flavoring: Add vanilla extract or any other flavorings you desire and mix until well combined.
1 tsp Vanilla extract
Use or Store: Use the buttercream immediately to frost cakes or cupcakes, or store it in an airtight container in the refrigerator for up to a week. Before using, bring it back to room temperature and re-whip it until fluffy.
