Place the 6 large egg yolks in the bowl of a stand mixer equipped with the whisk attachment.
2
Add 1 cup granulated sugar to a small 2-quart saucepan and carefully pour ½ cup water around the edges. Do not stir, and turn the heat to medium to allow the mixture to come to a boil.
3
As soon as the sugar syrup begins to boil, attach a candy thermometer.
4
When the mixture reaches around 220° F, begin whisking the egg yolks on medium.
5
When the sugar syrup reaches 239° F, remove from heat. With the mixer running at high speed, slowly and carefully pour the hot sugar syrup into the egg yolks, targeting the spot between the whisk and the sides of the bowl.
6
Continue to whip until the mixture is light, fluffy, and cool to the touch.
7
Gradually beat 1½ cups butter into the yolk mixture, a few tablespoons at a time, until all the butter is incorporated. The mixture may appear curdled at this stage, but continue mixing, and it will become smooth.
8
Add 1 teaspoon pure vanilla extract and mix until combined.
9
Use the buttercream immediately or refrigerate in an airtight container for up to two weeks. It can also be frozen for up to three months.
