French Vanilla Buttercream
makes enough to frost 24 cupcakes
Ingredients
75 grams egg yolks (about 4 egg yolks)
100 grams sugar (1/2 cup)
110 grams light corn syrup (about 2 2/3 tablespoons)
300 grams unsalted butter, softened (about 2/3 pound)
4 grams pure vanilla extract (about 1 teaspoon)
Directions
In the bowl of a stand mixer fitted with the whisk attachment, beat the egg yolks until light yellow in color; turn off the mixer until you're ready to add the hot sugar syrup.
In a heavy-bottomed saucepan, heat the sugar and corn syrup together, stirring constantly, until the mixture comes to a full rolling boil.
Immediately pour a small amount of the hot syrup into the beaten egg yolks and turn the mixer on right away for a few seconds; turn off and scrape the inside of the bowl with a spatula.
Repeat the process using 1/2 of the remaining sugar syrup; mix again for several seconds, turn off, and scrape bowl.
Add the remaining sugar syrup and turn the mixer back on, this time allowing it to continue to mix until the egg mixture is completely cool, about 5 minutes (feel the bottom of the bowl to gauge the temperature of the mixture).
When the egg mixture is completely cool, beat in the softened butter and vanilla extract, scraping down the sides of the bowl once or twice.
Pipe buttercream onto completely cooled cupcakes.
Garnish as desired and serve cupcakes at room temperature.
Refrigerate unused buttercream - allow to come to room temp before using (you may need to whisk the room temp buttercream to restore its creamy texture).
