French buttercream is a rich and velvety frosting made with whipped egg yolks, sugar syrup, and butter. It has a luxurious texture and is perfect for cakes, cupcakes, or other desserts.
**For the Pâte à Bombe:**
120 g (from about 7 large eggs) egg yolks
80 g (⅓ cup) water
200 g (1 cup) granulated sugar
**For the Buttercream:**
450 g (2 cups) unsalted butter, softened
⅛ teaspoon salt (optional)
Ensure butter is soft at room temperature to avoid grainy buttercream.
Don’t skip the cooling of the pâte à bombe before adding the butter for the best texture.
For best results, use a scale to measure ingredients.
