Classic French buttercream is a rich and silky frosting made with egg yolks, sugar syrup, and butter. This elegant and smooth buttercream is perfect for cakes and cupcakes, offering a luscious vanilla flavor with a creamy texture.

Ingredients

Scale

Egg Yolk Mixture

  • 5 egg yolks

Sugar Syrup

  • 110 g (1/2 cup) granulated sugar
  • 44 ml (3 tbsp) water

Buttercream

  • 227 g (1 cup) butter, softened and diced
  • 1 tsp vanilla extract
  • 1 pinch salt

Instructions

  1. Whip Egg Yolks: Place the egg yolks in the bowl of a stand mixer fitted with the whisk attachment and beat at high speed until they become pale and frothy.
  2. Prepare Sugar Syrup: In a saucepan over medium heat, combine the granulated sugar and water. Heat the mixture, stirring gently until the sugar dissolves, then allow it to reach 239°F (115°C) as measured with a baking thermometer.
  3. Combine Syrup and Yolks: Lower the mixer speed, and carefully pour the hot sugar syrup slowly over the beaten egg yolks to temper them and create a thick custard-like base.
  4. Whip Mixture: Increase the mixer speed to high and beat for about 10 minutes until the sugar yolk mixture cools down and becomes fluffy and thick.
  5. Add Butter and Flavor: Reduce mixer speed, then add the softened diced butter, vanilla extract, and a pinch of salt. Continue to beat on high speed for 5 to 10 minutes until the buttercream becomes smooth, creamy, and spreadable.

Notes

  • Ensure the sugar syrup reaches the correct temperature (239°F / 115°C) to achieve the right consistency in the buttercream.
  • Use softened butter at room temperature to avoid lumps in the final frosting.
  • If the buttercream appears curdled after adding butter, continue beating as it will become smooth with time.
  • This buttercream is best used immediately or stored in the refrigerator for up to 3 days; bring it back to room temperature and whip before use.
