How to make white chocolate Swiss meringue buttercream. An easy and delicious recipe (to decorate about 10 - 12 cupcakes or cover the outside of a 6 inch / 15 cm cake)


  • 5 Egg whites (About 165 g)
  • 150 G Granulated sugar
  • 247 g Butter (softened and cut into pieces)
  • 100 g white chocolate (melted)
  • 1 tsp Vanilla
  • 1 pinch Salt


  1. Place the egg whites with the granulated sugar in a container and heat them in a double boiler over a saucepan containing a little water.
  2. Mix with a whisk and check the temperature with a candy thermometer, which should read at least 131°F / 55°C (the sugar should be completely dissolved).
  3. Pour the mixture into the bowl of a mixer fitted with the whisk attachment and beat at high speed for about 15-20 minutes until the meringue is white and has firm peaks. (Meringue should be completely cool)
  4. Lower the speed of the mixer and add the butter piece by piece, then resume high speed and mix for at least 5 minutes. (the mixture can go from liquid to grainy, so keep beating until you have a thick, smooth cream)
  5. Add vanilla, salt and melted white chocolate and mix again for 2-3 minutes.
  6. Change the whisk to a flat spatula and mix again for 2 minutes at slow speed to loosen the buttercream and remove the excess air that has been incorporated to make a smoother cream.



Leave it at room temperature to use it during the day or place it in the fridge to keep it for up to 1-2 week.
After a cold storage, it will harden and you will have to bring it back to the right temperature, either by heating it slightly in a double boiler or microwave or by leaving it outside the refrigerator. Then it will have to be whipped again to give it a creamy texture.

In the freezer:

You can freeze it in a storage box for up to 3 months.
