Ingredients

Servings:-1+
450 g unsalted butter (cold)
50 ml water
170 g sugar
150 g egg whites
10 g vanilla sugar
¼ tsp salt
Metric
Imperial

Step 1/4

  • 50 ml water
  • 150 sugar

Add water and part of the sugar to a saucepan over medium-low heat. Stir well. Use a candy thermometer to check the temperate and remove from heat once the syrup reaches 120°C/250°F.

Step 2/4

  • 150 egg whites
  • 20 sugar
  • 10 vanilla sugar
  • ¼ tsp salt

As the sugar syrup heats up, add egg whites to the bowl of a stand mixer and mix on high speed for approx. 1 min. or until foamy. Reduce mixing speed to low and slowly stream in the remaining sugar , vanilla sugar, salt. Then increase the mixing speed to high for approx. 1 min. to combine well. Reduce speed to low and continue to mix for approx. 2 min. more.

Step 3/4

Slowly stream in the still-hot sugar syrup and increase the mixing speed to medium-high. Continue mixing until the mixture cools down to room temperature, approx. 10 min. Transfer the bowl to the fridge and chill for approx. 30 min.

Step 4/4

  • 450 unsalted butter (cold)

Return the bowl to the stand mixer and turn to medium-low speed. Slowly add the chilled, cubed butter. Increase the mixing speed to high. The mixture will look split but continue mixing until it comes together as a smooth buttercream. This can take between approx. 10 – 40 minutes depending on the temperature. Once done, use immediately or refrigerate in an airtight container. Enjoy!
