Ingredients
  

  • 3 large egg whites
  • 1 cup + 2 tablespoons sugar (fruit/caster/fine) (225 grams)
  • cup + 1 ½ tablespoons butter (soft - cubed) (313 grams)
  • 1 teaspoon vanilla

Instructions
 

  • Either in your standup mixer bowl or a large heat safe glass bowl add the egg whites and sugar, then place it over a pot of water over medium heat and whisk until the sugar has dissolved, this will take about 15-20 minutes, you can feel between your fingers when the sugar has completely dissolved and the mixture is smooth.
  • Then with the whisk attachment beat on medium speed until the mixture is completely cool and the mixture has thickened, about 10-15 minutes, add the butter a little at a time beating continuously until completely combined, add the vanilla and beat on high to combine about 1 minute. You should then have a smooth creamy frosting. Enjoy!

Notes

If you prefer you can use granulated sugar but it will take longer for the sugar to dissolve.
Refrigerate any left over in an airtight container, it will keep for up to 5 days. It can also be frozen for up to 3 months in a freezer safe container.
