    6 Egg whites, 400 g Granulated sugar
  • Place the bowl onto a double boiler (a big pot filled with 2 inches of simmering water). Whisk until the egg whites are hot to the touch and you can't feel any sugar grains anymore, or the candy thermometer reads 160°F.
  • Place the bowl onto your stand mixer (or use your hand mixer) and whisk on medium-high until the egg white is stiff and cooled. The bowl has to be cold to the touch.
  • Slowly add cubed, soft butter and mix until smooth.
    230 g Butter
  • Add Vanilla extract and mix until combined.
