Creamy Birch Syrup Frosting


2/3 cup birch syrup
3 egg whites at room temperature


  1. Pour birch syrup into a medium sauce pan.
  2. Heat over medium heat, without stirring, until syrup reaches 240° F on a candy thermometer.
  3. Meanwhile, beat egg whites with mixer on high speed, until soft peaks form.
  4. As soon as the birch syrup reaches 240°F, gradually pour it into the whipped egg whites in a slow, steady stream while continuing to beat with the mixer on high speed.
  5. Once all the syrup is incorporated and the frosting returns to soft peaks, the frosting is ready.
