Instructions for the meringue: 

  • Prepare a simmering water for a double boiler method. Combine the egg whites and sugar.

  • If you don’t use thermometer like me, just make sure the sugar is completely dissolved in the egg whites.
  • Remove from the heat and whisk till it reaches stiff peaks. 
  • In a separate bowl, whisk the butter till fluffy then add the shortening and keep whisking till the mixture becomes light in color and creamy.
  • Combine the butter and shortening mixture with the meringue. 

Instructions for the white chocolate: 

  • Combine the cream and chocolate in a bowl and heat up in the microwave for 30 seconds and mix well.
  • You can also do the double boiler method to melt the chocolate.

Instruction sfor the White chocolate buttercream: 

  • Add about 1/3 of the meringue to the chocolate mixture and mix them well.
  • Pour the mixture to the remaining meringue and mix them well again, then your buttercream is ready.  

Notes

  • If you live in a very humid area, replace the butter with vegetable shortening. 
  • In the fridge, in a sealed container, buttercream can be stored for up to two weeks and up to two months in the freezer. 
  • Buttercream becomes hard from the fridge, so let it sit at room temperature and whisk it till becomes smooth again.
