Swiss Meringue Buttercream

Nothing smooths over a cake or pipes onto cupcakes as beautifully as this buttercream will. I love how it melts in my mouth. It is like satin without the gritty taste or feel of confectioners sugar. It’s a rich and luscious dream.

  • 2/3 cup egg whites 150 g
  • 1 1/4 cups sugar 250 g
  • 1 1/2 cups unsalted butter, cut into 1 tbl. cubes or slices 340 g or 3 cubes
  • pinch of salt
  • 2 teaspoons vanilla


  • 1/2 cup seedless strawberry puree


  1. In a very clean bowl of an electric mixer, add egg whites and sugar.  Place over a simmering pot of water, stirring constantly until temperature reaches 160 degrees F.  Rub a small amount of the mixture between two fingers to make sure the sugar is dissolved.  Remove from heat.  Using the whisk attachment, beat until the mixture is a thick meringue and the bottom of the bowl is cool to the touch.  The bowl must be cool before adding the butter.
  2. Replace the whisk with the paddle attachment.  With the mixture on medium-low speed add butter once slice at a time until all of the butter has been incorporated.  The mixture should be silky smooth and thick.  The mixture may begin to look curdled, keep mixing until it is smooth.  This can take 10 minutes or so.  Mix in salt and vanilla.  Add strawberry puree, if using.  Once puree is added keep mixing until mixture is silky again.
