    Your creating a Meringue with sugar and eggs whites in a kind of backwards way in order to completely dissolve the sugar, which makes the frosting silky smooth in texture. The thickness come from beating the whites until *completely cooled*(10 minutes at md-high speed) which leaves them foamy and a bit thick like soft marshmallow, then adding the butter to finish thickening to spreading piping consistency. It won't be as thick as American buttercream, it's much more delicate (and tasty).

    You are heating the egg whites and making them stiff as you cook them so it should turn out okay if you are really use to powdered sugar this takes a little longer but soooo worth it!! Try it again!!

    The meringue should give you the proper thickness. If yours was too thin - you may not have made a stiff enough meringue.

    We tried this frosting and failed. If you don't add powdered sugar or something else, what thickens the frosting?
