Directions

1. Place egg whites in a bowl; let stand at room temperature 30 minutes. Line bottoms of 3 greased 9-in. round baking pans with parchment; grease paper well.
2. Preheat oven to 350°. Place white chocolate in a small bowl. Pour boiling water over chocolate; stir with a whisk until smooth. Cool slightly.

4. With clean beaters, beat egg whites on medium speed until stiff peaks form. Fold into batter. Transfer to prepared pans.
5. Bake 20-25 minutes or until a toothpick inserted in center comes out clean. Cool in pans 10 minutes before removing to wire racks; carefully remove paper. Cool completely.
6. For frosting, place white chocolate in a small bowl. Pour boiling water over chocolate; stir with a whisk until smooth. Cool to room temperature, stirring occasionally.
7. In a large bowl, beat butter, vanilla and salt until creamy. Beat in confectioners’ sugar alternately with chocolate mixture until smooth. Spread frosting between layers and over top and sides of cake. If desired top cake with flaked coconut.
