My friend Stephanie was craving white cake with white icing.  I made the following cake for her and it was a hit!  The icing tastes just like marshmallows!

Marshmallow Icing

2 egg whites                                                1/3 cup water

1 pinch salt                                                  ½ tsp. cream of tartar

1 ½ cups white sugar                                   1 tsp. vanilla extract

1 box Pillsbury White Cake Mix                      ½ tsp. vanilla extract

Mix cake mix as instructed on box, but add ½ tsp. vanilla extract.  Cook as directed on package.  Cool cake and make icing as follows.  In the top of a double boiler, combine egg whites, pinch of salt, white sugar, water and cream of tartar.  Beat 1 minute.  Cook over boiling water beating constantly for 7 minutes or until the icing makes firm peaks.  Remove from the heat and add the vanilla.  Beat until able to spread.  Note:  You can add coloring with the ingredients.  You can also use another flavoring in place of the vanilla.
