   Preheat oven to 375 degrees; lightly grease two 9-inch
   layer pans.  Sift flour once before measuring, then sift 3
   times with baking powder, salt and baking soda.  Cream
   butter until soft and smooth; gradually add sugar, creaming
   until light and fluffy.  Add beaten egg yolks, then melted
   chocolate.  Add milk alternately with dry ingredients,
   beating until smooth after each addition.  Continue beating
   for two minutes.  Fold in flavoring and stiffly beaten egg
   whites.  Turn into prepared pans and bake for about 30
   minutes.
   
   Turn out onto a wire rack to cool.  Split layers in half
   horizontally.  To prepare frosting, cream butter until
   soft; slowly stir in 2 cups sugar and the salt.  Add
   additional sugar alternately with cream, beating thoroughly
   after each addition until creamy and smooth.  Stir in
   walnuts with the last of the sugar.  Beat in maple
   flavoring.  Additional cream may be added to give frosting
   proper spreading consistency.  Spread between layers, then
   frost top and sides of cake.
