Grease and flour two 9″ cake pans. Sift together dry ingredients, sugar and spices. Add shortening, buttermilk, and bananas; mix to dampen. Beat 2 minutes with an electric mixer on low speed. Add eggs, beat 1 minute. Bake in prepared pans at 350 degrees for 40 minutes or until cake tests done with a toothpick. Cool cake completely on wire racks. To make frosting, combine egg whites, water, sugar and salt in a six cup double boiler and beat slightly to mix. Place over rapidly boiling water and beat for 7 minutes on high speed. Remover from heat and add vanilla–beat 1 to 2 minutes more. Frost cake, placing banana slices on top of the frosting between the layers. Melt the baking chocolate and butter together in the microwave on medium heat. Drizzle chocolate mixture over the top and down the sides of the cake for decoration.
