Resift flour with baking powder and salt. Cream shortening with 1 cup sugar until light and fluffy. Blend in flour mixture and champagne (alternating), mixing to a smooth batter.

Beat egg white until stiff. Gradually beat in remaining 1/2 cup sugar, continuing to beat to a stiff meringue. Fold about half the meringue into the batter, mixing thoroughly with wire whip. Gently fold in remaining meringue. Turn into 2 greased and floured 9-inch layer cake pans. Bake at 350 degrees F for 25 to 30 minutes, just until cake tests done. Let stand 10 minutes then turn out on wire racks to cool.
