1 c. shortening
2 c. sugar
1/2 tsp. salt
2 tsp. vanilla
4 eggs
3 1/3 c. cake flour
3 tsp. baking powder
1 1/8 c. milk
1 tsp. grated orange rind
2 tbsp. orange juice
1 to 1 1/2 oz. chocolate
1/4 tsp. baking soda
2 tbsp. hot water

Cream shortening, sugar, salt, vanilla, and 1 egg until light. Sift flour and baking powder. Add flour and milk and mix thoroughly but quickly. Divide batter into 3 equal parts.

To part one: Fold in 2 egg whites, beaten stiff.

To part two: Add 2 egg yolks, beaten thick, orange juice and rind.

To part three: Add melted chocolate, remaining egg, and soda dissolved in hot water. Pour each mixture into a well-greased and floured 9-inch layer pan. Bake 20-25 minutes at 375 degrees. Put together with Magic Icing, having chocolate layer at bottom, white in the middle and orange on the top.

MAGIC ICING:

2 c. superfine sugar
1/2 tsp. cream of tartar
1/4 tsp. salt
5 tbsp. hot water
2 egg whites
1 tsp. vanilla
1/2 tsp. baking powder

Mix sugar, cream of tartar, salt and water and stir until sugar dissolves. Bring to a full rolling boil. Pour onto unbeaten egg whites, beating constantly (electric mixer best) and continue beating at medium speed until icing peaks. Add vanilla and baking powder, mix and let cool before spreading. Half this quantity is enough for a 2-layer, 8-inch cake.
