-Separate the eggs. Beat the whites with the cream of tartar until stiff. Gradually beat in 1/2 cup of the sugar.
-Sift the remaining sugar, cocoa, and flour together. Beat the egg yolks until thick and fold the flour mixture into them. Stir in vanilla. (The egg yolk mixture will be very stiff). Carefully fold the egg yolk mixture into the beaten egg whites. Evenly spread the batter into the prepared pan.
