Beat until whites form very stiff peaks.
Pour egg yolk mixture gradually over beaten whites, gently folding with rubber scraper just until blended.
Pour into un-greased pan.
Bake loaf cake at 325° (slow mod.) for 50 to 55 min.; bake square cake at 350° (mod.) for 30 to 35 min., until top springs back when touched lightly.
Invert, supporting pan on clip clothespins, until cool.
