9 egg whites
3 c sifted all purpose flour
1 tsp baking powder
1/2 tsp salt
2 c sugar
9 egg yolks
2 c butter, softened
2 tsp vanilla extract
confectioner’s sugar (I skipped this part)
Warm egg whites to room temperature. Preheat oven to 350. Grease and lightly flour 10 inch tube pan. Mix flour, baking powder and salt, set aside. Beat egg whites until foamy. Gradually beat in 1 c sugar, 1/4 c at a time, beating after each addition. Continue beating until soft peaks form when beater is slowly raised. Set aside. Beat yolks with remaining c of sugar, butter, and vanilla. Once smooth, mix in the flour mixture, and resmoothen. Mix in egg white mixture carefully, until just blended. Turn into prepared cake pan. Bake 65 minutes, or until it passes the toothpick test. Let cool 15 minutes. Loosen around edges, and turn cake out of pan.
One of the ways in which this was enjoyed was moderately thin slices with peanut butter and jelly.
