This is one of the best cake recipes I've found. It is from the Better Homes and Gardens Cook book. I usually make this with peanut butter frosting, but have come to realize that it is still delicious with no frosting at all. Unlike most things in my blog this dessert is fat free and only has about 150 calories per serving.
Chocolate Angel Food Cake
1 1/2 c. Egg whites (approx 12 eggs)
1 1/2 c. sifted powdered sugar
1/4 c. cocoa powder
1 c. sifted cake flour or all purpose flour
1 1/2 t. cream of tartar
1 t. vanilla (almond extract is great too)
1 c. granulated sugar
Allow egg whites to sit at room temperature in mixing bowl for 30 minutes. Meanwhile, sift powdered sugar, cocoa, and flour together three times. Set aside
Add cream of tartar and vanilla to egg whites. Beat on medium speed until soft peaks form. Gradually add granulated sugar, beating until stiff peaks form.
Sift 1/4 of the flour mixture over beaten egg whites; fold in gently. Repeat in fourths. Pour into
ungreased 10" tube pan. Gently cut through batter to remove air pockets.
Bake on lowest rack at 350 degrees for 35-45 minutes or until top springs back when lightly touched. Immediately invert cake to cool.
