Angel Food Cake

This is one of my son's favorite cake; found this recipe at Allrecipes.com and I decided to give it a try since then, this very moist and light angel food became a family's favorite at my house. Since the snow is still not melted, I am pretty sure that there will be no school again tomorrow! I will make one for my son tomorrow.
For a fatless dessert, serve angel food cake topped with fresh fruit.

Ingredients:

• 2 cups egg whites
• 1/4 teaspoon salt
• 1 1/4 teaspoons cream of tartar
• 1 1/4 cups white sugar
• 1 1/4 cups confectioners' sugar
• 1 1/4 cups cake flour
• 1/4 cup unsweetened cocoa powder
• 1 1/4 teaspoons vanilla extract

Procedures:
Preheat oven to 325 degrees F (165 degrees C).

In a medium bowl, mix confectioners' sugar, cake flour, and cocoa. Sift together 2 times, and set aside.

In a clean large bowl, whip egg whites, salt, and cream of tartar with an electric mixer on high speed until very stiff. Fold in white sugar 2 tablespoons at a time while continuing to mix. Fold in flour mixture, a little at a time, until fully incorporated. Stir in vanilla. Pour into a 10 inch tube pan.

Bake at 325 degrees F (165 degrees C) for approximately 1 hour, or until cake springs back when touched.
