Chocolate Angel Cake

1-1/2 cups confectioners' sugar
1 cup cake flour
1/4 cup baking cocoa
1-1/2 cups egg whites (about 10)
1-1/2 teaspoons cream of tartar
1/2 teaspoon salt
1 cup sugar

Frosting:
1-1/2 cups heavy whipping cream
1/2 cup sugar
1/4 cup baking cocoa
1/2 teaspoon salt
1/2 teaspoon vanilla extract
Chocolate leaves, optional

Sift together confectioners' sugar, flour and cocoa three times; set aside. In a mixing bowl; beat egg whites, cream of tartar and salt until soft peaks form.

Add sugar, 2 tablespoons at a time, beating until stiff peaks form. Gradually fold in cocoa mixture, about a fourth at a time.

Spoon into an ungreased 10-in. tube pan. Carefully run a metal spatula or knife through batter to remove air pockets. Bake on the lowest oven rack at 375° for 35-40 minutes or until the top springs back when lightly touched and cracks feel dry.

Immediately invert pan; cool completely. Run a knife around edges and center tube to loosen; remove cake. In a mixing bowl, combine the first five frosting ingredients; cover and chill for 1 hour.

Beat until stiff peaks form. Spread over the top and sides of cake. Store in the refrigerator. Garnish with chocolate leaves if desired. Makes 12-16 servings.
