Cinnamon-Apple Angel Food Cake

Directions

1. Place egg whites in a large bowl; let stand at room temperature for 30 minutes. Sift confectioners' sugar and flour together twice; set aside.
2. Add cream of tartar, vanilla and almond extract and salt to egg whites; beat on medium speed until soft peaks form. Gradually add granulated sugar, about 2 tablespoons at a time, beating on high until stiff glossy peaks form and sugar is dissolved. Gradually fold in flour mixture, about 1/2 cup at a time.
3. Gently spoon into an ungreased 10-in. tube pan. Cut through the batter with a knife to remove air pockets. Bake on the lowest oven rack at 375° for 35-40 minutes or until lightly browned and entire top appears dry. Immediately invert pan; cool completely, about 1 hour.
4. Run a knife around side and center tube of pan. Remove cake to a serving plate.
5. For glaze, melt butter in a small saucepan. Stir in the confectioners' sugar and cinnamon until blended. Add apple juice slowly until glaze is thin enough to achieve a drizzle consistency. Drizzle over cake.
