Pumpkin Angel Food Cake

Directions

1. In a large bowl, combine the pumpkin, vanilla, cinnamon, nutmeg, cloves and ginger. Prepare cake mix according to package directions. Fold a fourth of the batter into pumpkin mixture; gently fold in the remaining batter. Gently spoon into an ungreased 10-in. tube pan. Cut through batter with a knife to remove air pockets.
2. Bake on the lowest oven rack at 350° for 38-44 minutes or until top is golden brown and cake springs back when lightly touched and entire top appears dry. Immediately invert pan; cool completely, about 1 hour.
3. Run a knife around side and center tube of pan. Remove cake to a serving plate. Garnish each slice with 1 tablespoon whipped topping; sprinkle with cinnamon if desired.
