Cake:
Cooking spray
1 tablespoon all-purpose flour
3/4 cup egg substitute
1/3 cup granulated sugar
1/3 cup applesauce
1 (15-ounce) can pumpkin
2 teaspoons pumpkin-pie spice
1 (18.25-ounce) package yellow cake mix
Frosting:
2/3 cup (6 ounces) tub-style light cream cheese
1 1/4 teaspoons vanilla extract
3 1/2 cups powdered sugar
Preheat oven to 350°.
Coat a 13 x 9-inch baking pan with cooking spray; dust with flour.
To prepare cake, place the egg substitute, granulated sugar, applesauce, and pumpkin in a large bowl; beat with a mixer at high speed for 1 minute. Add pie spice and cake mix, beating at high speed 2 minutes. Pour batter into prepared pan. Bake at 350° for 35 minutes or until a wooden pick inserted in center comes out clean. Cool cake completely on a wire rack.
To prepare frosting, place the cream cheese and vanilla in a large bowl; beat at medium speed until smooth. Gradually add the powdered sugar, beating just until blended. (Do not overbeat.) Spread frosting evenly over top of cake.
