Zucchini Carrot Spice Cake

Directions

• In a large bowl, combine the first six ingredients. Gradually add the buttermilk, applesauce, carrots, zucchini and vanilla. In a small bowl, beat egg whites until soft peaks form; gradually beat in sugar, 1 tablespoon at a time, until stiff peaks form. Gently fold into batter.
• Pour into a 13x9-in. baking dish coated with cooking spray. Bake at 350° for 30-40 minutes or until a toothpick inserted in the center comes out clean. Cool on a wire rack.
• For frosting, in a large bowl, beat the cream cheese, marshmallow creme, orange juice and vanilla just until combined. Frost cake.
