You won't believe this cake came from a box! It's luxuriously moist, and the pumpkin gives it a lovely orange fall color. Our favorite variation of this recipe is Apple Spice Cake, made by adding 3 apples (cored, peeled, and chopped in food processor) to the batter, as well as adding extra cinnamon and pumpkin pie spice. We also love topping this cake with a delightful powdered sugar glaze or cream cheese frosting!
