A Hummingbird Cake is usually a three layer cake with frosting between each layer, the top and sides. I will admit to being motivated in large part by laziness when I adapted this Traditional Hummingbird Cake recipe to make it a Bundt cake. However, in the process I also made it a little less decadent. I replaced half of the oil with applesauce and since applesauce is sweet, I cut the sugar in half as well. It is just topped with frosting, so I only used a third as much frosting as I would if I were making a cake. If you wanted to reduce the sugar even more, you could dust the top with powdered sugar in place of the frosting and chopped pecans.
