Preheat oven to 350 degrees and oil your bundt pan. This recipe is 1/4 of Vegetarian Mamma's original. I used a Wilton's Copper Retro Round Fluted 6" Pan, which is only 2 1/2 in. deep and holds approximately 3 cups of batter.
In a large batter bowl, combine oil, applesauce, egg and sugar. Whisk together, and set aside.
In a small bowl, combine flour, baking soda, salt and cinnamon. Whisk to fully blend.
Thinly slice and quarter apples of your choice. VegetarianMamma prefers Granny Smith while I prefer Gala apples. The apples do not need to be peeled, but you may do so if you wish. Add sliced and quartered apples and cinnamon chips to the dry ingredients.
Add wet ingredients to dry and thoroughly combine. The batter will be very thick. Allow to rest while preheating the oven.
Bake at 350 degrees for 35 minutes. (This is shorter than VegetarianMamma's recipe as I'm using a smaller pan. Allow cake to cool before removing from pan. Serve with a coating of powdered sugar or a simple glaze of your preference. It's tasty with ice cream too!
