Preheat oven to 350 degrees. Prepare two 8” or 9” cake pans with parchment on the bottom and spray with cooking release spray. Put all dry ingredients in a mixer bowl and mix on low until blended. Mix all the wet ingredients and add to the dry and blend until smooth. Add apples and if you like, nuts. Blend until smooth. Pour into pans and bake for 25 to 30 minutes.
