apple cake recipe

I had half a dozen apples in the fridge. The recipe was very simple, used only one egg, so easy to substitute the egg. The cake came out very well. It was very moist and fluffy, but over the top sweet. The original recipe used 1 cup sugar and the apples I used were sweet too, so the cake became very sweet. So I have changed the recipe to 3/4 cup of sugar. I was wondering what to do with the cake, then got this (wonderful) idea. I was not sure whether it would work, but I was totally surprised and happy with the result. Check the My Notes section to see what I did. But this apple cake recipe is definitely a keeper for its easy prep and unbelievably moist and fluffy texture for a vegan cake.
