Vegan banana and chocolate muffins

I used the recipe from yesterday's blip. They looked really good. The chocolate on the top was purely for decoration. There is none in the cakes. They were not very sweet so I dribbled some icing on them like you get on a Danish pastry.
I am not vegan but friends are.
I think more tweaking of the recipe is needed before you would not be able to tell they were vegan.
