A majority of the ingredients in this recipe are fairly healthy, as far as muffin recipes go. The only ingredient you would need to swap is the sugar. For a healthy pumpkin muffin recipe, swap the granulated sugar with coconut sugar. The muffins will turn out a little darker but they'll taste just as good! As for the coating, coconut sugar won't stick as well as granulated sugar. Instead, leave out the cinnamon sugar coating and opt for pumpkin seeds. Sprinkle some on top of the muffins before baking for a little extra crunch.
