i didn't want to rate this recipe with stars because i made a lot of changes (thus a rating technically wouldn't be accurate), but i couldn't submit a review without a rating, so i'm giving it 5 stars for versatility.
i scaled the recipe down to 12 muffins, used 1 cup whole wheat and 1 cup all-purpose flour, used starfruit (carambola) pulp instead of applesauce, 1/2 cup of brown sugar, 1 1/2 cups pumpkin puree, and used ginger instead of nutmeg (didn't have any). i also added 4 tbsp of whole flax seed for a nutty texture. The muffins rose nicely, were very fluffy and not dense. They were just faintly sweet, which which i prefer (i don't have much of a sweet tooth). i used paper liners, and the only drawback was that the muffins stuck to the liners. next time i would use a non-stick spray. but overall, great recipe to start with. i've included a picture as well.
