These pumpkin muffins are definitely a fall favorite. My sister-in-law, Emily, loves everything pumpkin in the fall. One day I wanted pumpking muffins for the family, but did not have chocolate chips that I use for the standard pumpking chocolate chip muffins. Instead of giving up on the craving, I decided to find another solution. These cinnamon sugar topping on these muffins makes them extra sweet and gives them an extra kick of cinnamon and pumpkin pie spice. They get a little messy but are so worth it. You will catch yourself licking the crumbs and sugar off the plate after.
