Preheat oven to 350F. Line muffin pan with paper liners.
Fold the dry ingredients into the wet ingredients until completely mixed.
Dip each muffin top in the melted butter, then dip in the cinnamon/sugar mixture.
Allow to cool and enjoy!
*For an egg-free version, use 3 Tbsp aquafaba.
These would also be great with a cream cheese frosting.
