Wash, peel, and cut sweet potatoes into chunks or slices.
Place in medium sized stock pot and add enough water to cover the sweet potatoes by about an inch. Bring to a boil over medium high heat, then reduce heat to medium and cook until potatoes are soft and tender, about 20 minutes. Drain potatoes and transfer them to a large mixing bowl.
Add butter, cream, honey, and cinnamon to potatoes and beat with an electric mixer on medium speed until well blended, light, and fluffy. Serve warm.
