Wash sweet potatoes and prick several times all over with a fork.
Place in a microwave on top of a paper towel and cover with another paper towel. Cook on high for 5 minutes (may need more depending on strength of microwave and thickness of potato).
Turn the potatoes over and cook for another 5 minutes. Remove potatoes and test for softness. If not soft, cook for 1 to 2 minutes more. Wrap potatoes in aluminum foil and allow to cool, 1 to 2 minutes.
Slice them open and add butter, honey, cinnamon, and salt. Mash the soft flesh with a fork.
