Bake sweet potato until tender, or use the left over one from dinner last night. Remove skin (eat or feed to dog) and place into a blender or food processor with the date(s) and cinnamon. Blend until smooth. You can add a splash or two of water to thin it out to desired constancy.
Scoop out and eat right away or place in the fridge to firm up a bit.
Optional but lovely. Add some coconut cream on top with some chopped nuts. A scoop of nut butter or even some chopped up fruit would be nice. Also great as a oatmeal or plain yogurt mix in.
