Clean, peel, and dice sweet potatoes. Add them to a 6-quart stock pot and fill with water two inches above the sweet potatoes.
Boil the sweet potatoes on medium-high heat until softened.
Using a strainer, drain the sweet potatoes and place them in a mixing bowl. Allow them to cool for about 15 minutes.
Add all ingredients to the mixing bowl with the sweet potatoes and blend until smooth using an immersion hand blender or food processor.
Place the sweet potato mixture in a 13 X 9 non-stick baking pan. Set aside.
