Begin by peeling and chopping the sweet potatoes. Boil until tender, then mash them.

In a mixing bowl, combine yeast, sugar, and warm milk. Let sit until bubbly, then add melted butter, mashed sweet potatoes, flour, and salt.

Knead the dough on floured surface until smooth and elastic, about 5-7 minutes.

Place the kneaded dough in a greased bowl and let it rise for about 1 hour.

Punch down the dough and divide it into equal pieces. Shape into balls.

Cover the shaped rolls with a towel and let rest for 30 minutes.

Preheat oven to 350°F. Bake the rolls for approximately 25 minutes.

Let the rolls cool slightly and serve warm.
