Begin by peeling your sweet potatoes completely and cutting them into even chunks, about 1-inch thick.

Place the prepared sweet potatoes in a large pot and cover them with cold, salted water, then bring to a boil.

Once fork-tender, carefully drain the sweet potatoes and let them sit in the pot for an additional 2-3 minutes.

Using a potato ricer or hand masher, thoroughly mash the sweet potatoes in a large mixing bowl.

Warm your half-and-half (or milk) and butter until melted, then mix into the mashed sweet potatoes.

Transfer the creamy mashed sweet potatoes to a serving bowl and sprinkle optional cinnamon on top for garnish.
