Peel and dice your sweet potatoes.
Place the sweet potatoes in a large stockpot and cover them with cold water, 2 inches over the top of the potatoes. Heat over medium high heat.
Bring to a boil. Then reduce the temperature to a simmer, and simmer until the potatoes are fork tender. About 10 to 15 minutes.
Add the butter, and cream to a stock pot over medium low heat while the potatoes are cooking. Let the butter melt and remove it from the heat.
Once tender, drain the potatoes and lay them out on paper towels to get the excess water off, for about 5 minutes.
Add the sweet potatoes to a large bowl, and add the butter and cream mixture over the potatoes.
Add in the salt, pepper, and chipotle powder.
Mash the potatoes until they reach your desired consistency.
Taste, and adjust the seasonings as necessary, to your preferences.
