  • 4 sweet potatoes
  • 4 tbsp butter

  3. Pierce a potato with the probe of a thermometer. Set the thermometer alarm to 190F degrees for a slightly firm potato or 200F degrees for a creamier sweet potato. 

  4. They should reach your desired internal temp in 60-90 minutes. 

  5. Roast the marshmallows on a skewer, holding them over the heat of the grill.
  6. Slice open the sweet potatoes. Top with butter, cinnamon sugar and roasted marshmallows.
