Equipment

  • 1 Pot
  • 1 Stove
  • 1 Knife
  • 1 Large Bowl
  • Measuring Cups
  • Measuring Spoons
  • 1 9x11 Baking Dish
  • 1 Silicone Spatula
  • 1 Potato Masher

Ingredients

  • 8 Sweet potatoes
  • 2 tablespoons Salted butter
  • ½ cup Brown sugar
  • 1 teaspoon Cinnamon
  • 4 cups Mini marshmallows

Instructions

  • Steam sweet potatoes for 20 minutes or until fork tender.
  • Remove from the steamer basket, let rest for 10 minutes, then peel the skins off and place the peeled sweet potatoes into a large bowl.
  • Add the salted butter, brown sugar, and cinnamon to the bowl. Using a potato masher, mash the sweet potatoes until smooth.
  • Preheat the broiler on high.
  • Spray non-stick cooking spray into an oven-safe 9x11 rectangular baking dish. Pour the mashed sweet potatoes into a dish. Top with mini marshmallows.
  • Broil on high for 1 minute or until marshmallows are golden brown. Serve immediately.

Notes

  • Roast the Sweet Potatoes: Roasting sweet potatoes instead of boiling them brings out their natural sweetness and keeps the texture smooth. You can roast the sweet potatoes hole (make sure to prick the skin with the tines of a fork a few times so steam can release) then follow the same steps to peel the skin off.
  • Boiling Sweet Potatoes: If you don't want to steam or roast the sweet potatoes you can peel and dice the sweet potatoes. I don't like this method as sweet potatoes are harder to peel.
  • Toast the Marshmallows Evenly: Place the dish on the middle rack of your oven for even browning, and watch closely to avoid burning.
  • Add a Crunchy Topping: If you love texture, sprinkle chopped pecans or crushed graham crackers under the marshmallows for a delightful crunch.
  • Balance the Sweetness: Add a pinch of salt to the sweet potato mixture to enhance the flavors and keep it from being overly sweet.
