Equipment

  • large pot or dutch oven
  • large mixing bowl
  • Hand mixer
  • small bowl
  • casserole dish

Ingredients

  • 6 large sweet potatoes washed, peeled, and cut into cubes
  • ½ cup butter melted
  • ½ cup milk half-and-half, or heavy cream
  • ½ cup brown sugar packed
  • 1 teaspoon ground cinnamon
  • ½ teaspoon salt

Topping

  • ½ cup butter softened
  • ½ cup brown sugar packed
  • ½ cup all-purpose flour
  • 1 teaspoon ground cinnamon
  • ¾ cup pecans chopped
  • 1-2 cups mini marshmallows

Instructions

  • Preheat oven to 375F. Grease a 9x13-inch baking dish with non-stick cooking spray.
  • Bring a large pot of water to a boil and add the cubed sweet potatoes. Boil until fork-tender (make sure they’re very soft so they will whip easily), about 15-20 minutes. Drain the water and transfer the sweet potatoes to a large bowl.
  • Add the melted butter, milk/cream, brown sugar, cinnamon, and salt. Whip the sweet potatoes with an electric mixer on medium speed until smooth.
  • Spread the whipped sweet potatoes into the prepared baking dish.
  • In a medium mixing bowl, cut the butter into the brown sugar, flour, and cinnamon until crumbly. Mix in the chopped pecans. Sprinkle the mixture all over the top of the whipped sweet potatoes.
  • Bake the sweet potato casserole at 375F for 12 minutes until hot. Remove from the oven and sprinkle the mini marshmallows around the edges of the casserole. Return to the oven and bake for 5 minutes until the marshmallows are golden brown (watch closely so the marshmallows don’t burn!).
  • Serve the casserole hot.
