Ingredients

Scale
  • 4 large sweet potatoes, peeled and cubed
  • 1/2 cup brown sugar
  • 1/2 cup unsalted butter, melted
  • 2 large eggs
  • 1/2 cup heavy cream
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt

Topping:

  • 1/2 cup all-purpose flour
  • 1/2 cup brown sugar
  • 1/4 cup unsalted butter, melted
  • 1/2 cup chopped pecans
  • 1 1/2 cups mini marshmallows

Instructions

  • Preheat oven to 350°F (175°C) and grease a 9x13-inch baking dish.
  • Boil the sweet potatoes in a large pot until fork-tender, about 15-20 minutes. Drain and transfer to a large mixing bowl.
  • Mash the sweet potatoes, then mix in brown sugar, melted butter, eggs, heavy cream, vanilla extract, and salt until smooth.
  • Spread the sweet potato mixture evenly in the prepared baking dish.
  • In a separate bowl, combine flour, brown sugar, melted butter, and chopped pecans to create a crumble topping. Sprinkle evenly over the sweet potatoes.
  • Bake for 25-30 minutes, then top with marshmallows and bake an additional 10 minutes or until the marshmallows are golden brown.
  • Let it cool for a few minutes before serving.

Notes

  • You can prepare the sweet potato mixture a day ahead and store in the fridge. Add the toppings just before baking.
  • Feel free to adjust the sweetness to your preference or add spices like cinnamon or nutmeg for extra warmth.
