Ingredients

Sweet Potatoes

  • 5 pounds sweet potatoes, (peeled and cut into 1” pieces)
  • 4 tablespoons unsalted butter, (½ stick)
  • ½ cup brown sugar
  • ½ teaspoon salt
  • 1 teaspoon pure vanilla extract
  • 1.5 teaspoon ground cinnamon
  • ¼ teaspoon ground nutmeg
  • ½ cup heavy cream
  • 1 small egg, optional, but helps the structure
  • 2 cups mini marshmallows

Brown Sugar Streusel Topping

  • 1 cup all-purpose flour
  • ¼ teaspoon salt
  • 1 teaspoon ground cinnamon
  • 6 tablespoon unsalted butter, room temperature
  • ¼ cup dark brown sugar, (packed)

Instructions

Streusel Topping

  • Mix flour, salt, ground cinnamon, butter and dark brown sugar with a fork until a desired crumble texture is achieved. Add more sugar if you want finer crumbs.

Sweet Potatoes

  • Bring large pot with water to boil over high heat. Add sweet potato pieces and cook until fork tender, about 15 to 20 minutes.

  • Add butter, brown sugar, salt, vanilla extract, nutmeg and cinnamon and combine
  • Add heavy cream and 1 small egg (optional), combine for another minute until well incorporated.
  • Transfer sweet-potato mixture to a 2-quart baking dish. Top with 2 cups of mini marshmallows and set aside.
  • Preheat oven to 375 F.

Final Assembly

  • Top the sweet potato mixture and marshmallows with the prepared crumble topping.
  • Bake at 375F until center is warmed through and marshmallows and topping is lightly browned, 30 minutes.
