Equipment

  • Large Mixing Bowl

Ingredients

For the Sweet Potato Mash:

  • 4 lbs sweet potatoes (peeled and cut into 2 inch cubes)
  • 1 egg
  • 1 tsp salt
  • 1 tsp vanilla
  • 1/3 cup brown sugar
  • 1/3 cup white sugar
  • 1/2 cup melted butter
  • 1/3 cup milk

For the Topping:

  • 2/3 cup brown sugar
  • 6 TBS flour
  • 6 TBS melted butter
  • 1 1/2 cup chopped pecans
  • 3-4 cups about 1/2 package mini marshmallows

Instructions

For the Sweet Potato Mash:

  • Bring a large pot of water to boil and add the sweet potatoes. Cook them in the water for about 20-25 minutes until they are soft (and can be pierced with a fork). Drain out the water.
  • Preheat the oven to 375 degrees Fahrenheit.
  • Mash the sweet potatoes in a large bowl to desired consistency. (I like mine with a little texture, decide how smooth you want them).
  • Add in the egg, salt, vanilla, brown sugar, white sugar, melted butter and stir it all to combine.
  • Scoop the mixture into a 9x13 in baking dish.

For the Topping:

  • In a medium sized bowl, combine the brown sugar, flour, butter and chopped pecans and stir well.
  • Sprinkle the mixture evenly over the top of the sweet potatoes.
  • Bake the dish uncovered for 20 minutes, or until the pecans are caramelized.
  • Sprinkle marshmallows evenly over the top of the sweet potatoes.
  • Bake for another 3-5 minutes or until the marshmallows are puffy and golden brown.
  • Serve hot.
