  • Baking Sheet
  • Kitchen Torch


Sweet Potato Casserole

  • 5 large sweet potatoes washed and pat dry
  • 1/2 cup brown sugar
  • 1/4 cup salted butter
  • 1/2 tsp salt
  • 2 tbsp heavy cream


  • Preheat the oven to 425-degrees Fahrenheit
  • Rinse and pat dry the potatoes.
  • Line a baking sheet with foil and place the potatoes on the foil to bake.
  • Bake until tender for about 50 minutes. You want them to be extra soft. 
  • Cut them open and scoop out the sweet potato and place in a bowl, leaving the skin behind. 
  • Mash the sweet potatoes with butter, sugar, salt, and heavy cream while they’re hot. 
  • Mash until the texture is smooth or how you like it.
  • Spread the mashed sweet potatoes into a casserole dish.
  • Spread the homemade marshmallow fluff over the mashed sweet potatoes. 
  • Using a kitchen torch, torch the marshmallow fluff until it’s toasty! 


You can also use marshmallows for this recipe. Simply add an even layer of marshmallow over the top of the sweet potatoes (once the casserole is done) and place in a 350-degree oven for 5 minutes until the marshmallows are gooey and toasted!
This would replace the marshmallow fluff but still just as delicious!
