  • Total Time: 50 minutes
  • Yield: 8 servings

Ingredients

Sweet Potato Base

  • 4 1/2 cups Cooked and mashed sweet potatoes (from 4 sweet potatoes)
  • 2 Large eggs, beaten
  • 3/4 cup apple butter
  • 1/2 cup heavy whipping cream
  • 2 tsp vanilla extract
  • 1/2 tsp ground nutmeg
  • 3/4 cup light brown sugar, divided
  • 1/2 cup unsalted butter, melted and divided
  • 1 1/2 tsp kosher salt, divided

Topping

  • 15 large marshmallows
  • 3/4 cup pecan halves
  • 3/4 cup unsweetened coconut flakes
  • 1/3 cup all-purpose flour
  • 1/2 tsp ground cinnamon

Instructions

  1. Preheat the Oven: Set your oven to 350°F (175°C) to warm up while you prepare the sweet potato mixture.
  2. Make the Sweet Potato Mixture: In a large bowl, combine the mashed sweet potatoes and stir until fully smooth. Add the beaten eggs, apple butter, heavy cream, vanilla extract, ground nutmeg, 1/4 cup of brown sugar, 1/4 cup of melted butter, and 1 teaspoon of kosher salt. Stir thoroughly until all ingredients are well blended and the mixture is silky smooth.
  3. Transfer to Baking Dish: Spoon the sweet potato mixture into an ungreased 10-inch cast-iron skillet or a similar-sized casserole dish, and smooth the surface evenly with a spatula. Arrange the marshmallows evenly on top of the sweet potatoes.
  4. Prepare the Topping: In a medium bowl, mix together the pecan halves, unsweetened coconut flakes, all-purpose flour, ground cinnamon, remaining 1/2 cup brown sugar, and 1/2 teaspoon kosher salt. Add the remaining 1/4 cup melted butter and stir until the topping mixture holds together in clumps.
  5. Top the Casserole: Scatter the pecan and coconut crumble mixture evenly over the marshmallows on the sweet potato base.
  6. Bake: Place the skillet or casserole dish in the preheated oven. Bake for about 25-30 minutes or until the casserole is hot and bubbling around the edges, the marshmallows are golden brown on top, and the center is set and no longer wet.
  7. Serve Warm: Remove from the oven and let it cool slightly before serving to enjoy the comforting layers of texture and flavor.

Notes

  • Use room temperature ingredients for easier mixing and smoother texture.
  • You can prepare the sweet potatoes ahead of time and refrigerate before assembling the casserole.
  • To avoid browning too fast, cover with foil for the first 20 minutes of baking, then uncover to brown the marshmallows and topping.
  • For a healthier variation, consider using light cream and reducing sugar slightly.
  • Cast-iron skillet helps achieve better heat distribution and presentation but a casserole dish works well too.
