Sweet Potato Layer:

Assembling the Casserole:

  1. Add half of the mashed sweet potatoes mix to the prepared pan, distribute evenly and smooth the top with a spatula.
  2. Sprinkle half of the Cinnamon Filling mixture on top of the mashed potatoes.
  3. Add the remaining sweet mashed potato filling, distribute evenly and smooth the top with a spatula.
  4. Sprinkle the Pecan Filling mixture on top of the mashed potatoes.
  5. Sprinkle the mini marshmallows if using.
  6. Sprinkle the remaining Cinnamon Filling mixture on top.


  1. Bake for 30 minutes, until the filling is hot and the topping has browned.

  3. Serve warm.
