Ingredients

Sweet Potato Mixture

  • 4 cups sweet potatoes, peeled and cubed

  • ½ cup granulated sugar

  • ½ cup packed brown sugar

  • ½ cup unsalted butter, melted

  • ¼ cup milk

  • 2 large eggs

  • 1 tsp vanilla extract

  • ½ tsp ground cinnamon

  • ¼ tsp ground nutmeg

  • ¼ tsp salt

Topping

  • 1 cup mini marshmallows

  • ½ cup chopped pecans

  • ¼ cup packed brown sugar

  • ¼ cup unsalted butter, melted


Directions (7 Steps)

1. Preheat the Oven

Preheat your oven to 350°F (175°C). Grease a 3-quart baking dish or casserole dish to keep the mixture from sticking.


2. Cook the Sweet Potatoes

Bring a large pot of water to a boil. Add the cubed sweet potatoes and cook until fork-tender, about 15–20 minutes. Drain and let cool slightly so the eggs don’t scramble later.


3. Mash the Sweet Potatoes

Transfer the cooked sweet potatoes to a large bowl. Use a potato masher or hand mixer to mash until smooth and creamy.


4. Mix the Filling

Add granulated sugar, brown sugar, melted butter, milk, eggs, vanilla, cinnamon, nutmeg, and salt to the mashed sweet potatoes. Mix until smooth, thick, and fully combined.


5. Fill the Baking Dish

Pour the sweet potato mixture into your prepared baking dish. Smooth the top evenly using a spatula so the topping cooks uniformly.


6. Make and Add the Topping

In a medium bowl, combine mini marshmallows, chopped pecans, brown sugar, and melted butter. Stir well, making sure everything is coated.
Sprinkle the mixture evenly over the sweet potato layer.


7. Bake and Serve

Bake for 30–35 minutes, or until the topping is golden brown and the marshmallows are lightly toasted.
Let cool for 5 minutes, then serve warm alongside your holiday favorites.
