Ingredients
6 large sweet potatoes, peeled and cut into chunks
1 cup granulated white sugar
½ cup packed brown sugar
2 tablespoons ground cinnamon, or adjust to taste
1 tablespoon butter, softened to room temperature
1 cup miniature marshmallows, or add more for a thicker topping
Step-by-Step Directions
Add your prepared sweet potato chunks to a large pot, cover fully with salted water, and bring the water to a rolling boil over high heat.
Lower the heat to medium-low, then let the potatoes simmer until fork-tender (about 20 minutes total) before draining all excess water.
While the sweet potatoes cook, preheat your oven to 375°F (190°C) and grease a deep casserole dish to prep for baking.
Transfer the drained sweet potatoes to a large mixing bowl, and mash with a potato masher until no large lumps remain.
Stir in the white sugar, brown sugar, cinnamon, and softened butter until everything is fully combined and smooth.
Pour the sweet potato mixture into your prepared casserole dish, spread it into an even layer, and cover the entire top evenly with marshmallows.
Bake in the preheated oven for roughly 30 minutes, until the marshmallow topping is puffed and golden brown.
