Description

Ingredients
•
2 1/2 pounds sweet potatoes
•
1 teaspoon vegetable oil, or as needed
•
3/4 cup dark brown sugar
•
1/2 cup heavy whipping cream
•
1/4 cup melted butter
•
1/4 teaspoon ground cinnamon
•
1/4 teaspoon salt
•
1/4 cup rolled oats
•
2 teaspoons dark brown sugar
•
1 tablespoon all-purpose flour
•
1/8 teaspoon ground cinnamon
•
2 tablespoons cold butter
•
2 cups miniature marshmallows
Directions
1
Preheat the oven to 400 degrees F (200 degrees C).
2
Rub sweet potato skins with vegetable oil; place on a baking sheet.
3
Bake in the preheated oven until tender, about 1 hour; cool slightly. Reduce oven temperature to 350 degrees F (175 degrees C).
4
Cut sweet potatoes in half; scrape flesh into a large bowl when cool enough to handle. Discard skins. Beat sweet potatoes with an electric mixer until smooth.
5
Transfer 6 cups mashed sweet potatoes to a separate large bowl. Add ¾ cup brown sugar, cream, ¼ cup melted butter, ¼ teaspoon cinnamon, and salt; beat to combine. Pour sweet potato mixture into an 8x8-inch baking dish.
6
Place rolled oats into the bowl of a food processor or blender; pulse until finely ground. Combine oats, 2 tablespoons brown sugar, flour, and ⅛ teaspoon cinnamon in a bowl; cut in 2 tablespoons cold butter with a pastry blender or fork until crumbly. Sprinkle evenly over sweet potato mixture.
7
Bake in the preheated oven until sweet potatoes are heated through and oatmeal streusel is lightly browned, 70 to 80 minutes. Remove from oven, sprinkle immediately with marshmallows, and let stand until marshmallows are melted, about 10 minutes.
