Ingredients

For Sweet Potatoes

3 1/2 lbs sweet potatoes
1/3 cup salted butter
2/3 cup light brown sugar packed
3/4 cup heavy whipping cream
1 tbsp vanilla extract
1 tsp ground cinnamon
1/4 tsp ground nutmeg

For the Crumble Topping

1/2 cup all purpose flour
6 tbsp light brown sugar packed
1/4 cup old fashioned oats
1/2 tsp ground cinnamon
1/8 tsp ground nutmeg
4 tbsp salted butter melted
Marshmallows for topping 6 rows of 4 cover the whole pan

Instructions

For the Potatoes

Fill a large 8 qt pot with sweet potatoes and water about an inch higher than potatoes. Bring to a boil over high heat. While the potatoes are boiling, reheat the oven to 350 F. Grease a 9x13" casserole dish. Cook until fork tender, about 20-30 minutes, depending on the size of the potatoes. Completely drain potatoes and place back into the pot.
Peel the skin off the potatoes and add to a large mixing bowl. Using a hand mixer (or a masher), blend potatoes until mostly smooth. Next add butter, sugar, cream, vanilla, cinnamon and nutmeg and mix until well combined and potatoes are smooth.
Spoon mashed potatoes into dish and smooth with a spatula.

For the Crumble Topping

Whisk together flour, sugar, oats, cinnamon and nutmeg in a medium bowl. Melt butter in a microwave safe bowl. Add melted butter to dry ingredients and mix with a fork until well combined to create crumbs. Sprinkle the potatoes with the topping.
Add marshmallows to top of crumble topped potatoes. Create 6 rows of 4 regular sized marshmallows to cover the whole pan.
Bake for 20-25 minutes or until crumble is crisp and marshmallows are golden brown. You can also broil marshmallows a bit if you want them to have a more torched look.

Notes

Note 1: You can omit marshmallows if you would like.

Note 2: If you want a thicker consistency for potatoes, use just 1/2 cup heavy whipping cream.

Expert Tips

Broil the top. For a more torched look on the marshmallows, place the casserole under the broiler after cooking it in the oven.

Make ahead. Add the marshmallows and crumble topping right before baking!
