Step 1

Preheat the oven to 350°F. Grease an 8”x10” casserole dish (8×8 or 9×9 works too).

Step 2

Fill a large pot with sweet potato pieces and enough water to cover by 2 inches. Bring to a boil over high heat and cook until fork tender, about 10 minutes.

Step 3

Drain water from potatoes and return potatoes to the pot. Using a potato masher or electric mixer, mash until mostly smooth. Add remaining ingredients (except topping ingredients and mix until combined.

Spoon sweet potatoes into the casserole dish and use the back of a wooden spoon or mixing spatula to smooth out. Sprinkle marshmallows over top of mashed sweet potatoes.

Step 5

Add butter to a medium sized microwave safe bowl. Microwave on full power to melt the butter. Add remaining topping ingredients to the bowl, and use a fork to combine. Sprinkle over the top of casserole.

Step 6

Place the casserole in the preheated oven and bake for 20-25 minutes, or until the streusel is crisp and marshmallows are golden brown.
