Servings: 10 servings
Ingredients
Sweet Potatoes
- 2 pounds sweet potatoes
- 2 tablespoons butter softened
- 1 tablespoon brown sugar
- 1 teaspoon cinnamon
- 1 pinch coarse kosher salt
Streusel Topping
- 5 tablespoons butter softened
- 4 tablespoons brown sugar
- 5 tablespoon flour
- ½ teaspoon cinnamon
- 2 cups marshmallows
Instructions
- Preheat oven to 400°F.
- Combine 1/2 tsp cinnamon, 5 tbsp butter, 4 tbsp brown sugar, and flour. Combine until it becomes a sticky, sand like consistency. Set aside.
- Make your mashed sweet potatoes. You can do this in the Instant Pot, or you can peel and boil them on the stove.
- Once boiled and soft, drain them and add them back to the pot with 1 tbsp brown sugar and the remaining butter and cinnamon. Mash until smooth.
- Spread your mashed sweet potatoes smoothly and evenly into a large casserole dish.
- Sprinkle half of the marshmallows across the top (there will be gaps at this point).
- Sprinkle half of the streusel topping across the top.
- Top with remaining marshmallows and streusel.
- Bake in the oven at 400°F for 6 minutes. WATCH CLOSELY. You do not want the marshmallows to burn.
- Remove from the oven and serve hot.
