Creating the delicious Sweet Potato Marshmallow Mousse is straightforward when you follow these steps:

1. Boil Sweet Potatoes: Place sweet potatoes in a large pot of boiling water. Cook until soft, about 15-20 minutes. Drain and let cool.
2. Mash Sweet Potatoes: Once cooled, peel and mash the sweet potatoes in a large bowl until smooth.
3. Mix Marshmallows: Add mini marshmallows to the mashed sweet potatoes and mix until well combined.
4. Whip Cream: In a separate bowl, whip heavy cream until soft peaks form. Gradually add powdered sugar, vanilla extract, cinnamon, and salt. Continue whipping until combined.
5. Fold Mixtures: Gently fold the whipped cream mixture into the sweet potato-marshmallow blend until fully incorporated. Be gentle to maintain a light and fluffy texture.
6. Chill: Spoon the mousse into serving bowls or glasses. Refrigerate for at least 30 minutes to allow the flavors to meld and the mousse to set.
7. Serve: Once chilled, you can garnish with whipped cream and extra marshmallows if desired.

These simple steps will guide you toward creating an incredible Sweet Potato Marshmallow Mousse that will leave your guests impressed!
