‘Grandma’s Sweet Surprise’ is what we nicknamed it. Everyone’s favorite, and you’d never guess it only takes five ingredients! (Page 2 ) | March 16, 2025

1 teaspoon vanilla extract
1 cup mini marshmallows
Directions
Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine the mashed sweet potatoes, brown sugar, melted butter, and vanilla extract. Mix until smooth and well combined.
Transfer the sweet potato mixture into a greased baking dish, spreading it evenly.
Sprinkle the mini marshmallows evenly over the top of the sweet potato mixture.
Bake in the preheated oven for 25-30 minutes, or until the marshmallows are golden brown and the casserole is heated through.
Allow to cool slightly before serving.
Variations & Tips
For a nutty twist, sprinkle chopped pecans over the marshmallows before baking. You can also add a pinch of cinnamon or nutmeg to the sweet potato mixture for a warm, spiced flavor. If you prefer a less sweet version, reduce the brown sugar to 1/4 cup. For a dairy-free option, substitute the butter with coconut oil or a plant-based alternative.
