Creamy Sweet Potato Casserole (ABSOLUTE DELISH)

Boil the sweet potatoes: Place the peeled and cubed sweet potatoes in a large pot, cover with water, and bring to a boil. Cook for about 10-12 minutes until tender and easily pierced with a fork.
Drain the sweet potatoes and return them to the pot.
Step 2: Make the Sweet Potato Base
Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
Mash the boiled sweet potatoes until smooth.
Add the melted butter, brown sugar, granulated sugar, heavy cream, eggs, vanilla extract, and cinnamon. Mix until all ingredients are well incorporated and the mixture is smooth.
