I make mine similar to this , I don't know exact measurements, nor do I often use them
I usually use more vanilla & spices.
3 medium sweet potatoes (about 1 1/2 pounds)
4 tablespoons unsalted butter
2 large eggs
1/2 cup heavy cream
1/2 cup light brown sugar
1/4 cup regular sugar
1 tablespoon pure vanilla extract
1/2 teaspoon ground cinnamon
1/2 teaspoon fine salt
1/4 teaspoon freshly grated nutmeg
Pinch ground cloves
I combine all dry then add to wet mix until smooth and name for about 45 mins to an hour at 350.
