Sweet Potato Doughnuts - cooking recipe

Ingredients

3 1/2 cups flour
1 cup sugar
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon ground cinnamon
1/2 teaspoon salt
2 large eggs, lightly beaten
1 cup sour cream
1 cup cooked mashed sweet potato (I roasted mine)
vegetable oil, for frying

Preparation

In a medium bowl, combine flour, sugar, baking powder, baking soda, cinnamon, and salt.
In a large bowl, combine eggs, sour cream, and sweet potato.
Gradually add flour mixture, stirring to combine.
Turn dough out onto a heavily floured surface.
Knead in flour with hands as needed (dough will be sticky).
Roll out dough to 1/2-inch thickness.
Cut out dough with a 2 1/4-inch round doughnut cutter.
No doughnut cutter? Use a soup can as a cutter then poke a hole in the middle of the dough round.
Using your fingers, stretch the dough until an inch opening is formed and the doughnut is about 3 \" wide.
Re-roll dough as needed.
In a Dutch oven, heat vegetable oil over medium heat to 360 degrees F.
Cook doughnuts, in batches of 4-5, in hot oil, 2 minutes per side, or until lightly browned.
Drain on paper towels.
