These classic cake donuts are fried at a lower temperature to produce their characteristic cracks and ridges.
- 4 cups (1 lb. 2 oz.) bread flour, sifted
- 1 cup sugar
- 4 tsp. baking powder
- 4 1⁄2 tsp. ground cinnamon
- 4 tsp. freshly grated nutmeg
- 3 tsp. ground ginger
- 2 tsp. ground allspice
- 1 1⁄2 tsp. kosher salt
- 1⁄2 tsp. ground cloves
- 2 eggs
- 1 1⁄4 cups sour cream
- 4 tbsp. unsalted butter, melted
- Canola oil, for forming and frying
- 2 cups confectioners' sugar
- 1 1⁄2 tsp. vanilla extract
Whisk flour, sugar, baking powder, 3 tsp. cinnamon, 3 tsp. nutmeg, ginger, 1½ tsp. allspice, salt, and cloves in a bowl; set aside. Combine eggs, sour cream, and butter in the bowl of a stand mixer fitted with a paddle attachment; beat until smooth. With the motor running, slowly add dry ingredients and mix until a soft, sticky dough forms.
Heat 2″ oil in a 6-qt. saucepan until a deep-fry thermometer reads 325°. Using lightly oiled hands, roll about ¼ cup batter into a loose, sticky ball; pat gently into a disk. With your thumb, make a 1½″ hole in the center of dough; carefully slide into oil and fry, flipping once, until puffed and golden, 4 to 5 minutes. Using a slotted spoon, transfer to a baking sheet with a wire rack; repeat with remaining dough and let donuts cool completely.
Whisk remaining cinnamon, nutmeg, and allspice, plus confectioners' sugar, vanilla, and ¼ cup water in a bowl until smooth. Dip tops of donuts in glaze and return to wire rack until glaze is set.
