Apple-Cider Doughnut Cake

Step 1

Preheat oven to 350 degrees. Butter and flour a 12-cup Bundt pan. In a large bowl, whisk together both flours, baking powder, 1 teaspoon cinnamon, baking soda, and salt. In another bowl, whisk together 1 1/2 cups sugar, cider, oil, applesauce, vanilla, and eggs. Add egg mixture to flour mixture; whisk until combined. Transfer batter to prepared pan.

Step 2

Bake, rotating pan halfway through, until a tester inserted in center comes out clean, 45 to 50 minutes. Transfer pan to a wire rack set over a rimmed baking sheet; let cool 15 minutes. Meanwhile, mix together remaining 1/4 cup sugar and 1/2 teaspoon cinnamon.

Step 3

Invert warm cake onto rack. Brush with melted butter, then sprinkle liberally with cinnamon sugar. Let cool completely before serving. Cake can be stored, covered, at room temperature up to 2 days.
