Baking spray with flour, such as Baker’s Joy
2 cups all-purpose flour
1 1/2 cups sugar
2 teaspoons baking powder
1 teaspoon ground cinnamon
1/2 teaspoon ground nutmeg
1/2 teaspoon kosher salt
1 extra-large egg, lightly beaten
1 1/4 cups whole milk
2 tablespoons unsalted butter, melted
2 teaspoons pure vanilla extract.
Preheat the oven to 350 degrees. Spray 2 donut pans well.
Into a large bowl, sift together the flour, sugar, baking powder, cinnamon, nutmeg, and salt. In a small bowl, whisk together the egg, milk, melted butter, and vanilla. Stir the wet mixture into the dry ingredients until just combined.
Spoon the batter into the baking pans, filling each one a little more than three-quarters full. Bake for 17 minutes, until a toothpick comes out clean. Allow to cool for 5 minutes, then tap the donuts out onto a sheet pan.
For Topping you can use melted chocolate and sprinklers.
