These cake-like baked sourdough apple cider donuts are buttery, moist, and spiced with reduced apple cider for rich fall flavor. Sourdough discard adds a subtle tang, and with no fermenting, waiting, or frying, they’re the perfect quick treat for cozy autumn mornings.
Reduce the Apple Cider. In a heavy-bottom saucepot, reduce the apple cider to 1/2 cup over medium heat. For me, this takes about 20-25 minutes. Retain any spices or solid bits (that's extra cider flavor!). Set aside to cool for at least 15 minutes.
240 g apple cider
Prep. Preheat the oven to 350° F and lightly grease a donut pan.
Mix the Dry Ingredients. While the cider cools, whisk together the flour, baking powder, salt, cinnamon, and nutmeg.
Cream the Butter and Sugar. In the bowl of a stand mixer, add the butter, brown sugar, and granulated sugar. Using a paddle attachment, cream the ingredients on medium speed for 30 seconds. Then, bump up the speed to medium-high and cream the butter-sugar mixture until it is light and fluffy, about 2-4 minutes.
140 unsalted butter, 165 dark brown sugar, 50 granulated sugar
Add the Remaining Wet Ingredients. Add the egg, sourdough discard, and vanilla. Mix on medium speed until fully combined, scraping the sides of the bowl as necessary.
1 large egg, 100 g sourdough discard, 1 teaspoon vanilla extract
Add the Flour Mixture. Add the flour mixture into the stand mixer bowl and mix on low speed until well combined. Do not overmix.
Pour in the Apple Cider. While the mixer is running on the lowest speed, slowly pour in the reduced apple cider. Mix until well-combined, but do not overmix. Scrape the sides of the bowl as needed.
Fill the Donut Pan. Fill the donut pan with the batter. I like to use a piping bag for this because it is easier and less messy. But you can also spoon it into the pan. I also like to use my finger or the back of a spoon to smooth the batter evenly in the pan.
Bake. Bake for 12-15 minutes or until a toothpick inserted in the thickest point of a donut comes out clean.
Melt the Butter. While the donuts bake, melt the butter for the topping either on the stovetop or in the microwave. Do not let it separate.
43 g unsalted butter
Make the Topping. Then, combine the sugar and cinnamon in a wide, shallow bowl or plate.
100 g granulated sugar, 1 teaspoon ground cinnamon
Cool the Donuts. When the donuts are out of the oven, transfer them to a wire rack to cool for a few minutes.
Add the Topping. When they are cool enough to handle, one at a time, brush the donut with the melted butter. Then generously dredge it on all sides through the cinnamon-sugar mixture.Repeat buttering and coating each donut. Then, repeat the baking process with the remaining batter.
