Cinnamon Apple Sourdough Cake

This Cinnamon Apple Sourdough Cake is the perfect balance of cozy fall flavors and tangy sourdough depth. With warm cinnamon-spiced apples folded into a tender, moist cake, it's a great way to use up sourdough discard while making something irresistibly delicious. Serve it as is, or take it to the next level with a scoop of vanilla ice cream or a drizzle of icing!

Equipment

  • 1 9x9 baking dish

Ingredients
 

Apples

  • 2 large apples cut into ½” pieces (we use Fuji but use your favorite variety!)
  • ¼ teaspoon fine sea salt
  • 1 teaspoon cinnamon
  • ¼ teaspoon ground nutmeg optional
  • ⅓ cup all-purpose flour

Cake

  • 180 grams or 1 ½ cups all-purpose flour
  • 10 grams or 1 tablespoon cornstarch
  • 4 grams or ½ teaspoon baking soda
  • 6 grams or 1 teaspoon baking powder
  • 4 grams or ½ teaspoon salt
  • 2 teaspoons cinnamon
  • ½ teaspoon ground nutmeg optional
  • 6 tablespoons unsalted butter softened
  • 200 grams or 1 cup granulated sugar plus additional for topping
  • 2 eggs at room temperature
  • 90 grams or ½ cup whole milk
  • 170 grams or ¾ cup sourdough discard
  • 1 teaspoon vanilla extract

Instructions

  • Preheat the over to 350°F and prepare a 9x9 in baking dish by lining it with parchment paper and spraying the paper with cooking spray.
  • In a mixing bowl, whisk together the dry ingredients.
    180 grams or 1 ½ cups all-purpose flour, 10 grams or 1 tablespoon cornstarch, 4 grams or ½ teaspoon baking soda, 6 grams or 1 teaspoon baking powder, 4 grams or ½ teaspoon salt, 2 teaspoons cinnamon, ½ teaspoon ground nutmeg
  • In the bowl of a stand mixer use the paddle attachment on medium-low speed to cream the butter and sugar until light and fluffy, about 5 minutes. Add the eggs one at a time, completely incorporating the first egg before adding the next.
    6 tablespoons unsalted butter, 200 grams or 1 cup granulated sugar, 2 eggs
  • Add in the milk, sourdough starter, and vanilla extract and mix until everything is incorporated together.
    90 grams or ½ cup whole milk, 170 grams or ¾ cup sourdough discard, 1 teaspoon vanilla extract
  • With the mixer on low, start adding the flour mixture a large spoonful at a time until you’ve added all the flour. Don’t worry if all the flour is not mixed in yet.
  • In the bowl you had your flour mixture in, toss the apple pieces with ⅓ cup of all-purpose flour, salt, cinnamon, and nutmeg until they are all well coated. Add the apples to your mixing bowl and gently fold them in along with any remaining dry flour in the mixture.
    2 large apples, ¼ teaspoon fine sea salt, 1 teaspoon cinnamon, ¼ teaspoon ground nutmeg, ⅓ cup all-purpose flour
  • Once everything is well incorporated, pour the batter into the prepared baking dish and sprinkle about 2 tablespoons of granulated sugar over the top of the batter.
  • Bake at 350°F for 45-50 minutes. You want the top to be golden brown and a toothpick or cake tester to come out cleanly after inserted in the center.
  • Cool completely, optionally top with your favorite icing, serve (with vanilla ice cream like we do), and enjoy!
