This delightful recipe combines the tangy flavor of sourdough discard with the sweet and comforting taste of applesauce in a moist and tender cake. It's the perfect way to use up your excess sourdough discard while creating a delicious treat for any occasion.
Preheat oven to 170C (338F). Grease a cake pan with butter and set aside. I've used a square pan 10" x 10" or 22.5cm x 22.5cm.
In a large mixing bowl add all of the dry ingredients - all purpose flour, brown sugar, baking powder, baking soda, salt, cinnamon, nutmeg and ginger. Mix together until well combined.
In the centre of the dry ingredients, create a well and add all of the wet ingredients to it - sourdough starter, egg, olive oil, Greek yogurt, applesauce and vanilla.
Stir the wet ingredients together in the well and then combine with the dry ingredients to form a batter.
Pour the cake batter into the greased cake pan.
Bake for 40 minutes at 170C (338F). You can check the cake is done by inserting a skewer in the centre. If it comes out clean, you can remove it from the oven. It's ok if it needs a few more minutes to cook through.
Allow the cake to cool in the pan.
Frost with vanilla yogurt glaze or dust with powdered sugar to serve.
Vanilla Yogurt Glaze
Combine Greek yogurt, vanilla extract and powdered sugar. Whisk together until glossy. Pour over the cooled cake.
Notes
Sourdough Starter - you can use sourdough discard or active sourdough starter for this recipe. The only caveat here is, don't use sourdough discard that's too old and sour (should be no more than one week old). If it's too sour, it will overpower the flavor of the applesauce cake.Greek Yogurt - if you don't want to use Greek Yogurt, you can use any unsweetened plain yogurt or you can use buttermilk or plain milk as a straight swap. Applesauce - I've used store bought applesauce, but you can use homemade applesauce if you prefer. Spices - you can use less spices if you prefer, but the spices listed in the recipe do not overpower the cake. You can use pumpkin pie spice or apple pie spice if you like too.
