A recipe for sourdough apple cake: a moist and delicious cake made with shredded apples and your sourdough starter.
Jump to:
Fall means apples, and baking, and spices, and cozy afternoons in the kitchen. And this recipe is the embodiment of all of these things. On top of that it’s absolutely delicious, and a great way to use up that discard sourdough starter.
The cake is moist and tender with just the right amount of fall spices, plenty of fresh apple, and not too sweet. The frosting is somewhere between a buttercream and a true cream cheese frosting, with hint of apple spice flavor.
You’ll love it.

About the boiled cider
If you have ever baked with boiled apple cider, you know what an amazing apple-spice flavor it lends to everything. But if you have don’t have it on hand, that’s okay. You can still make this cake.
A few options, in case you don’t have any:
- Make your own boiled cider by simply reducing apple cider in a pot on the stove until it reduces by 1/8. (You can find full instructions here. It’s easy but takes a long, long time.)
- Substitute with half apple sauce and half molasses (adding to the molasses already in the recipe).
- For the cream cheese frosting, simply leave it out. No big deal.
However, it’s a truly delicious and versatile ingredient for all your fall baking and I encourage you to make some or buy some to have on hand up until Christmas.
How to grate apples
Of course you could do it by hand with a big box grater. Or if that just feels like too much, use the shredding disc of your food processor. Cut the apples into chunks and it will do the work for you in a matter of seconds. Yes, they will technically be shredded, not grated. That’s okay.
Baking cakes with sourdough starter
If you have never baked something sweet before with your sourdough starter, don’t worry. There will be no sour taste. There is a (very) slight tanginess, similar to baking with sour cream or Greek yogurt.
The real benefit of a cake made with sourdough starter is that it’s a great use of your sourdough discard. This recipe calls for sourdough starter in its unfed state. So as you are discarding, save what you pour off to bake this delicious apple cake!

Let’s bake the cake, step by step
This is an easy recipe, and as long as you have an electric mixer of some sort, it won’t take you long to make. Start by creaming the butter, sugar, oil, and eggs together in a large mixing bowl. This will take a a few minutes, at least three minutes of beating on medium speed. Add the molasses and the boiled cider and mix.
Then, in a separate large mixing bowl, combine all the dry ingredients: the flour, spices, salt, baking soda, and baking powder. Add them to the butter/ sugar/ oil/ egg mixture and blend on low until just combined.
Finally, add the discarded sourdough starter and the grated apple and mix until everything is throughly combined.
Pour the batter into the prepared pan and bake. The cake is done when a toothpick comes out clean and the edges are slightly browned.
Allow the apple cake to cool, right in the pan, for a few hours. You want it completely cool before you frost it.
Cut into squares and serve directly out of the pan. Easy!
If you have leftovers, keep them in the fridge so the frosting stays fresh. It keeps very well for a few days if kept tightly wrapped.

Delicious cake and frosting. Had a half gallon of cider and couldn’t find boiled cider so I made my own per your link. Thank you!
