The Best Apples for Baking
When baking with apples, you want to choose a variety that holds up well, without becoming too mushy.
We recommend using Golden Delicious, Granny Smith, Braeburn, or Honey Crisp because their firm flesh is ideal for baking. The tartness of Granny Smith apples helps balance out the sweetness of the sourdough cake as well.
Ingredient Notes and Substitutions
- Active sourdough starter: fed 12-24 hours before starting the recipe
When we say active, we mean a mature starter that is at least a week old and always doubles in size within 4-6 hours of feeding. It doesn’t mean you need to use it at the peak activity after a feeding. - Butter: using room temperature or softened butter is essential in this frosted sourdough cake recipe! If you are in a hurry, cut the butter into cubes so it softens faster. Or put it in a glass bowl over a bowl of warm water.
- Vegetable oil: although you could use all butter or all vegetable oil, the combination of butter and oil gives you that buttery goodness flavor, while vegetable oil keeps it light but moist.
- Granulated sugar and brown sugar: the mixture of granulated sugar and brown sugar gives the batter a creaminess from the white sugar, while the brown sugar adds a depth of flavor, thanks to the molasses in it.
- Eggs: room temperature eggs are a must! Want to bake without eggs? Discover this effective egg replacement for cake.
- Self-rising flour: this isn’t the same as all-purpose flour! Self-rising flour combines baking powder, all-purpose flour, and a little salt. See our post on best self rising flour to save money by making it yourself.
- Baking soda: be sure to use baking soda and not baking powder! They are not the same.
- Apples: you can use any variety of apples here. Although we’ve shared our favorites above, feel free to use your favorite.
Recipe Variations
- Swap the frosting: Instead of maple cream cheese, try a simple vanilla glaze or a dusting of powdered sugar for a lighter topping. You can also add chopped walnuts or pecans on top for a little crunch. For chocolate goodness, add cocoa powder or Dutch chocolate.
- Use pears instead of apples: Pears bring a mellow sweetness and work just as well in this recipe. Choose ripe but firm pears and dice them small before folding them into the batter.
- Make it into muffins: Scoop the batter into a lined muffin tin and bake at 350°F for 18–22 minutes. This is a great option for breakfast or lunchbox treats.
- Add raisins or dried cranberries: Fold in ½ cup of raisins or cranberries for extra bursts of sweetness. This variation pairs nicely with the spice blend and sourdough flavor.
Equipment Used in this Recipe

🎯 TFN Pro Tip
To warm cold eggs quickly, place them in a bowl of warm water for about 10 minutes.
How to Make Sourdough Discard Cake
- Don’t overmix the batter ingredients.
Use a stand or hand mixer to beat the butter, oil, sugar, and eggs in a large just until the batter is light in color and creamy.
- Stir the dry ingredients together first.
In a large bowl, stir all the dry ingredients together before adding them to the batter. This helps prevent over-mixing the batter, so you’ll have a lighter texture sourdough cake.
- Let the cake completely cool before frosting.
To prevent the cream cheese frosting from melting, let it cool for at least 30 minutes before frosting the sourdough cake.
If you aren’t a fan of cream cheese frosting, consider topping your sourdough discard apple cake with a batch of fluffy Swiss meringue buttercream instead.
The scent of this amazing combination will have you itching to cut that first slice before the sourdough apple cake is even frosted!
Serving Suggestions
This sourdough discard cake is best served at room temperature, allowing the flavors to shine and the frosting to soften slightly. It makes a cozy dessert on its own, but it’s also lovely paired with a hot cup of coffee or tea. For a fall-inspired touch, sprinkle a bit of cinnamon over the frosted top or add a few thin apple slices as a garnish. If you’re serving a crowd, cut the cake into small squares for easy sharing. And for something extra indulgent, a scoop of vanilla ice cream on the side brings a creamy contrast to the spiced crumb.

This is the best dessert ever! I made it for a holiday party and won the Top Chef award. I did make a few edits :- I added three extra apples, vanilla to the frosting a the cake. I also bake it for 5 minutes less. Absolutely amazing. Thank you.
