7 Secrets to the Ultimate Overnight Sourdough Apple Cake

The magic starts with sourdough’s natural fermentation. Enzymes break down starches overnight, creating that tender crumb we crave. It’s not hype it’s science making your Overnight Sourdough Apple Cake irresistible.
Fresh apples provide juiciness without sogginess when diced just right. The crumble topping? Pure genius for crunch contrast. For deeper insight into sourdough’s fermentation powers, check out this detailed explanation on sourdough microbiology.
Pro tip: Use a springform pan for easy release and perfect height. This cake rises beautifully, especially after its chilly overnight rest. Humorously, I once baked it straight away good, but the overnight version? Chef’s kiss.
Ingredients
- 115 g (8 tbsp) unsalted butter, softened
- 150 g (3/4 cup) light brown sugar
- 2 large eggs, room temperature
- 100 g (about 1/2 cup) sourdough starter (active or discard)
- 190 g (1 1/2 cups) all-purpose flour
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1 tsp ground cinnamon
- 1/4 tsp fine sea salt
- 1/4 cup milk
- 300 g (about 2-3 medium) peeled and chopped apples, 1/2-inch dice
For the crumble topping:
- 75 g all-purpose flour
- 50 g granulated sugar
- 50 g unsalted butter, softened
- 1/4 tsp fine sea salt
Instructions
- Preheat oven to 350°F (175°C). Butter an 8-inch springform pan; set aside. Make crumble: Mix flour, sugar, salt in a bowl. Rub in butter with fingertips until crumbly. Chill while prepping batter.
- Peel and chop apples into 1/2-inch dice. Set aside. In a stand mixer or bowl, cream butter and brown sugar until fluffy, about 3 minutes.
- Add eggs one at a time, beating well after each. Mix in sourdough starter until smooth. Combine dry ingredients (flour, baking powder, soda, cinnamon, salt) and add alternately with milk.
- Fold in apples gently the batter will be thick. Scrape into pan, smooth top, and scatter crumbles evenly.
- For immediate bake: Oven center rack, 55-60 minutes until toothpick clean. For Overnight Sourdough Apple Cake magic: Cover and fridge up to 12 hours. Bake cold next day, same time/temp.
- Cool 1+ hour in pan. Release springform, slice, and serve warm. Dust with powdered sugar if desired.

Pro Tips for Storing Your Baked Goods
Store Overnight Sourdough Apple Cake covered at room temp up to 2 days. For longer, fridge in airtight container up to 5 days. Reheat slices at 300°F for 10 minutes to revive that fresh-baked vibe.
Freezing works wonders: Wrap tightly, up to 3 months. Thaw overnight in fridge. FYI, crumbles stay crisp if you freeze unbaked and bake fresh.
