What Is Sourdough Starter?
A sourdough starter is a fermented mixture of flour and water used to naturally leaven baked goods. An active starter is bubbly, doubled in size, and recently fed, usually within the last 4–12 hours. For this cobbler, we use active starter for the best rise and subtle tang.
No active starter? You can substitute with equal parts flour and milk or flour and water to get the right consistency.
Can I Use Sourdough Discard Instead?
You can, but you’ll need to add baking powder for rise, since discard isn’t active. This recipe includes 2 teaspoons of baking powder so it works either way!

Why Use Sourdough Starter in Cobbler?
Sourdough starter doesn’t just leaven bread, it adds flavor and tenderness to baked goods like cobbler. The natural acidity in the starter helps break down gluten, creating a soft, moist texture.
Plus, the tangy notes from the fermented dough perfectly balance the sweet blackberries. It’s a subtle but delicious difference you’ll taste in every bite.
If you’ve never baked with sourdough outside of bread, this cobbler is the perfect place to start.
How to Pick the Best Blackberries
Whether you’re foraging wild berries or buying them at a market, here are a few tips:
- Look for plump, dark purple-black berries with no red or green tones.
- Ripe blackberries should be slightly soft, not firm or mushy.
- If using frozen blackberries, thaw them first and drain off excess juice.
Pro Tip: If your berries are a little tart, you can toss them with a tablespoon of sugar before adding to the dish.

How to Make Sourdough Blackberry Cobbler
1. Preheat oven to 375°F.
Wash and dry your berries if needed. Lightly grease or line your 9×13 dish. Spread berries evenly in the bottom.

FAQs
Can I cut this recipe in half?
Yes! Halve all ingredients and bake in an 8×8 dish. Check for doneness around 45–50 minutes.
Why is my cobbler runny?
It likely needs more time to bake. The filling should be bubbly, and the topping golden and firm, not liquidy.
How do I know when it’s done?
The top will be lightly browned, and the edges bubbly. A toothpick inserted should come out clean.
Does blackberry cobbler need to be refrigerated?
Yes. Keep leftovers refrigerated to maintain freshness and food safety.
Recipe Tips & Variations
- Use peaches, cherries, or blueberries if blackberries aren’t in season.
- Add a teaspoon of vanilla extract or cinnamon to the batter.
- Want a gluten-free version? Use a gluten-free sourdough starter and flour blend.
- Make individual cobblers in ramekins for easy serving and freezing.
Can I Make This Cobbler with Other Fruit?
Yes! This sourdough cobbler base is incredibly versatile. You can swap the blackberries for:
- Blueberries
- Raspberries
- Peaches
- Cherries
Or go wild and mix two together, like blackberry peach cobbler or cherry blackberry. The batter stays the same; just adjust the sweetness slightly if your fruit is especially tart or sweet.
