At Sweet C’s, I add lots of tips in all of my recipes – because I am a home cook without any formal training, and I find I am more confident making dishes when I understand why it works, and what each ingredient means to the flavor of a recipe. My goal is for even the most beginner home cook to feel empowered in the kitchen.

How to Make Blueberry Cobbler from sourdough discard

Discard Blueberry Cobbler Ingredients

First assemble the following ingredients:

  • Butter (1/2 cup) – Melted butter forms the rich, buttery base that helps create a golden, crisp edge on the cobbler.
  • Sugar (1 cup) – White sugar sweetens the batter and balances the tartness of the sourdough.
  • All-purpose flour (1 cup) – Flour provides structure to the cobbler topping, yielding a soft and cakey texture.
  • Baking powder (2 teaspoons) – Baking powder helps the cobbler rise and become light and fluffy.
  • Salt (1/4 teaspoon) – A pinch of salt enhances the flavor and balances the sweetness.
  • Milk (3/4 cup) – Milk adds moisture and helps create a pourable batter.
  • Sourdough discard (1/3 cup) – The discard adds a subtle tang and helps tenderize the cobbler.
  • Vanilla extract (1 teaspoon) – Vanilla brings warmth and depth to the flavor of the batter.
  • Blueberries (2 cups) – Fresh blueberries provide the sweet fruit that shines as the cobbler’s centerpiece.
  • Brown sugar (1/4 cup) – Brown sugar adds caramel-like sweetness and richness to the fruit layer.

Discard Blueberry Cobbler Process

Once you’ve gathered your ingredients, we will use the following process:

A stick of butter sits in a black cast iron skillet, ready to craft sourdough blueberry cobbler, surrounded by bowls of blueberries, sugar, brown sugar, vanilla, and a jar of milk on a red-handled towel.

Prep

Rinse and dry your blueberries, if you are using frozen blueberries be sure to defrost them.

Place the butter in a 12-inch cast iron skillet and place it in the oven until the butter melts. Remove from the oven and set aside.

A glass bowl containing flour, sugar, and baking powder sits on a counter near a container of blueberries and a dish of brown sugar—ingredients ready for a homemade sourdough blueberry cobbler.

Mix Batter

Combine all the dry ingredients then add the milk, vanilla, and sourdough discard, mix until just combined.

A cast iron skillet filled with unbaked sourdough blueberry cobbler—batter, melted butter, blueberries, and brown sugar—rests on a white countertop with a towel and a container of blueberries nearby.

Add to Pan With Blueberries

Pour the batter over the melted butter, do not stir! Add the blueberries directly on top of the batter.

Bake

Bake for 40 minutes or until browned on top and a toothpick comes out clean.

Tips and Tricks to Perfect Cobbler with Blueberries

Use fresh or frozen blueberries – Fresh berries offer the best texture, but frozen can be used without thawing to prevent excess juice.

Add lemon zest or juice – Tossing the blueberries in a splash of lemon brightens the flavor and complements the blueberries.

Do not stir the batter into the fruit – Pour it on top and let it naturally bake into layers for the best texture.

Add a pinch of cinnamon or nutmeg – Tossing the blueberries in these spices adds depth to the fruit.

Let the cobbler cool before serving – This allows the filling to set and flavors to meld.

Serve with a scoop of vanilla ice cream or whipped cream – It adds creamy contrast to the warm, tangy-sweet dessert.

FAQs

Can I use frozen blueberries instead of fresh?

Yes, but do not thaw them first—use straight from the freezer to prevent the filling from becoming too watery.

What does sourdough discard do in the cobbler?

It adds a mild tang and helps create a tender, flavorful batter with a slight chew.

Can I substitute the sourdough discard with something else?

Yes, use plain yogurt, buttermilk, or even milk with a splash of vinegar in equal amounts.

How do I know when the cobbler is done?

It’s ready when the top is golden brown and a toothpick inserted into the center comes out clean.

How should I store leftovers?

Cover and refrigerate for up to 3 days; reheat in the oven or microwave before serving.

Can I freeze the cobbler?

Yes, freeze the fully baked cobbler for up to 2 months; thaw overnight in the fridge and reheat before serving.

Notes

You can use a different size cast iron skillet if you want but the fruit may end up very close together which will increase baking time a bit.
