Sourdough Peach Cobbler

There's something about our Southern Sourdough Peach Cobbler that feels like warm porch lights and summer canning jars all at once, sweet peaches bubbling up under a golden, tangy crust that is straight from our Grandmother's cookbook.

Using sourdough starter gives the cobbler that cozy, slightly tangy flavor (in a “wait… what makes this so good?” way) while still keeping it totally doable for beginner and intermediate bakers. So, grab your fresh or frozen peaches and let's make a cobbler that deserves the loudest “mm-hmm” at dessert time.

At Avdaye, we add lots of tips in all of our recipes – because we are a home cook without any formal training, and we find we are more confident making dishes when we understand why it works, and what each ingredient means to the flavor of a recipe. Our goal is for even the most beginner home cook to feel empowered in the kitchen.

How to Make Sourdough Discard Peach Cobbler

This sourdough discard peach cobbler starts the Southern way – our great-grandmother's way – by melting butter in a hot cast iron skillet until it sizzles. The tangy, tender batter made with sourdough discard (our modern addition) is poured right over the bubbling butter, creating crispy edges and a soft center.

Sourdough Discard Peach 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.
• Peaches (3) – Fresh, sliced peaches provide juicy, 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.

Steps to Make Sourdough Discard Peach Cobbler

Once you've gathered your ingredients, we will use the following method:

Prep Ingredients

Slice your peaches and preheat the oven to 350 degrees.

Melt Butter

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.

Mix Batter

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

Pour, Sprinkle, Bake

Pour the batter over the melted butter, do not stir! Add the peaches directly on top of the batter and bake for 40 minutes or until browned on top and a toothpick comes out clean. Enjoy with ice cream or whipped cream!

Kitchen notes

Use ripe but firm peaches. They hold their shape better during baking and offer the best flavor.

Peel the peaches for smoother texture. Blanch them briefly in boiling water to make peeling easier.

Macerate the peaches. Toss with a bit of sugar and let sit for 10 -15 minutes to draw out juices and intensify flavor.

Use active or discard sourdough. Discard adds tang, while active starter can provide more rise and chew.

Don't overmix the batter. Stir until combined to keep the topping tender.

Preheat the oven fully. This ensures a good rise and golden color.

Place a baking sheet underneath. Catch any bubbling fruit juices that might overflow.

Let it rest after baking. Cool for 15-20 minutes to allow the cobbler to set and the flavors to meld.

Serve with ice cream or whipped cream. The creamy contrast enhances the warm, tangy-sweet dessert.

Sourdough Peach Cobbler FAQs

Can we use canned or frozen peaches instead of fresh?

Yes, drain canned peaches well or thaw and pat dry frozen ones to avoid excess moisture.

Do we need to peel the peaches?

Peeling is optional, but it creates a smoother texture; leave the skins on for a more rustic feel.

What if we don't have sourdough discard?

You can substitute with plain yogurt or buttermilk in equal amounts for a similar tang.
