A Great Way To Use Your Summer Berry Harvest 

One of my very favorite things to do outside during the summer is pick berries with my little one. We have a few blackberry bushes as well as a few blueberry bushes, so we are never short on berries. Honestly, I have to figure out what to do with all of our blackberries since our bushes produce so many! Outside of eating the berries by themselves or making jams, I thought I would try to get creative with how I incorporate them in my baking. Peach cobbler is such a delicious summertime treat. I thought it couldn’t hurt to add some blackberries and see what happens! Turns out, it makes peach cobbler even better- at least in my family’s opinion! Even my husband, who isn’t big on sweets, loves this dessert!

Does Sourdough Really Go In Dessert Recipes?!

When you first hear of putting sourdough into a dessert recipe, you may be a little put off at the thought. Sourdough bread is fermented, and it tastes like it as well. It has a naturally tangy, hearty flavor that is deliciously unmistakeable. You may be wondering if this flavor profile really has a place in baking desserts. I’m here to tell you that not only does sourdough taste amazing in sweets, it also gives your baked goods a few health benefits that you can feel good about. Breads and baked goods can be hard on the digestive system and full of gluten. Sourdough contains a natural yeast that helps your gut digest baked goods a little easier. It is also naturally lower in gluten content. Baking sweets that are easier on the digestive system seems like a no brainer to me. 

As far as that sourdough tang goes, the tangy taste is not as noticeable or as savory as you would think it is.  It blends wonderfully with sweet recipes! If you’re a sourdough enthusiast like me, you know the fermentation process of an active sourdough starter or even unfed sourdough starter adds a depth of flavor that takes baked goods to the next level. Using sourdough discard in this sourdough berry cobbler imparts a subtle tang that pairs beautifully with the sweetness of fresh peaches and fresh blackberries. This easy recipe is perfect for beginners and seasoned bakers alike. Whether you’re new to sourdough recipes or a pro with your active starter, this sourdough cobbler recipe is a delicious way to use up that sourdough starter discard.

Ingredients for Sourdough Blackberry Peach Cobbler

This easy peach cobbler relies on simple ingredients you likely already have in your pantry. Here’s what you’ll need for the filling and cobbler dough:

For the Fruit Filling:

•  4 fresh peaches, peeled and sliced (or canned peaches, drained, in a pinch)

•  2 cups fresh blackberries (or fresh blueberries for a twist)

•  ½ cup white sugar (or monk fruit)

•  1 tablespoon lemon juice

-1 tsp cinnamon

•  1 teaspoon lemon zest (for a bright, zesty kick)

•  1 tablespoon cornstarch (to thicken the pour berry mixture, but not entirely necessary)

For the Sourdough Cobbler Topping:

•  1 1/4 cups all-purpose flour (or whole wheat flour for a heartier texture)

•  1/4 cup sourdough discard (from an unfed sourdough starter)

• 1 cup white sugar (or monk fruit)

•  2 teaspoons baking powder (the leavening agent)

•  ½ teaspoon salt

• 1 cup milk 

•  ½ cup (1 whole stick of butter), melted

•  2 tablespoons coarse sugar (for sprinkling on top of the cobbler)

Optional:

•  Scoop of ice cream or sour cream for serving

Step-by-Step Instructions for Sourdough Blackberry Peach Cobbler

This sourdough blackberry cobbler recipe is as simple as it is delicious. Let’s break it down:

Step 1: Prepare the Fruit Filling

1.  Preheat your oven to 350°F (190°C) and place a rack in the center. Grease a large cast iron skillet or a 9×13-inch baking dish with melted butter.

2.  In a large mixing bowl, combine the fresh peaches, fresh blackberries, white sugar, lemon juice, lemon zest, cinnamon, and cornstarch. Toss gently to coat the fresh fruit evenly and prevent excess water from forming.Set aside while you prepare the cobbler topping.

Step 2: Make the Sourdough Cobbler Dough

1.  In a small mixing bowl, whisk together the all-purpose flour, baking powder, and salt—these are your dry ingredients.

2.  In another small bowl, combine the sourdough discard, milk, and melted butter. Stir until smooth. This is your wet ingredients mixture.

3.  Pour the wet ingredients into the dry ingredients and stir until just combined. The cobbler dough should be thick but spreadable, similar to a biscuit dough or cookie dough.

4.  If you want a more fermented dough, you can cover the dough and let it sit at room temperature for a few hours or even overnight for extra depth of flavor. But for a quick easy recipe, you can use it right away!

Step 3: Assemble and Bake

1.  Pour the fruit filling into your prepared dish or skillet. Spoon the cobbler dough over the fruit filling in dollops, leaving some gaps for the fruit to peek through. This rustic look is part of the charm!

2.  Sprinkle the coarse sugar over the top of the cobbler for a crunchy, golden brown finish.

3.  Place the baking dish or cast iron pan on a baking sheet lined with aluminum foil to catch any drips. Bake in the preheated oven for 35–45 minutes, or until the cobbler bakes to a golden brown and the fruit is bubbling.

4.  Check doneness by ensuring the biscuit topping is cooked through and the fruit is tender. If the top browns too quickly, cover loosely with aluminum foil.

Step 4: Serve and Enjoy

Let the cobbler cool for 10–15 minutes before serving—it’s best enjoyed warm with a scoop of vanilla ice cream! Store leftovers in an airtight container in the fridge and reheat the next day for another delicious way to enjoy this treat. We even had it for breakfast one morning with a cup of coffee-yum!

Tips for the Best Sourdough Cobbler

•  Fresh vs. Canned Peaches: While fresh peaches are ideal during peach season, canned peaches work in a pinch. Just drain them well to avoid excess water in the filling.

•  Sourdough Discard: This recipe is perfect for using up sourdough starter discard. If you’re using an active sourdough starter, it’ll work just as well!

•  Mix Up the Berries: Swap fresh blackberries for fresh blueberries or raspberries for a different twist on this sourdough berry cobbler.

•  Make It Ahead: Prepare the fruit filling and cobbler dough separately, then assemble and bake when ready. The dough can sit in the fridge overnight for a more fermented dough flavor.

Why This Recipe Is A Family Favorite

This sourdough peach cobbler recipe is one of my favorite recipes because it’s so versatile and forgiving. The sourdough discard adds a unique tang that balances the sweetness of the sugar mixture and the juiciness of the fresh fruit. The biscuit topping, made with simple ingredients like all-purpose flour, baking powder, and melted butter, comes together quickly and bakes into a perfectly golden brown crust. Plus, it’s a fantastic way to bring people together around the table this summer. Whether you’re hosting a summer barbecue or just craving a sweet treat, this twist on an easy peach cobbler delivers every time. It’s a cozy, delicious summertime dessert that can be enjoyed well into the fall.

Serving Suggestions and Storage

This sourdough blackberry cobbler recipe is best served warm, straight from the preheated oven, with a scoop of ice cream melting into the top of the cobbler. The contrast of the cold, creamy vanilla ice cream with the warm, bubbling fruit is simply amazing. If you have leftovers (though that’s rare in my house!), store them in an airtight container in the refrigerator for up to three days. Reheat in the oven at 350°F for about 10 minutes to restore that golden brown crispness to the biscuit topping. You can also pop individual servings in the microwave for a quick next day treat.
