Ingredient Notes
When it comes to making this delicious cobbler, the ingredients are simple but flavorful. Let’s break down a few key components.
Sourdough Discard: This ingredient is a creative way to use leftover sourdough starter. It gives the topping an amazing texture and a subtle tang. If you don’t have sourdough discard, you can easily make your own or substitute with regular flour mixed with a bit of water to mimic the texture.
Swerve Sweetener: For those watching their sugar intake, Swerve is a fantastic sugar substitute that adds the sweetness without the glycemic impact. If you prefer another sweetener, feel free to use erythritol or monk fruit as an easy swap.
Fresh Blackberries: The star of this cobbler! Sweet, juicy, and bursting with flavor, they lend a vibrant color and taste. You can swap for other berries like blueberries or raspberries if you have them on hand.
Cornstarch: This is what helps thicken the blackberry filling, giving it that perfect gooey consistency. If you don’t have cornstarch, any similar thickening agent, like arrowroot powder, can work in a pinch.
Ingredients
For the topping:
- 1 cup sourdough discard (here is a sourdough starter that I use)
- 1/4 cup Swerve granulated sweetener
- 1/4 cup melted unsalted grass-fed butter
- 1/4 teaspoon sea salt
For the filling:
- 4 cups fresh blackberries
- 1/4 cup Swerve granulated sweetener
- 1 tablespoon lemon juice
- 1 tablespoon cornstarch

Tips for the Best Sugar-Free Sourdough Discard Blackberry Cobbler
- Use fresh berries. Fresh blackberries yield the best flavor. Frozen will work, but the texture may change slightly.
- Melt the butter slowly. If you microwave it, do so in short bursts to prevent it from splattering.
- Adjust sweetness to taste. Depending on the ripeness of your berries, you might want to tweak the amount of sweetener.
- Layer your topping evenly. Make sure to cover the berries completely for an even bake and flavor distribution.
How to Store Leftovers
Let your cobbler cool completely before storing. You can keep it covered in the fridge for up to 4 days. If you’d like to extend its life, freezing is also an option! Just wrap portions tightly in plastic wrap and aluminum foil for up to three months. To reheat, warm individual servings in the microwave or place in a preheated oven for the best texture.
Frequently Asked Questions
How long does it take to prep and can I make it ahead?
Prep time is about 15 minutes, with bake time around 30-35 minutes. You can prepare the filling and topping in advance, store them separately in the fridge, and then assemble and bake when you’re ready.
Can I substitute the blackberries?
Absolutely! You can swap with other berries like raspberries, blueberries, or even diced apples for different flavor profiles.

While the recipe contains butter and sourdough, you can easily make it gluten-free by using gluten-free oats or flour for the topping and substituting coconut oil or a dairy-free butter for the butter.
