What You’ll Need for This Sourdough Discard Brownies Recipe:
Here’s the lineup of simple ingredients that keep this Sourdough Discard Brownies Recipe so accessible and budget-friendly:
- 1 cup sourdough discard (unfed or fed; room temperature)
- 1/2 cup (1 stick) unsalted butter (melted)
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/3 cup cocoa powder (unsweetened, good quality)
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 3/4 cup all-purpose flour
Don’t have cocoa powder on hand? Dutch-processed cocoa works well too in this sourdough discard dessert for a slightly richer taste.
If you want to make it extra chocolaty, you can add 1/2 cup chocolate chips or chopped nuts during mixing—this little tweak makes your easy sourdough brownie recipe even more special.
You can find all these ingredients at most grocery stores, and because this recipe uses straightforward pantry staples plus your discard, it’s economical to make anytime.
Quick tip: Measure your sourdough discard by volume to keep this recipe consistent. If you have your discard in the fridge, let it come to room temperature so it blends easily.
I always add a pinch more salt—it balances the sweetness and deepens the chocolate flavor in this moist sourdough brownies baking adventure.
Keep your cocoa powder stored in a cool, dry place to preserve its rich flavor. Butter is best melted fresh, but you can soften it gently in the microwave if you’re short on time.

How to Make This Sourdough Discard Brownies Recipe:
Let’s cook together—here’s how to turn your sourdough discard into a chocolatey delight!
- Preheat your oven to 350°F (175°C). Lightly grease an 8×8-inch baking pan or line it with parchment paper. This step helps ensure your brownies come out cleanly every time.
- Mix wet ingredients first. In a medium bowl, whisk together the sourdough discard, melted butter, granulated sugar, eggs, and vanilla extract until smooth. Your batter will be glossy and thick.
- Sift dry ingredients. Sift the cocoa powder, baking soda, salt, and flour into a separate bowl. This keeps lumps out of your batter and helps everything blend evenly.
- Combine wet and dry. Slowly add the dry ingredients to the wet mixture. Fold gently but thoroughly using a spatula. Don’t overmix—stop when no streaks remain to keep your brownies tender.
- Optional: add mix-ins. If you like, fold in chocolate chips or nuts here. This step is where you can personalize your sourdough discard brownies recipe to your taste.
- Pour batter into prepared pan. Spread it evenly with the spatula so it bakes uniformly. Your kitchen will start smelling amazing as the chocolate aroma fills the air.
- Bake for 25-30 minutes. The edges should pull away slightly from the pan, and a toothpick inserted in the center should come out with a few moist crumbs. If it’s too wet, give it a couple more minutes.
- Cool before cutting. Let your sourdough discard brownies recipe cool in the pan for at least 15 minutes to set up. If you try to slice them too early, you risk crumbly squares.
From start to finish, this Sourdough Discard Brownies Recipe takes about 45 minutes, including prep and bake time.
While the brownies bake, it’s a great chance to tidy your mixing bowls or prep your serving plates.
A helpful note: If your batter seems thicker than expected, that’s okay—sometimes discard hydrations vary. Just bake as directed; the moist sourdough brownies will still be a hit.
Looking for shortcuts? Melt your butter while preheating the oven to save a few minutes.
After baking this recipe many times, I’ve learned patience pays off. Waiting for the brownies to cool ensures the best texture.

You can also drizzle melted chocolate or caramel over the top for a festive touch if you want to impress without effort.
Leftovers (if you have any!) keep well stored in an airtight container for up to 3 days at room temperature or a week in the fridge. I sometimes use leftover brownies crumbled over yogurt or ice cream for a quick treat.
This sourdough discard dessert is perfect for family movie nights or sharing at a potluck where you want to bring something familiar but special.

Common Questions About This Sourdough Discard Brownies Recipe:
1. Can I make parts of this Sourdough Discard Brownies Recipe ahead of time?
Absolutely! You can mix the batter and keep it covered in the fridge for up to 24 hours. Just give it a gentle stir before baking.
2. What’s a good substitute for butter in this Sourdough Discard Brownies Recipe?
You can swap butter with the same amount of vegetable oil or coconut oil for a dairy-free version. Coconut oil adds a nice subtle flavor.
3. How can I adjust this Sourdough Discard Brownies Recipe for more or fewer people?
This recipe scales easily. For fewer brownies, halve the ingredients and bake in a smaller pan for less time. Double it for a crowd, using a 9×13 pan and watch the baking time closely.
4. What does sourdough discard bring to brownies?
Using sourdough discard in sweets like brownies adds a slight tang and improves the moist, tender texture. It’s a clever way to use discard beyond bread.
5. My brownies came out cakey instead of fudgy—what happened?
Check your baking time and flour measurement. Cakey brownies can result from overbaking or too much flour. This Sourdough Discard Brownies Recipe is designed for that fudgy texture, so slight tweaks can help.
6. Can I add other flavors to this recipe?
Yes! Vanilla is a staple, but you can add a little espresso powder to deepen the chocolate or a tiny bit of chili powder for warmth.
7. Do I need to use unfed discard or fed discard?
Both work well. I usually use discard that’s been sitting since feeding because it has less active yeast and adds wonderful flavor without extra rising.
I hope these answers make this Sourdough Discard Brownies Recipe clear and approachable. If you want more tips, you can check out Little Spoon Farm’s sourdough brownies take or Buttermilk by Sam’s version.
