Ingredients You’ll Need
Each ingredient in this recipe plays a crucial role in achieving the perfect texture and taste. From the creamy butter that builds richness to the tangy sourdough starter that adds complexity, everything is essential and thoughtfully chosen.
- Unsalted butter (½ cup / 113g): Provides a rich, smooth base for fudgy brownies and enhances chocolate flavor.
- Granulated sugar (1 cup / 200g): Sweetens the batter while adding structure and moisture.
- Brown sugar (½ cup / 100g): Adds a subtle caramel undertone and keeps the brownies tender.
- Unsweetened cocoa powder (¾ cup / 75g): The heart of chocolatey goodness, giving depth and intensity.
- Salt (½ tsp): Enhances flavors and balances sweetness perfectly.
- Baking powder (½ tsp): Gives a slight lift without sacrificing density, making brownies just right.
- Large eggs (2): Bind ingredients and deliver moisture, creating a smooth texture.
- Vanilla extract (1 tsp): Adds warmth and rounds out the chocolate notes beautifully.
- Sourdough starter, discarded or active (½ cup / 120g): The star ingredient that introduces a gentle tang and complexity to the brownies.
- All-purpose flour (½ cup / 60g): Provides structure while keeping these brownies delightfully soft.
- Chocolate chips or chunks (½ cup / 85g, optional): For those who adore gooey melted pockets of chocolate.
- Chopped walnuts or pecans (optional, ½ cup): Add a crunch and earthy flavor that complements the chocolate wonderfully.
- Caramel or peanut butter drizzle (optional): For a luscious finishing touch that surprises your palate.
- Flaky sea salt (optional): A sprinkle on top elevates the rich chocolate with a burst of saltiness.
How to Make Sourdough Brownies Recipe
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures a perfect baking environment from the get-go. Line an 8×8-inch pan with parchment paper and give it a light grease coating for easy removal later. A hot oven is the secret to that beautifully chewy crust.
Step 2: Melt the Butter and Cocoa
Melt your unsalted butter gently in a saucepan or microwave-safe bowl. Once melted, stir in the granulated sugar, brown sugar, and unsweetened cocoa powder until everything melds together into a luscious, smooth mixture. Set this aside to cool slightly—this step builds the base of your brownie’s deep chocolate flavor.
Step 3: Whisk in the Wet Ingredients
Once the chocolate mixture has cooled but is still fluid, whisk in the eggs one at a time, followed by the vanilla extract and the sourdough starter. The starter adds a subtle tang and moist crumb, making your brownies taste unique and utterly irresistible. Mix until everything is fully combined and silky.
Step 4: Incorporate the Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, and salt. Gently fold these dry ingredients into the wet mixture, just enough to combine. This careful mixing keeps the brownies tender and cakey without losing that signature fudgy bite.
Step 5: Add the Chocolate Chips
If you love extra bursts of melted chocolate, this is your moment to stir in the chocolate chips or chunks. They melt during baking, creating those delightful pockets of gooey richness that make brownies so addictive.
Step 6: Bake Until Perfect
Pour your batter into the prepared pan and spread it out evenly. Bake for 25 to 30 minutes. Peek inside around 25 minutes by inserting a toothpick—it should come out with a few moist crumbs clinging to it. Overbaking can dry out these gems, so keep a close eye!
Step 7: Cool Before Slicing
Once your brownies are baked, patience is key. Let them cool completely in the pan. This resting period allows the flavors to settle and the texture to firm up, making slicing easier and your brownies hold together beautifully.
Step 8: Serve & Savor
Now for the best part—eating! Enjoy these luscious sourdough brownies on their own or dress them up with powdered sugar, a drizzle of caramel, or a scoop of vanilla ice cream for an extra indulgent treat. You won’t regret it.

Garnishes
Simple garnishes like a light dusting of powdered sugar or a sprinkle of flaky sea salt take these brownies to the next level. The salt enhances the chocolate’s richness, while powdered sugar adds a pretty, sweet finish that’s perfect for guests or a special treat.
Side Dishes
Pair these brownies with scoops of creamy vanilla or coffee ice cream for contrast. Fresh berries or a dollop of whipped cream add brightness and texture. Even a cup of strong coffee or hot chai complements the sourdough’s slight tang and deep chocolate flavor remarkably well.
Creative Ways to Present
Try layering Sourdough Brownies between thick slices of homemade banana bread for an unforgettable dessert stack. You could also cut them into bite-sized squares and serve them on a dessert platter alongside nuts and dried fruits for a sophisticated treat board. The tangy twist makes these brownies stand out beautifully in any presentation.
Make Ahead and Storage
Storing Leftovers
Brownies keep well at room temperature in an airtight container for up to 3 days, and refrigeration can extend their freshness to about a week. Be sure to keep them sealed tightly to prevent drying or absorbing kitchen odors. Their moist, tender crumb stays intact thanks to the sourdough starter.
Freezing
Want to stock up? Wrap brownies tightly in plastic wrap and place them in a freezer-safe container or bag. They freeze beautifully for up to 3 months. When you’re ready for a sweet fix, let them thaw at room temperature for a few hours — they’ll taste just freshly baked!
Reheating
Warm brownies slightly in the microwave for 10-15 seconds or pop them in a low oven (about 300°F/150°C) for 5-7 minutes to revive that fudgy texture and soften them up. Adding a scoop of ice cream on top while still warm is a sure way to transform your snack into a decadent dessert.
FAQs
Can I use active or discarded sourdough starter in this recipe?
Yes! Both active and discarded sourdough starter work wonderfully here. Active starter will add a bit more rise and tang, while discarded starter brings subtle flavor without affecting the batter’s texture much. It’s a fantastic way to use up extra starter scraps.
What if I don’t have sourdough starter? Can I make these brownies without it?
While sourdough starter is key to creating the signature tang and texture in this recipe, you can substitute it with an equal amount of plain yogurt or buttermilk for a similar moist crumb. However, the unique sourdough flavor will be missing.
Should I use discarded starter right from feeding or should it be refrigerated?
Using refrigerated, unfed starter (often called discard) is best if you want a mild tang and won’t significantly affect rise. Freshly fed starter is more active and might add a bit more rising power and tanginess, so either works depending on your flavor preference.
Can I add nuts or other mix-ins to the Sourdough Brownies Recipe?
Absolutely! Chopped walnuts, pecans, or even dried fruit make excellent additions that add texture and flavor contrast. Just fold them into the batter at the same time as the chocolate chips for best distribution.
How fudgy versus cakey are these sourdough brownies?
These brownies strike a lovely balance between fudgy and cakey thanks to the sourdough starter and precise ingredient ratios. Expect a moist, tender crumb with a slightly chewy edge that melts in your mouth—the best of both worlds.
Final Thoughts
I can’t recommend this Sourdough Brownies Recipe enough if you want to treat yourself to something both familiar and exciting. The subtle tang from the sourdough elevates your classic brownies into a decadent, memorable dessert. Give it a go—you might just find this becomes your new favorite way to enjoy brownies!
