Sourdough brownies. Yeah, you heard me right! If you’re deep into sourdough baking (or just getting started), this recipe is going to change the way you look at your sourdough starter. Whether you’ve got a jar of bubbly goodness on your counter or some discard in the fridge you’re trying to use up, these brownies are the perfect answer to that eternal question: What else can I do with sourdough?
Let’s break it down: sourdough brownies combine the rich, fudgy decadence of classic brownies with a little tangy twist, thanks to the sourdough starter. It sounds fancy, but don’t worry—it’s super easy to pull off. Even if you’re not a pro baker, I’ve got you covered with all the tips, tricks, and answers to questions you didn’t even know you had.
Why Sourdough Brownies?
Okay, real talk: I love sourdough bread, but sometimes, I don’t want another loaf (or have time to bake one). Enter these brownies. They’re a lifesaver for using up starter or discard without letting it go to waste. Plus, the sourdough adds an extra layer of flavor you just can’t get from regular brownies.
The tanginess from the sourdough isn’t overpowering—it’s subtle, like a secret ingredient that makes people go, “Wow, what’s in these?!” And let’s not forget the texture. They’re fudgy, chewy, and soft with a perfectly crackly top.

Ingredients You’ll Need
Don’t worry; this recipe doesn’t call for anything wild. Most of these ingredients are probably already in your kitchen. Here’s what you’ll need:
- Butter (unsalted, because we want full control over the saltiness)
- Chocolate (go big here—dark chocolate is perfect for that rich flavor)
- Granulated sugar (for sweetness and that shiny top)
- Brown sugar (because it adds a bit of chewiness)
- Eggs (the fresher, the better)
- Vanilla extract (don’t skimp on this—it makes all the difference)
- All-purpose flour (just a bit, so they don’t get cakey)
- Cocoa powder (unsweetened, please!)
- Salt (balances out all that sweetness)
- Sourdough starter (either bubbly or discard works)
Step-by-Step Instructions
1. Prep Your Ingredients
First things first: preheat your oven to 350°F and grease an 8×8-inch baking pan. If you have parchment paper, line the pan with it for easy brownie removal later.
2. Melt the Butter and Chocolate
In a microwave-safe bowl (or over a double boiler if you’re feeling fancy), melt the butter and chocolate together. Stir until smooth. Pro tip: Don’t overheat the chocolate, or it’ll seize up.
3. Mix in the Sugars
Once the butter and chocolate are smooth, mix in the granulated sugar and brown sugar. This step helps create that signature crackly top.
4. Add the Eggs and Vanilla
Whisk in the eggs one at a time, then stir in the vanilla extract. The mixture should be glossy and thick by now.
5. Incorporate the Sourdough Starter
Here’s the fun part—add your sourdough starter to the mix. It might feel a little weird to mix bread starter into brownies, but trust me, it works. Stir until fully combined.
6. Fold in the Dry Ingredients
In a separate bowl, sift together the flour, cocoa powder, and salt. Gently fold this mixture into the wet ingredients. Don’t overmix; you want everything just combined.
7. Pour and Bake
Pour the batter into your prepared pan and spread it out evenly. Pop it in the oven and bake for 30–35 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs.
8. Cool and Serve
Let the brownies cool in the pan for at least 20 minutes before cutting them into squares. I know, it’s hard to wait, but trust me—it’s worth it.
Tips for the Best Sourdough Brownies
- Use discard or active starter. Either works, but discard is my favorite for brownies. It adds just the right tang without making the batter too runny.
- Go heavy on the chocolate. The better the chocolate, the better the brownies. Dark chocolate chips or bars with 60–70% cocoa are perfect.
- Don’t overbake! This is the golden rule for brownies. Pull them out when they’re just barely set in the center—they’ll firm up as they cool.
- Add-ins are fair game. Want to throw in some walnuts, chocolate chunks, or even a sprinkle of flaky sea salt? Go for it.
Why Sourdough Starter Works in Brownies
If you’re wondering what sourdough is doing in a dessert recipe, let me explain. Sourdough starter is essentially a mix of flour and water that’s fermented with wild yeast. When you add it to brownies, it brings:
- Extra flavor. The tangy notes balance the sweetness, making these brownies taste more complex.
- Better texture. The starter helps keep the brownies moist and fudgy.
- Less waste. Using discard in recipes like this is a genius way to avoid throwing it out.
Sourdough Brownies: A Game-Changer for Your Dessert Rotation
If you’ve been baking for a while, you know how many ways sourdough starter can be used—bread, crackers, pancakes. But have you thought about dessert? That’s where sourdough brownies come in and completely steal the show. These brownies aren’t just another dessert; they’re a conversation starter. Once people taste them, they’ll be asking for the recipe (or begging you to make them again).
Sourdough brownies bring something unique to the table. The starter’s natural tang adds depth to the flavor, making the sweetness more balanced. It’s the perfect example of how a small change in ingredients can make a huge difference in taste. Think of them as the upgraded version of your regular brownies, with a rich chocolatey vibe that’s anything but ordinary.
How Sourdough Brownies Are Different
What makes sourdough brownies different from the boxed mix or traditional recipes we grew up with? The sourdough starter is the secret weapon. Here’s why:
- Flavor Boost: The slight tang from the starter elevates the chocolate flavor, making it deeper and more intense. It’s like adding a splash of coffee to brownie batter—but better.
- Homemade Magic: Sourdough brownies taste homemade in the best way. The texture and flavor remind you they’re crafted from scratch, not some pre-packaged mix.
- Customizable to Your Starter: Each sourdough starter is unique, which means every batch of brownies has a little personality.
Making Sourdough Brownies Part of Your Routine
Let’s be real: life gets busy, and sometimes baking can feel like a chore. But sourdough brownies? They’re quick, easy, and worth every second. Even if you’re not baking sourdough bread weekly, you can keep a starter in your fridge and pull it out for these brownies. In fact, this recipe might just become your go-to reason to keep a starter alive.
You could even start a new weekend tradition. Imagine this: Saturday mornings for bread and sourdough brownies in the afternoon. Or maybe these brownies are your new “I need a pick-me-up” dessert during the week. Trust me, they’re as comforting as they are indulgent.
Sourdough Brownies Are Great for Sharing
Baking sourdough brownies is also a fantastic way to share your love of sourdough with others. Not everyone is into making bread (it’s a commitment, after all), but almost everyone loves brownies. When you bring a tray of these to a potluck, picnic, or office gathering, they’ll disappear in no time.
And because these brownies are unique, they’re a great conversation starter (pun intended). When someone asks, “What’s the secret ingredient?” you get to casually say, “Oh, it’s sourdough starter,” and watch their jaws drop.
A Healthier Indulgence (Sort Of)
Okay, let’s not kid ourselves—these are brownies, not kale chips. But using sourdough starter adds a little more nutritional value than you’d get from a basic mix. Sourdough ferments the flour, which can make it easier to digest. If you’re already into sourdough for its health benefits, these brownies are an indulgent yet smarter way to treat yourself.
Also, because these brownies are rich and flavorful, you don’t need a huge piece to feel satisfied. A small square with a cup of coffee or a glass of milk hits the spot.
Sourdough Brownies for All Occasions
Whether it’s a birthday party, a holiday treat, or just a lazy Sunday afternoon, sourdough brownies are versatile enough to fit the bill. They’re fancy enough to impress but simple enough to make anytime.
I’ve even made these brownies for Valentine’s Day (with a sprinkle of red heart-shaped candies) and Thanksgiving (with a dollop of whipped cream). They’re truly the little black dress of desserts—perfect for every situation!
FAQs
The sourdough starter adds a slight tang that balances the sweetness of the brownies, creating a more complex flavor. It also contributes to a moist, fudgy texture that sets these apart from regular brownies.
Yes, you can! Sourdough discard from the fridge works perfectly in this recipe. There’s no need to bring it to room temperature—it will mix into the batter just fine.
For this recipe, 1/2 cup of sourdough starter is ideal. It provides enough tang without overpowering the brownies.
The sourdough flavor is subtle and doesn’t make the brownies taste sour. Instead, it enhances the chocolate flavor, giving the brownies a richer, more balanced taste.
If you want a gluten-free version, you’ll need a gluten-free sourdough starter and a 1:1 gluten-free flour blend to replace the all-purpose flour. The results might be slightly different, but still delicious!
Conclusion
Sourdough brownies are more than just a dessert—they’re a genius way to use up your sourdough starter while making something truly delicious. With their fudgy texture, rich chocolate flavor, and a subtle tang that sets them apart from classic brownies, they’re bound to become your new favorite treat.
Whether you’re looking for a way to avoid wasting sourdough discard or just want to surprise your family with a unique dessert, these brownies check all the boxes. They’re easy to make, endlessly customizable, and perfect for any occasion—be it a quiet night in or a big gathering with friends.
So, grab that sourdough starter (even if it’s been hanging out in the back of your fridge), whip up a batch, and prepare to be amazed. Once you take a bite, you’ll wonder why you didn’t try sourdough brownies sooner. Trust me, one taste, and you’ll be hooked!
Happy baking—and don’t forget to share these with someone who loves chocolate as much as you do!
