Ingredients for Sourdough Discard Brownies
Alright, let’s gather our goodies! Here’s what you’ll need for these crazy-good sourdough discard brownies. I always measure my ingredients *before* I start – it just makes life easier, you know?
- 1 cup all-purpose flour (I don’t usually sift, but hey, you do you!)
- ½ cup unsalted butter, melted (yes, real butter is a MUST!)
- 1 cup granulated sugar
- ½ cup sourdough discard (the star of the show!)
- ½ cup unsweetened cocoa powder
- 2 large eggs
- 1 teaspoon vanilla extract (don’t skimp on the good stuff!)
- ½ teaspoon baking soda
- ¼ teaspoon salt
And if you’re feeling fancy, throw in some chocolate chips or chopped walnuts. I won’t judge!

How to Make Sourdough Discard Brownies
Okay, here’s the lowdown on how to make these amazing sourdough discard brownies. Don’t worry; it’s way easier than it sounds! Just follow these steps, and you’ll be sinking your teeth into chocolatey goodness in no time.
- Preheat like you mean it! Crank that oven to 350°F (175°C). Seriously, don’t skip this step or your brownies will be sad.
- Prep your pan. Grease and flour an 8×8 inch baking pan. Or, if you’re lazy like me, line it with parchment paper with a bit of overhang. Makes cleanup a breeze!
- Melt that butter. In a microwave-safe bowl, melt the butter. Careful, don’t let it explode! Let it cool for a minute.
- Mix the wet stuff. In a large bowl, whisk together the melted butter, sugar, and sourdough discard. Get it nice and smooth!
- Add the eggs and vanilla. Beat in the eggs one at a time, then stir in the vanilla extract. Mmm, that vanilla smell!
- Dry ingredients time! In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. This makes sure everything’s evenly distributed.
- Combine! Gradually add the dry ingredients to the wet ingredients, mixing until *just* combined. Don’t overmix! Overmixing = tough brownies. And nobody wants that.
- Pour into the pan. Pour the batter into your prepared pan and spread it evenly.
- Bake it, baby! Bake for 25-30 minutes. The edges will look set, but the center should still be a little soft. Remember, we’re going for fudgy.
- Cool completely (if you can wait!). Let the brownies cool in the pan for at *least* 30 minutes before cutting. I know, it’s torture, but trust me, it’s worth it.
- Slice and devour! Cut into squares and enjoy! And maybe share… but no pressure!

Tips for the Best Sourdough Discard Brownies
Want to take these brownies from “good” to “OMG, these are the best brownies EVER?” Here are a few of my top tips that guarantee chocolatey success every time!
- Don’t. Overbake. Seriously, this is brownie rule #1. Undercooking is way better than overcooking when you want that perfect fudgy center. Start checking for doneness around 25 minutes.
- Go for the good stuff! Use high-quality cocoa powder. Trust me, it makes a difference in the richness of the flavor. You want it dark, you want it intense, you want it to make your tastebuds sing!
- Patience, grasshopper! Let those brownies cool *completely* before cutting. I know, it’s hard, but if you cut them while they’re still warm, they’ll be a gooey mess. And while a gooey mess is still delicious, it’s not quite as pretty.
Sourdough Discard Brownies: Variations to Try
Okay, so you’ve mastered the basic sourdough discard brownie? Awesome! Now let’s get a little wild and try some fun variations. Because who says brownies have to be boring?
- Nutty Delight: Stir in ½ cup of chopped walnuts or pecans into the batter before baking. That little crunch? Adds *amazing* texture!
- Chocolate Chunk Heaven: Fold in ½ cup of your favorite chocolate chips (milk, dark, white – whatever floats your boat!) after mixing the batter. Every bite is a little explosion of chocolatey goodness!
- Peanut Butter Swirl: When you pour the brownie batter into the pan, dollop spoonfuls of peanut butter over the top. Then, use a knife or toothpick to swirl it around. Hello, dreamy peanut butter swirls!
Storing Your Sourdough Discard Brownies
Alright, so you’ve baked these amazing sourdough discard brownies… and you *somehow* have leftovers? You’re a stronger person than I am, I’ll tell ya that! But okay, here’s how to keep ’em fresh (or, you know, *fresher*) if you can resist eating them all right away.
- Room Temperature: Store your brownies in an airtight container at room temperature for up to 3 days. They’ll stay nice and fudgy… if they last that long!
- Freezer Time: Wanna make ’em last even longer? Wrap individual brownies tightly in plastic wrap (or foil) and pop them in a freezer bag. They can hang out in the freezer for up to 2 months. When you’re ready for a treat, just thaw ’em at room temperature or nuke ’em for a few seconds. Warm brownies? Yes, please!
FAQ About Sourdough Discard Brownies
Got questions about these amazing sourdough discard brownies? Don’t worry, I’ve got answers! Here are a few of the most common things people ask me:
What *is* sourdough discard, anyway?
Okay, so sourdough discard is basically the part of your sourdough starter that you *don’t* use when you’re feeding it. You know, when you scoop some out to make room for fresh flour and water? That’s discard! And it’s full of flavor, so don’t throw it away (use it in these brownies!).
Can I use a different type of flour?
Yep, definitely! All-purpose flour is my go-to, but you could also try using whole wheat flour for a slightly nuttier flavor. Just keep in mind that it might make the brownies a bit denser. I haven’t tried it with gluten-free flour yet, but if you do, let me know how it turns out!
Can I add chocolate chips? (Seriously, can I?)
Um, YES! Did you even have to ask? I mean, chocolate chips are *always* a good idea. Throw in a half cup (or more!) of your favorite kind. Dark chocolate, milk chocolate, white chocolate… go wild!
How long do these sourdough discard brownies last?
If you store them in an airtight container at room temperature, they’ll stay fudgy and delicious for up to 3 days. But let’s be real, they’ll probably be gone way before then! If not, you can always freeze them for later – see my storing tips above!
Are these brownies healthy?
Healthy is a strong word, y’all! These *sourdough discard brownies* are definitely a treat! They’re rich, decadent, and oh-so-delicious. So, maybe not your everyday snack… but definitely a perfect indulgence! But hey, at least you’re using up that sourdough discard instead of tossing it, right?
