Preheat: Set your oven to 350°F (176°C). Line a 9″x9″ baking dish with parchment paper for easy removal and clean-up later.
-
Melt: In a small saucepan over low heat, melt the butter. Stir in the chocolate chips, vanilla essence, and cocoa powder, mixing until everything is beautifully smooth. Let the mixture cool slightly.
-
Beat: In a large mixing bowl, use an electric mixer to beat the eggs, brown sugar, and white sugar together for about 7-10 minutes until the mixture becomes light and creamy. Add in the cooled chocolate mixture and sourdough discard, mixing gently on low speed until combined.
-
Fold: Carefully fold in the flour and salt with a spatula. Be gentle! You want a thick batter that’s well combined but not overworked.
-
Pour: Transfer the batter into the prepared baking dish, smoothing it out with the spatula to ensure an even bake.

Bake: Place your brownies in the oven and bake for 35-40 minutes. Check for doneness using a toothpick—it should come out with a few moist crumbs.

Easy Sourdough Discard Brownies Recipe FAQs
How do I know if my sourdough discard is still good to use?
Absolutely! Make sure your sourdough discard looks fresh—no signs of mold or dark spots, and it should have a pleasant, slightly tangy smell. If your discard has been sitting a while, you might want to give it a good stir to wake it up.
How should I store the brownies to keep them fresh?
To keep your brownies at their fudgy best, store them in an airtight container at room temperature for up to 3 days. If you place them in the refrigerator, they can last up to a week, though they might lose some of their gooeyness. Just make sure they’re tightly wrapped!
Can I freeze my Easy Sourdough Discard Brownies for later?
Very much so! To freeze, wrap each brownie individually in plastic wrap, then place them in a freezer-safe bag. They can be kept frozen for up to 3 months. When you’re ready to indulge, just thaw them in the fridge overnight, and then pop them in the microwave for 10-15 seconds to enjoy that fresh-out-of-the-oven taste!
What can I do if my brownies turned out too dry?
If your Easy Sourdough Discard Brownies came out dry, there are a few tricks to bring them back to life! Warm them up a bit and top with a scoop of vanilla ice cream or a drizzle of chocolate sauce to add moisture. For next time, avoid overbaking—aim for that toothpick to come out with just a few moist crumbs!
Are these brownies suitable for everyone, including those with allergies?
These brownies contain gluten from the flour and dairy from the butter, so they may not be suitable for those with celiac disease or dairy allergies. However, you can easily swap all-purpose flour for a gluten-free blend and use dairy-free butter to create a delicious alternative. Always check that your ingredients are safe for your dietary needs!
Can I use any other type of chocolate besides semi-sweet?
Of course! While semi-sweet chocolate chips are fantastic for these Easy Sourdough Discard Brownies, feel free to experiment with dark chocolate for a richer flavor or milk chocolate for a sweeter twist. Just remember that the type of chocolate will alter the overall sweetness and richness of your brownies!
