This recipe is as simple as it gets! Follow these clear instructions to create perfect sourdough brownies that everyone will enjoy in no time.
Step 1
Preheat your oven to 350°F (175°C) and prepare your 8×8-inch baking pan by lining it with parchment paper. This not only prevents sticking but also allows for easy cleanup when you’re ready to slice the brownies.

In a large mixing bowl, whisk together the melted butter and granulated sugar until the mixture is smooth. Then, add your sourdough starter discard, eggs, and vanilla extract, mixing well to incorporate everything evenly.

Step 3
Sift in the cocoa powder, flour, and salt, stirring gently until just combined. Be careful not to overmix; this is key to keeping your brownies fudgy rather than cakey. Finally, fold in the chocolate chips for those delicious gooey pockets. Once your batter is ready, pour it into the prepared baking pan, spreading it evenly.
Now, pop it into the oven and bake for about 28 to 32 minutes or until a toothpick inserted into the center comes out with a few moist crumbs. Let the brownies cool in the pan, which will help them set up nicely. Once cool, slice them into squares and enjoy!
Common Mistakes to Avoid + Pro Tips for Success
When making these brownies, I want you to succeed on your first try. Fortunately, avoiding common mistakes is easy with a few tips from my kitchen adventures. I’ve made these errors before, and they can affect the taste and texture of your brownies.
Mistakes to Avoid
- Overmixing the batter: This can lead to tough brownies. Mix only until the dry ingredients are incorporated.
- Using cold ingredients: Ensure your butter and eggs are at room temperature to create a smooth batter.
- Not checking the baking time: All ovens are different, so start checking for doneness at 28 minutes to ensure perfectly fudgy brownies.
Tips for Success
- Use high-quality cocoa powder to enhance the chocolate flavor.
- Let the brownies cool completely in the pan for best slicing results.
- Storage: Keep brownies in an airtight container to maintain freshness.
The most important takeaway here is to enjoy the process and don’t stress about perfection.

Can I freeze these brownies?
Freezing is not recommended for these brownies as their texture may change. It’s best to store them in an airtight container at room temperature for up to one week.
