Step‑by‑Step Instructions for Sourdough Brownie Cookies
Step 1: Preheat the Oven
Begin your baking adventure by preheating the oven to 350°F (175°C). While the oven warms up, take a baking sheet and line it with parchment paper to ensure your Sourdough Brownie Cookies can be easily removed after baking. This prep step will help you create deliciously perfect cookies with minimal sticking.
Step 2: Melt Chocolate and Butter
In a microwave-safe bowl, combine the dark chocolate chips and unsalted butter. Heat them in the microwave in 20-30 second intervals, stirring in between until the mixture is smooth and fully melted. This step is crucial for ensuring your cookies have a rich, fudgy base, setting the stage for that decadent chocolate flavor.
Step 3: Combine Ingredients
Once the chocolate and butter are melted and glossy, stir in the granulated sugar until well blended. Then, mix in the large egg and vanilla extract, beating until the mixture is thick and smooth. This is where your Sourdough Brownie Cookies start taking shape, so ensure everything is well combined for a delightful treat.
Step 4: Incorporate Sourdough
Now it’s time to add the sourdough discard to your mixture. Fold it into the batter, mixing gently until fully incorporated. This key ingredient brings a wonderful tang and moisture to your cookies, balancing out the sweetness and deepening the overall flavor profile of your Sourdough Brownie Cookies.
Step 5: Add Dry Ingredients
In a separate bowl, mix together the cocoa powder, all-purpose flour, baking powder, and salt. Slowly fold this dry mixture into your wet ingredients just until a thick batter forms. Take care not to overmix, as this will maintain that tender texture you love in Sourdough Brownie Cookies!
Step 6: Fold in Chocolate Chunks
Take your chocolate chunks and fold them into the thick cookie batter, ensuring they are evenly distributed. This addition will amplify the chocolate experience with every bite of your Sourdough Brownie Cookies. The chunks should add delightful pockets of melty chocolate goodness.
Step 7: Rest the Dough (optional)
For an optional step that enhances texture, let your cookie dough rest for about 15 minutes. This allows the flavors to meld and the dough to thicken slightly, creating an even richer final product. During this time, you can tidy up your workspace and prepare for baking.
Step 8: Scoop and Bake
Scoop tablespoon-sized portions of the dough onto your prepared baking sheet, leaving space between each to allow for spreading. Bake in your preheated oven for 10-12 minutes, or until the tops are shiny and the edges are set. This will give your Sourdough Brownie Cookies that iconic crackly top that’s so irresistible!
Step 9: Cool
Once baked, allow your Sourdough Brownie Cookies to cool on the baking sheet for about 10 minutes. This resting period helps them set perfectly before transferring them to a cooling rack. Afterward, they’ll be ready to enjoy, warm and full of fudgy chocolate bliss!

Make Ahead Options
These Sourdough Brownie Cookies are a fantastic choice for meal prep, saving you precious time on busy weeknights! You can prepare the dough up to 24 hours in advance; simply scoop the cookie portions onto the baking sheet and cover them tightly with plastic wrap, refrigerating until you’re ready to bake. If you want to prep even further ahead, you can freeze the cookie dough for up to 3 months. Just make sure to place the dough balls in an airtight container to maintain their quality. When you’re ready to bake, preheat the oven and bake straight from the freezer for an extra minute or two for fresh, fudgy cookies that will delight your family!

Expert Tips for Sourdough Brownie Cookies
-
Use Fresh Discard: Ensure your sourdough discard is fresh for the best flavor and moisture in your cookies. Stale discard may create an off-taste.
-
Room Temperature Ingredients: Allow butter, egg, and sourdough discard to reach room temperature before mixing to prevent the chocolate from seizing and to ensure a smoother batter.
-
Don’t Overmix: After adding the dry ingredients, mix just until combined. Overmixing can result in tough cookies instead of the tender, fudgy texture you desire.
-
Chill the Dough: For thicker cookies, consider refrigerating your dough for 30 minutes before baking. This helps the flavors develop and prevents excessive spreading.
-
Monitor Baking Time: Keep a close eye on your cookies while they bake; they’re ready when the edges are set, but the center still looks slightly underbaked for that perfect chewy texture.

Sourdough Brownie Cookies Recipe FAQs
What type of sourdough discard should I use?
Absolutely, using fresh sourdough discard is ideal! It adds the perfect balance of moisture and that delightful tang which enhances your cookies. If your discard has dark spots all over, it’s time to toss it out. Fresh discard ensures the best flavor and texture in your Sourdough Brownie Cookies.
How should I store leftover cookies?
Store your Sourdough Brownie Cookies in an airtight container at room temperature for 3-5 days for optimal freshness. If they start to harden, a slice of bread in the container can help keep them soft. You can also refrigerate them for up to a week; just remember to let them come to room temperature before enjoying.
Can I freeze the dough before baking?
Yes! Freezing the cookie dough is a great option for quick treats on demand. Scoop tablespoon-sized portions of the dough and place them on a baking sheet lined with parchment. Freeze until solid, then transfer to an airtight container or freezer bag. They can be stored for up to 3 months. When ready to bake, you can bake them straight from the freezer; just add a couple of extra minutes to the baking time.
What should I do if my cookies spread too much?
If your Sourdough Brownie Cookies spread too much while baking, there are a few steps you can take next time. First, ensure you’ve chilled the dough for about 30 minutes before scooping it onto the baking sheet. Also, check that you’re using the right flour-to-liquid ratio, and consider adding a little more flour if necessary. Lastly, make sure you’re not overmixing the dough after adding dry ingredients, as this can affect texture and spread.
Are these cookies suitable for people with nut allergies?
Definitely! The Sourdough Brownie Cookies can be made nut-free easily by omitting any nuts from the recipe and ensuring that facilities or ingredients don’t have cross-contamination with nuts. They can be enjoyed by everyone, but do double-check any chocolate chunks or additives to ensure they’re safe for those with specific allergies.
