Step‑by‑Step Instructions for Sourdough Brownie Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While your oven warms up, line a baking sheet with parchment paper, ensuring it’s ready to catch all those gooey Sourdough Brownie Cookies. This setup will help prevent the cookies from sticking and make cleanup a breeze.
Step 2: Melt Chocolate and Butter
In a microwave-safe bowl, combine dark chocolate chips and unsalted butter. Melt them together in 20-30 second intervals, stirring after each interval until smooth and glossy. This creamy mixture serves as the base of your cookie batter, enriching the flavor profile of your Sourdough Brownie Cookies.
Step 3: Combine Sugar, Egg, and Vanilla
Next, whisk in granulated sugar until the mixture appears glossy. Then, add a large egg and vanilla extract, stirring until everything is thick and smooth. This step is essential in creating the rich, fudgy texture of the cookies, ensuring they are wonderfully decadent.
Step 4: Incorporate Sourdough Discard
Now, gently stir in the sourdough discard, ensuring it’s well combined with the chocolate mixture. The sourdough adds a delightful tang, enhancing the overall flavor of your Sourdough Brownie Cookies, creating a balance between sweetness and depth.
Step 5: Mix Dry Ingredients
In a separate bowl, whisk together unsweetened cocoa powder, all-purpose flour, baking powder, and salt. Gradually fold this dry mixture into the wet ingredients until a thick batter forms. Be careful not to overmix; you want to keep your cookies tender and chewy.
Step 6: Add Chocolate Chunks
Once the batter is formed, fold in chocolate chunks for added texture and bursts of delicious chocolate throughout your cookies. This not only enhances the chocolate flavor but also contributes to that irresistible fudgy experience in each bite of your Sourdough Brownie Cookies.
Step 7: Let Dough Rest (Optional)
For an even better texture and flavor, consider letting the batter rest for about 15 minutes. This optional step allows the ingredients to meld together more seamlessly, resulting in an even richer taste in your final cookies.
Step 8: Scoop and Shape the Cookies
Using a tablespoon, scoop out portions of the cookie dough and place them on the prepared baking sheet, leaving space between each scoop. This step ensures that your Sourdough Brownie Cookies have room to spread and form perfectly chewy edges while baking.
Step 9: Bake the Cookies
Bake the cookies in the preheated oven for 10-12 minutes, or until the tops are shiny and crackled, and the edges are set. This short baking time will help maintain the fudgy goodness of your Sourdough Brownie Cookies while giving them a delightful crust.
Step 10: Cool the Cookies
After baking, allow the cookies to cool on the baking sheet for 10 minutes. This cooling time helps them firm up before you transfer them to a cooling rack. The result will be soft and chewy cookies that are irresistible and perfect for sharing or enjoying on your own.

Sourdough Brownie Cookies Recipe FAQs
What should I look for when selecting sourdough discard?
Absolutely, when choosing sourdough discard, it’s best to use fresh discard for optimal flavor. Look for a discard that hasn’t been in the fridge too long, ideally less than 1 week old. It should have a pleasant smell and be free from any dark spots or liquid separation, ensuring you get that wonderful tang without any off-flavors.
How do I store leftover Sourdough Brownie Cookies?
For the best results, store your Sourdough Brownie Cookies in an airtight container at room temperature for up to 3 days. If you’d like to keep them longer, consider freezing the cookies. Just make sure they are completely cooled before sealing them up to maintain their softness.
Can I freeze the cookie dough for later use?
Very much so! To freeze your Sourdough Brownie Cookie dough, scoop dough portions onto a baking sheet lined with parchment paper, and freeze until firm (about 1-2 hours). Once frozen, transfer the dough balls to a freezer-safe bag or container, and they can last up to 3 months. When ready to bake, no need to thaw—just pop them in the oven for a couple of extra minutes!
What should I do if my cookie dough seems too dry?
If you find your Sourdough Brownie Cookie dough is too dry, don’t fret! Simply add a teaspoon of milk or water at a time, mixing gently until you reach the desired consistency. Remember, the dough should be thick but still hold together; it shouldn’t crumple apart.
Are Sourdough Brownie Cookies suitable for people with nut allergies?
Yes, these cookies can absolutely be made nut-free! Just be cautious when selecting your chocolate chips to ensure they are also nut-free. If you’d like to add texture, consider using seeds or oats as an alternative. Always check ingredient labels if serving to someone with allergies to ensure safety.
What is the best way to know when the cookies are done baking?
You’ll know your Sourdough Brownie Cookies are ready when the tops look shiny and crackled, and the edges are set yet still soft in the center. The baking time is key; generally, they should take about 10–12 minutes in a preheated oven. If you gently press the center, it should bounce back slightly but still feel soft. This ensures they’ll have that perfect fudgy texture!
