How to Make Brown Butter Sourdough Chocolate Chip Cookies
1. Brown the Butter
Place the butter in a medium saucepan over medium heat.
Let the butter melt, then continue cooking while stirring frequently. It will begin to foam as the water evaporates, and golden-brown milk solids will start to form along the bottom of the pan.
Continue cooking until the butter develops a rich golden-brown color and smells nutty and fragrant.
Remove the pan from the heat immediately to prevent the butter from burning.
Pour the browned butter into a heatproof bowl and let it cool before making the cookie dough.
The butter should be cool enough that it won’t cook the egg when combined with the other ingredients.
2. Mix the Dry Ingredients
In a medium bowl, whisk together the flour, cornstarch, baking soda, and salt.
Whisk until everything is evenly combined, then set the mixture aside.
3. Combine the Brown Butter and Sugars
Add the cooled brown butter, brown sugar, and granulated sugar to a large mixing bowl.
Beat until the mixture is smooth and well combined.
The brown sugar helps keep the cookies moist and chewy, while the granulated sugar contributes to lightly crisp edges.
4. Add the Eggs and Sourdough Discard
Add the egg and egg yolk to the butter and sugar mixture.
Mix until well incorporated.
Add the vanilla extract and sourdough discard, then mix again until the mixture is evenly combined.
The batter may look slightly different or softer than traditional cookie dough because of the sourdough discard. That’s perfectly normal.
5. Add the Dry Ingredients
Gradually add the dry ingredients to the wet mixture.
Add about half of the flour mixture first and mix gently until mostly incorporated.
Add the remaining dry ingredients and continue mixing just until the flour disappears.
Avoid overmixing once the flour has been added. Mixing too much can develop the gluten and result in less tender cookies.
6. Fold in the Chocolate Chips
Add the chocolate chips to the cookie dough.
Use a spatula to gently fold them in until they are evenly distributed throughout the dough.
For extra chocolate in every bite, you can reserve a small handful of chocolate chips to press onto the cookies before baking.
7. Chill the Dough
Cover the bowl and refrigerate the dough for at least 10 minutes.
For deeper flavor and a more developed texture, refrigerate the dough for several hours or overnight.
Chilling helps reduce spreading and makes the dough easier to scoop.
If the dough has been refrigerated overnight, let it sit at room temperature for about 10–20 minutes before scooping if it is too firm.
8. Scoop the Cookies
Preheat your oven to 350°F (175°C).
Line a baking sheet with parchment paper.
Scoop approximately 2 tablespoons of dough for each cookie. Lightly roll each portion into a ball and arrange them on the prepared baking sheet.
Leave plenty of space between the dough balls because the cookies will spread as they bake.
9. Bake
Bake for approximately 12–14 minutes.
The edges should be lightly golden and set, while the centers should still look soft.
Don’t wait for the centers to become completely firm in the oven. The cookies will continue to set as they cool on the baking sheet.
Overbaking can take away the soft, chewy texture that makes these cookies so good.
10. Cool the Cookies
Let the cookies cool on the baking sheet for about 5 minutes.
Then transfer them to a wire rack to finish cooling.
For an extra chocolatey finish, gently press a few additional chocolate chips onto the tops while the cookies are still warm.
A light sprinkle of flaky sea salt is also delicious if you enjoy a sweet-and-salty flavor combination.
Tips for the Best Sourdough Discard Cookies
Cool the Brown Butter
Don’t rush this step. The browned butter should cool before it is mixed with the eggs. If it is too warm, it can affect the consistency of the dough and may cause the eggs to cook slightly.
Don’t Overmix the Dough
Once the flour is added, mix only until the ingredients come together. Overmixing can lead to tougher cookies.
Chill Before Baking
Even a short chilling period helps control spreading. For the best flavor, consider letting the dough rest in the refrigerator overnight.
Don’t Overbake
The centers should still look slightly soft when the cookies come out of the oven. They will continue cooking from the residual heat of the baking sheet.
Mix Your Favorite Chocolates
Try using a combination of dark, milk, and semi-sweet chocolate chips for a more interesting chocolate flavor.
Add Flaky Sea Salt
A small sprinkle of flaky sea salt over the warm cookies balances the sweetness and complements the brown butter and chocolate.
Make-Ahead Instructions
You can prepare the cookie dough ahead of time and keep it refrigerated until you’re ready to bake.
For longer storage, scoop the dough into individual portions and place the dough balls on a lined tray.
Freeze until firm, then transfer the frozen dough balls to a freezer-safe bag or airtight container.
When you’re ready to bake, place the frozen dough balls directly onto a parchment-lined baking sheet and allow a little additional baking time as needed.
How to Store
Store baked cookies in an airtight container at room temperature for about 3–4 days.
For longer storage, place the cookies in a freezer-safe bag or container and freeze them.
Allow frozen baked cookies to thaw at room temperature before serving.
For the best texture, you can warm thawed cookies briefly before enjoying them.
Serving Ideas
These cookies are delicious straight from the cooling rack, especially while they are still slightly warm.
Serve them with:
- Cold milk
- Coffee
- Hot chocolate
- Vanilla ice cream
- Melted chocolate drizzle
- Flaky sea salt
They also make a great homemade treat for cookie boxes, parties, school events, and holiday gatherings.
