Chewy Brown Butter Sourdough Discard Cookies
If you keep a sourdough starter, you always need ways to use the discard. These chewy brown butter sourdough discard cookies turn that tangy leftover into the richest chocolate chip cookies you’ll make all week.
They have crisp edges, soft centers, and a deep nutty flavor from browned butter. You can mix the dough in one bowl and bake them the same day.
What Makes These Cookies So Good
The discard adds a subtle tang that balances the sweet chocolate and brown sugar. It also helps create a chewy texture because the fermented flour holds moisture.
Browning the butter deepens that flavor even more. You end up with cookies that taste like you spent hours on them, even though the hands-on work is minimal.
Ingredients
- ½ cup (113g) unsalted butter: you’ll brown this for a nutty depth
- 1 cup (200g) light brown sugar, packed: keeps the centers soft
- ¼ cup (50g) granulated sugar
- 1 large egg plus 1 egg yolk: for extra chew
- 1 ½ teaspoons vanilla extract
- ½ cup (120g) sourdough discard (unfed, straight from the fridge)
- 1 ¾ cups (220g) all-purpose flour: spooned and leveled
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup (170g) semi-sweet chocolate chips: or roughly chopped chocolate
Variations / Substitutions
- Swap the chocolate: use milk chocolate, dark chocolate, or white chocolate chips, or fold in a chopped chocolate bar for pockets of melty chocolate.
- Add nuts: ½ cup toasted walnuts or pecans add a crunchy contrast.
- Make it dairy-free: use a good vegan butter stick and brown it gently, then pick dairy-free chocolate chips.
- Boost the tang: let the dough cold-ferment in the fridge for 24 hours before baking; the sourdough flavor gets more pronounced.
Another great way to use discard is Sourdough Discard Banana Bread.
How to Make Sourdough Discard Cookies
Step 1: Brown the Butter
Melt the ½ cup butter in a light-colored saucepan over medium heat. Cook, swirling the pan often, until it foams, then turns amber with browned bits on the bottom, about 5 to 7 minutes.
The butter will smell nutty and look like dark honey. This step builds the backbone of flavor, so don’t rush it, but keep an eye on the color so it doesn’t burn. Immediately pour the browned butter into a heatproof bowl and let it cool while you gather the rest of the ingredients. You want it warm, not hot, when you mix the dough.
Step 2: Whisk the Wet Ingredients
Once the butter has cooled for a few minutes, add the 1 cup brown sugar, ¼ cup granulated sugar, the egg, the egg yolk, 1 ½ teaspoons vanilla, and the ½ cup sourdough discard. Whisk until the mixture is smooth and glossy, about 1 minute.
The mixture will look a little looser than typical cookie dough at this stage because of the discard. That changes as soon as you add the flour, so don’t worry if it seems thin right now.
Step 3: Stir in the Dry Ingredients and Chocolate
Sprinkle the 1 ¾ cups flour, ½ teaspoon baking soda, and ½ teaspoon salt over the wet mixture. Stir with a wooden spoon or stiff spatula just until no dry spots remain, about 30 seconds. Fold in the 1 cup chocolate chips.
Stop mixing as soon as the flour disappears. Overworking the dough can make the cookies tough. The dough will be soft and a bit sticky, with chocolate chips evenly scattered throughout.
Step 4: Portion and Chill the Dough
Scoop the dough into 1 ½ tablespoon portions and place them on a parchment-lined baking sheet. You should get about 24 dough balls. Cover the pan loosely and chill the dough for at least 30 minutes, or up to 24 hours if you want a stronger tang.
Chilling the dough solidifies the brown butter so the cookies spread less in the oven, giving you those thick, chewy centers. A 30 minute chill does the job, but an overnight rest lets the sourdough flavor develop even more.
Step 5: Bake the Cookies
Preheat the oven to 350°F (175°C) and line a second baking sheet with parchment. Arrange chilled dough balls an inch apart on the prepared sheets. Bake one sheet at a time for 10 to 12 minutes, until the edges are golden and the centers look slightly underdone.
Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack. Serve them warm, when the chocolate is still soft, or let them cool completely and store. They will keep their fresh-baked chew for days.
Tips for Chewy, Tangy Cookies
- Use a kitchen scale if you have one, especially for the flour and discard. Sourdough discard can vary in hydration, and 220 grams of flour always measures the same, while a cup can drift quite a bit.
- Brown the butter until it looks like the color of dark honey and smells nutty. If the milk solids turn black and smell acrid, the butter has burned and will taste bitter. Start over.
- Let the dough rest in the fridge for 24 hours if you love a pronounced sourdough tang. The flavor gets noticeably more complex.
- For extra-chewy cookies, swap the all-purpose flour with an equal weight of bread flour. The higher protein gives the cookies a sturdier chew.
Bake times by cookie size:
| Cookie Size | Bake Time |
|---|---|
| 1 tablespoon | 9–11 minutes |
| 1 ½ tablespoons | 10–12 minutes |
| 3 tablespoons | 13–15 minutes |
Storing and Freezing
Store cooled cookies in an airtight container at room temperature for up to 5 days. A slice of bread in the container keeps them soft. Freeze baked cookies in a zip-top bag for up to 3 months. You can also freeze unbaked dough balls on a sheet pan, then transfer them to a bag. Bake directly from frozen, adding 1 to 2 minutes to the time.
Frequently Asked Questions
Can I use active sourdough starter instead of discard?
Yes, active starter works. The cookies will still taste great, but the tang will be milder because the fermented flavor is less concentrated.
Why did my cookies spread into flat puddles?
The butter was likely too warm when you mixed the dough, or the dough didn’t chill long enough. Chilling solidifies the fat and prevents excess spread.
Can I make the dough ahead and freeze it?
Absolutely. Portion the dough into balls, freeze them solid on a tray, and store in a freezer bag for up to 3 months. Bake from frozen, adding about 2 minutes to the bake time.
Do I really need to brown the butter?
No, you can melt the butter and skip the browning. The cookies will still be soft and chewy, but you’ll miss the deep nutty flavor that makes these stand out.
How can I make these cookies gluten-free?
Replace the all-purpose flour with a high-quality 1-to-1 gluten-free flour blend. The texture will be slightly different but still delicious.
