These brown butter sourdough chocolate chip cookies are everything you love in a classic cookie — but with a rich, toasty twist. Browned butter adds a deep, nutty flavor that pairs perfectly with melty pools of chopped chocolate, while the sourdough discard brings a slight tang and chewy texture that makes each bite unforgettable.
If you love a fudgy chocolate fix, try my brownie crumb bars too. And if you love brown butter as much as I do, don't miss my brown butter coconut pecan cookies and brown butter oatmeal cookies — or, for another sourdough cookie, my sourdough malted chai chocolate chip cookies.

Why You'll Love This Recipe
Deep brown butter flavor. Browning the butter adds a nutty, caramel-like richness you can't get any other way. Try it in my brown butter chocolate chipless cookies!
Tangy, chewy sourdough. The discard adds a subtle tang and that signature chewy texture, while using up your starter.
Melty chocolate pools. Chopped chocolate (instead of just chips) gives you dramatic, gooey puddles in every bite. If you love melty chocolate, you need to try my sourdough chocolate-stuffed peanut butter cookies!
A use for discard. Like my sourdough oatmeal cookies, these are a delicious way to use the starter you'd otherwise toss.
Make-ahead friendly. Chill or freeze the dough balls and bake fresh whenever the craving hits, just like my gingerbread latte cookies.

Ingredients You'll Need
- Unsalted butter — browned for deep, nutty flavor (salted works too; use less added salt).
- Brown sugar — dark brown for the chewiest texture and molasses depth.
- Granulated (cane) sugar — for structure and lightly crisp edges.
- Sourdough discard — room temperature preferred; adds tang and chew.
- Egg and egg yolk — the extra yolk adds richness and chew.
- Vanilla extract — rounds out the flavor.
- All-purpose flour, baking soda, and salt — the base and lift.
- Baking chocolate or chocolate bars — chopped, for melty pools (chips work too).
See recipe card for quantities.
Easy Substitutions & Variations
Dairy-free butter: Use a non-dairy stick butter or a neutral oil like coconut oil (adjust salt if your butter is salted). Note that it might not brown the same!
Dairy-free chocolate: An oat milk chocolate bar works great — or use a 12-oz bag of chocolate chips.
Walnut crunch: Add ½ cup chopped walnuts for a toasty bite that loves brown butter, like my brown butter sugar cookies.
Espresso boost: Mix in 1 teaspoon instant espresso powder to deepen the chocolate.
Peanut butter chip: Swap half the chocolate for peanut butter chips.
Double chocolate: Replace ¼ cup (30g) of the flour with cocoa powder and keep the chopped chocolate — a riff on my sourdough chocolate crinkle cookies.
Instructions
Step 1: Brown the butter over medium heat. You will start out with 170g of butter and by the end of the browning process you should have 140g.
Allow the butter to cool before mixing it with the brown sugar, cane sugar, vanilla, sourdough discard, egg and egg yolk.
Step 2: In the bowl of a stand mixer, mix together the butter and remaining wet ingredients. In a separate bowl, combine the dry ingredients and slowly incoorporate it into the wet mixture.
(adding all of the dry ingredients at once can cause the flour to fly out of the bowl when you start to mix it in if using a stand mixer, so best to do it slowly).
Step 3: Chop 8 ounces of chocolate and mix into your sourdough cookie dough.
Chill for 30 mins to an hour before baking at 350F for best results. (I've skipped chilling and they baked fine, however, chilling or resting the dough creates a deeper flavor with an even better texture in the end).
Step 4: Scoop into 2-tablespoon (40g) balls and bake at 350F for 10-12 mins until the edges are golden brown and the top looks just set.
10 minutes for unchilled cookie dough and 12 minutes for chilled cookie dough is what typically works for me.
Hint: Take them out of the oven when you start to see golden brown edges and the center is matte and domed (it shouldn't look shiny or raw on the outside). They will collapse a bit while cooling. Taking them out before they overbake is essential to making a perfectly chewy cookie!
Expert Tips
1. Watch the butter closely. It goes from golden to burnt fast — stir constantly and pull it the moment it's amber and smells nutty.
2. Weigh the butter after browning. Aim for ~140g; if you've lost more to evaporation, top it up with milk so the dough stays balanced.
3. Chop your own chocolate. A chopped bar gives you melty pools and thin shards a bag of chips can't match.
4. Don't skip the chill (if you can help it). Resting deepens the flavor and improves texture; chilled dough bakes thicker.
5. Pull them slightly underdone. Take them out when edges are golden and centers are matte and domed — they set as they cool. Overbaking is the enemy of chewy.
What Makes This Recipe Special?
This recipe layers three things that each make a great cookie, then combines them. First, browned butter, which toasts the milk solids for a nutty, caramel depth. Second, sourdough discard, which adds a subtle tang that balances the sweetness and contributes to a wonderfully chewy texture. And third, chopped chocolate instead of chips, for dramatic melty pools throughout.
Together they turn a familiar chocolate chip cookie into something with real depth and character — chewy, rich, and a little tangy. It's the same use-your-discard, build-the-flavor philosophy behind my sourdough chocolate peanut butter swirl cookies, and it makes for a cookie people remember.
Sourdough Cookie FAQs
Just faintly — the discard reads as a subtle tang and adds chew, not a sour, bready flavor.
No, but it's recommended. Chilling deepens flavor and gives a better texture; unchilled dough bakes a touch thinner.
Yes — it works the same here, since the discard is for flavor and texture rather than rise.
A chopped baking bar gives the best melty pools, but a 12-oz bag of chips works too.
Absolutely — chill it 1–2 days or freeze scooped dough balls and bake from frozen. For more chocolate cookies, try my chocolate chip cookies or the fudgy sourdough discard brownies.
Sourdough Cookie Troubleshooting Guide
| Problem | Cause | Fix |
|---|---|---|
| Burnt or bitter butter | Browned too long | Stir constantly; pull when amber and nutty |
| Cookies too flat | Dough warm, or lost too much butter | Chill the dough; top butter to 140g with milk |
| Dry, crumbly cookies | Overbaked | Pull when edges are golden and centers matte |
| Cakey, not chewy | Too much flour | Measure by weight (345g) |
| Chocolate sank to bottom | Chunks too large/heavy | Chop more evenly and fold gently |
Storage
Room temperature: Store in an airtight container for 3–5 days — they peak on days 2 and 3.
Freezer: Freeze pre-portioned dough balls or baked cookies for up to 6 months. Wrap in plastic and store in an airtight container to prevent flavor contamination.
