Turn leftover sourdough discard into a gooey chocolate chip skillet cookie with crispy edges, browned butter, and a soft center that’s perfect with ice cream.
If you bake with sourdough regularly, you know how quickly discard can pile up. Instead of another loaf or batch of pancakes, this chocolate chip skillet cookie turns that extra starter into one of the easiest desserts you’ll make.
The sourdough discard adds a subtle tang that balances the sweet chocolate, while browned butter gives the cookie a rich caramel flavor that tastes like it took far more effort than it actually did. Baked in one skillet, it develops crisp golden edges and a soft, gooey center that’s perfect for serving warm with vanilla ice cream.
Why This Recipe Works
- Uses ½ cup sourdough discard without any extra fermentation.
- Browned butter creates deep caramel flavor.
- One-pan dessert with minimal cleanup.
- Crispy edges and a soft center every time.
- Great for active or unfed sourdough discard.

Notes
From Our Test Kitchen
The hardest part of this recipe isn’t making it. It’s waiting for it to cool. That short resting time helps the center finish setting while keeping everything perfectly gooey. If you scoop into it immediately, it’ll be delicious but much softer. We’ve also found that loosely covering the skillet with foil for the last part of baking makes all the difference. The top stays beautifully golden while the thick center bakes through without drying out. A few simple tricks make this recipe even more reliable.- Let refrigerated discard sit for 10–15 minutes if it’s very thick.
- Cool the browned butter before adding the eggs.
- Mix the flour in just until no dry streaks remain.
- Use a 10-inch skillet for a thicker cookie or a 12-inch skillet for a slightly thinner, crispier version.
- The center should feel soft but shouldn’t jiggle when gently shaken.

Ingredient Notes
Sourdough Discard
This recipe is very forgiving. Fresh discard, day-old discard, or discard straight from the refrigerator all work well. Since the baking soda provides the lift, your starter doesn’t need to be bubbly or active.
Browned Butter
Browning the butter creates toasted milk solids that give the cookie a rich caramel flavor you simply can’t get from melted butter.
The butter can go from golden and nutty to burnt fairly quickly. Once you see golden-brown specks collecting on the bottom of the pan and smell that nutty aroma, take it off the heat.
The butter will foam while browning, so the color underneath the foam is what you should watch.
Chocolate Chips or Chunks?
Both work beautifully.
- Chocolate chips hold their shape.
- Chocolate chunks create larger pools of melted chocolate throughout the cookie.
What kind of discard works best
We have this partly covered, but I’d make it more explicit:
You can use discard from a recently fed starter or discard that’s been stored in the refrigerator. For this recipe, the starter does not need to be active or bubbly. Just make sure your refrigerated discard is still good and doesn’t have an unpleasant or unusual smell.
How much does sourdough discard really matter?
The recipe uses ½ cup discard, but this isn’t a fermented sourdough recipe. The discard primarily contributes flavor, moisture, and a little acidity. The baking soda provides the leavening.
Easy Flavor Variations
Once you’ve mixed the dough, it’s easy to customize this skillet cookie. Most mix-ins are folded in right after the chocolate chips, while spices are added with the dry ingredients, so they distribute evenly throughout the dough.
Dark Chocolate Lovers
Replace the 1½ cups chocolate chips with 1½ cups dark chocolate chunks for a richer cookie.
Nutty Skillet Cookie
Add 1 cup chopped toasted pecans or walnuts along with the chocolate chips.
Salted Caramel
Mix in ¾ cup caramel bits and finish with flaky sea salt.
Double Chocolate
Reduce the flour from 2¼ cups to 2 cups. Replace that ¼ cup flour with ¼ cup unsweetened cocoa powder. Without reducing the flower, the dough gets a little too dry.
Cinnamon Spice
Add:
- 1 teaspoon cinnamon
- ¼ teaspoon nutmeg
- ¾ cup toasted pecans
S’mores Skillet Cookie
Mix in:
- 1 cup chocolate chips
- 1 cup mini marshmallows
- ½ cup crushed graham crackers
Add a few extra marshmallows during the last 5 minutes of baking so they toast beautifully.
Delicious Ways to Serve It
This skillet cookie is wonderful on its own, but it becomes even more special with simple toppings.
Classic Sundae. Vanilla ice cream plus warm chocolate sauce.
Salted Caramel. Caramel sauce and flaky sea salt.
Coffee Shop Style. Whipped cream with a dusting of cocoa powder.
Berry Dessert. Fresh strawberries or raspberries with whipped cream.
How to Store Leftovers
If you somehow have leftovers, they’re just as good the next day.
- Room temperature: Store covered for up to 3 days.
- Refrigerator: Up to 5 days.
- Freezer: Wrap individual slices and freeze for up to 3 months.
To reheat, microwave a slice for 15–20 seconds until warm and gooey again.
Creative Ways to Use Leftovers
Sometimes leftovers become the best dessert of all.
Ice Cream Sandwiches. Cool completely, cut into squares, and sandwich vanilla ice cream between two pieces.
Cookie Milkshakes. Blend a warm piece with vanilla ice cream and a splash of milk.
Skillet Cookie Trifle. Layer cookie pieces with whipped cream and fresh berries.
Breakfast Treat. Warm a small slice and serve alongside coffee. The browned butter flavor is especially delicious the next morning.
Does sourdough discard make this cookie taste sour?
Not really. The discard adds a slight tang that balances the sweetness, but the browned butter and chocolate remain the dominant flavors.
Can I use discard straight from the refrigerator?
Yes. Cold discard works perfectly.
Does my starter need to be active?
No. This recipe is designed specifically for sourdough discard.
Can I bake this in a baking dish instead?
Yes. A 9-inch round baking dish or oven-safe skillet works well, though cast iron gives the crispiest edges.
Why bake it covered for the last part?
Covering the skillet prevents the top from becoming too dark while allowing the thick center to finish baking.
Can I make the dough ahead of time?
Yes. Refrigerate the dough for up to 24 hours before baking. You may need to add a few extra minutes to the baking time.
Troubleshooting
My cookie seems underdone.
The center should be soft when it comes out of the oven. It continues setting during the 15–20 minute cooling period.
My edges got too dark.
Use foil a little earlier next time, around the 20-minute mark.
Homestead Kitchen Notes
One of my favorite things about keeping a sourdough starter is finding simple ways to use the discard instead of letting it go to waste.
This skillet cookie has become one of those recipes we make when we want something homemade without spending all afternoon in the kitchen. Browning the butter adds a little extra magic. And serving it warm from the skillet with a scoop of vanilla ice cream never lasts long around our table.
