If you keep sourdough starter on the counter, you know the challenge: managing discard. Rather than toss it, transform it into a showstopping skillet cookie that’s crispy on the outside, chewy in the middle, and loaded with chocolate. This recipe delivers bakery-quality results in under 30 minutes of active time, making it perfect for weeknight desserts or impressing guests.
How to Make Sourdough Chocolate Chip Skillet Cookie
This recipe uses sourdough discard to create a tender, complex-flavored cookie base. The skillet method creates a thin, crispy crust while keeping the center soft.
Ingredients
- 1 cup sourdough discard (unfed starter at room temperature)
- 6 tablespoons unsalted butter, melted
- 1/2 cup packed brown sugar
- 1/4 cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon fine sea salt
- 3/4 cup chocolate chips
Method
Combine wet ingredients
In a large mixing bowl, whisk together your sourdough discard, melted butter, brown sugar, and granulated sugar until smooth and well combined. Add the egg and vanilla extract, whisking until the mixture is creamy and uniform. This creates the flavorful base that gives the cookie its distinctive tangy depth.
Mix dry ingredients separately
In a separate bowl, whisk together the flour, baking soda, and salt. Combining these dry ingredients separately prevents lumps and ensures even distribution of the leavening agent throughout the dough.
Fold dry into wet mixture
Pour the dry mixture into the wet ingredients and fold gently with a spatula until just combined. Do not overmix–lumpy batter is fine and will result in a more tender cookie. Overmixing develops gluten and creates a tougher texture.
Add chocolate chips
Fold the chocolate chips into the batter with a few gentle strokes. Reserve a small handful of chips to press into the top of the dough in the skillet for a rustic appearance.
Prepare and heat the skillet
Place a 10-inch cast iron skillet in a 375-degree Fahrenheit oven for 5 minutes to preheat. Remove carefully and brush the interior lightly with butter or oil to prevent sticking.
Transfer dough to skillet
Pour the cookie batter into the hot skillet, using a spatula to spread it into an even layer. The dough should reach toward the edges but doesn’t need to cover every corner. Top with reserved chocolate chips, pressing them gently into the surface.
Bake until edges set
Bake for 18-22 minutes, until the edges are golden brown and the center jiggles slightly when you gently shake the skillet. The cookie will continue cooking slightly after removal due to residual heat.
Cool and serve
Let the skillet cookie rest for 5 minutes before scooping. Serve warm with vanilla ice cream or whipped cream. The cookie will firm up as it cools but remain soft and chewy in the center.
- Use sourdough discard that has been sitting at room temperature for at least 2 hours–warm discard incorporates more easily and creates a fluffier texture.
- Don’t skip preheating the skillet; the hot surface creates the signature crispy crust while the interior stays chewy.
- If your cookie is browning too quickly on the edges, place a foil tent over the skillet for the last 5-8 minutes of baking.
What to Look For in Skillet Cookie Baking Equipment
- Cast iron skillet size and construction: A 10 to 12-inch skillet distributes heat evenly and prevents hot spots that burn edges. Look for smooth interior surfaces and lids or foil-friendly rims for temperature management during baking.
- Mixing bowl capacity and material: Use a 3-quart stainless steel or ceramic bowl that won’t react with acidic sourdough. A wider, shallower bowl makes folding dry ingredients easier than tall narrow bowls.
- Spatula design for gentle folding: A silicone or rubber spatula with a flat, wide blade is gentler on batter than wooden spoons and allows you to fold ingredients with minimal overmixing.
- Oven thermometer accuracy: Built-in oven dials are often inaccurate by 25+ degrees. A reliable thermometer ensures your skillet cookie bakes at the correct temperature for ideal texture.

Frequently Asked Questions
Can I use active sourdough starter instead of discard?
Yes, but the cookie will rise more and become cakey rather than crispy. Use discard that’s been sitting in the fridge for a few days, or reduce active starter by 2 tablespoons and add 2 tablespoons flour to match discard consistency.
Why do the edges brown faster than the center?
Cast iron edges touch the heat source directly while the center receives only indirect oven heat. Tent with foil after 15 minutes, or rotate the skillet halfway through baking if your oven has hot spots.
How do I know when the cookie is done baking?
The edges should be golden brown and firm to the touch, while the center jiggles slightly when you gently shake the skillet. Overbaking creates a cake texture; the residual heat finishes cooking the center as it cools.
Can I make this recipe in a regular baking pan instead of a skillet?
Yes, but the texture will differ. A 9-inch cake or pie pan produces a thicker, cakier cookie rather than the thin, crispy-edged result that makes skillet cookies special. For best results, use cast iron or a heavy metal skillet.
How should I store leftover skillet cookie?
Cover the skillet with foil or a kitchen towel and leave it on the counter for up to 2 days. Reheat briefly in a 300-degree oven for 5 minutes to restore crispness. For longer storage, transfer cooled pieces to an airtight container in the refrigerator for up to 5 days.
