Ingredients
Makes about 18–20 cookies
- ½ cup (115 g) unsalted butter, softened
- ¾ cup (150 g) brown sugar
- ¼ cup (50 g) granulated sugar
- ½ cup (120 g) sourdough discard (unfed starter)
- 1 large egg
- 1 teaspoon vanilla extract
- 1 ½ cups (190 g) all-purpose flour
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup (170 g) chocolate chips or chocolate chunks
Optional additions:
- ½ cup chopped walnuts or pecans
- A sprinkle of flaky sea salt on top
Preparation Time
- Prep time: 15 minutes
- Chill time: 30 minutes (recommended)
- Bake time: 10–12 minutes
- Total time: about 1 hour
Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 350°F (175°C).
Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking.
2. Cream the Butter and Sugars
In a large mixing bowl, combine the softened butter, brown sugar, and granulated sugar.
Using a hand mixer or whisk, beat the mixture until it becomes light and creamy. This step helps create a tender cookie texture.
3. Add the Wet Ingredients
Mix in the sourdough discard, egg, and vanilla extract.
Stir until the mixture is smooth and fully combined. The sourdough discard will add moisture and a slight tangy flavor that complements the sweetness of the cookie.
4. Combine the Dry Ingredients
In a separate bowl, whisk together:
- Flour
- Baking soda
- Salt
Gradually add the dry ingredients to the wet ingredients, mixing until a soft cookie dough forms.
5. Fold in the Chocolate Chips
Add the chocolate chips and gently fold them into the dough.
If you like extra chocolate in every bite, feel free to add a few additional chocolate chunks.
6. Chill the Dough (Optional but Recommended)
For thicker cookies and deeper flavor, cover the dough and chill it in the refrigerator for 30 minutes.
Chilling also helps prevent the cookies from spreading too much during baking.
7. Shape the Cookies
Scoop about 1½ tablespoons of dough and roll into balls.
Place them on the prepared baking sheet, leaving about 2 inches of space between each cookie.
8. Bake the Cookies
Bake the cookies at 350°F (175°C) for 10–12 minutes.
The edges should be golden brown while the centers remain slightly soft.
9. Cool the Cookies
Allow the cookies to cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.
The cookies will continue to firm up slightly as they cool.
Tips for the Best Cookies
Use Room Temperature Ingredients
Butter and eggs mix more easily when they are at room temperature, creating a smoother dough.
Don’t Overbake
Cookies may look slightly underbaked in the center when removed from the oven, but they will set as they cool.
Add a Sprinkle of Sea Salt
A small pinch of flaky sea salt on top enhances the chocolate flavor and balances the sweetness.
Try Different Chocolate
Dark chocolate chunks, milk chocolate chips, or even white chocolate chips work beautifully in this recipe.
Flavor Variations
These cookies are easy to customize depending on your taste preferences.
Double Chocolate
Add 2 tablespoons cocoa powder to the dough and increase chocolate chips for extra richness.
Nutty Chocolate Cookies
Mix in chopped walnuts, pecans, or almonds for added crunch.
Salted Caramel
Add small caramel pieces along with the chocolate chips for a gooey twist.
Espresso Chocolate
Add ½ teaspoon espresso powder to enhance the chocolate flavor.
