Sourdough Chocolate Chip Cookies Recipe
Ingredients
- ½ cup (113g) unsalted butter, melted
- ½ cup (100g) brown sugar
- ¼ cup (50g) granulated sugar
- ½ cup (120g) sourdough discard (unfed)
- 1 large egg
- 1 teaspoon vanilla extract
- 1 ½ cups (180g) all-purpose flour
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup (180g) chocolate chips
Instructions
- Mix Wet Ingredients
In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth. Add the sourdough discard, egg, and vanilla extract, then mix until well combined.

- Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, and salt.

- Make the Dough
Gradually add the dry ingredients to the wet mixture, stirring until just combined. Fold in the chocolate chips.



- Chill the Dough
Cover and refrigerate for at least 30 minutes. This helps develop flavor and prevents the cookies from spreading too much. - Preheat & Bake
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Scoop the dough into 1 ½-inch balls and place them on the baking sheet, leaving space between them.

- Bake & Cool
Bake for 10-12 minutes, or until the edges are golden brown but the centers look slightly underdone. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack.

Tips for the Best Sourdough Cookies
- Use room temperature ingredients – Helps the dough mix evenly.
- Chill the dough – This improves flavor and texture.
- Don’t overbake – The cookies continue to cook as they cool.
Storage & Freezing
- Store cookies in an airtight container at room temperature for up to 5 days.
- Freeze cookie dough in scooped portions and bake straight from frozen (just add 2 extra minutes to the bake time).
