Ultimate Sourdough Chocolate Chip Cookies (Soft & Chewy)!
One of my favorite childhood memories is watching my grandmother bake chocolate chip cookies on a chilly afternoon. The sweet, buttery aroma filled the kitchen as I eagerly waited for them to cool.
Years later, that scent still brings me comfort. Now, after many experiments with sourdough baking, I’ve perfected a recipe that combines the nostalgia of classic chocolate chip cookies with the rich depth of sourdough.

The result? A cookie that’s soft and chewy with crispy edges, just the right amount of sweetness, and a subtle tanginess from the sourdough.
These easy-to-make cookies are a delicious way to use up sourdough discard while creating something truly special.

Prep & Cook Time
| Activity | Time |

| Prep Time | 15 minutes |
| Chill Time (optional for better texture) | 30 minutes |
| Cook Time | 12-15 minutes |
| Total Time | 45-60 minutes |
Step-by-Step Instructions
- Brown half the butter: Melt ½ cup butter over medium heat until golden brown and nutty-smelling. Let cool slightly, then mix with remaining ½ cup softened butter.
- Cream the sugars and butter: Beat until light and fluffy (about 2-3 mins).
- Add eggs and vanilla: Mix in eggs one at a time, then stir in vanilla and sourdough discard.
- Combine dry ingredients: In a separate bowl, whisk flours, baking soda, cornstarch, and salt.
- Mix wet and dry: Gradually fold in dry ingredients until just combined.
- Fold in chocolate: Use both chips and chunks for pools of melty chocolate.
- Chill for best results: Cover and refrigerate for at least 30 min (preferably overnight for max flavor).
- Bake: Scoop dough onto a parchment-lined sheet, spacing 2 inches apart. Bake at 350°F (175°C) for 12-15 min, until edges are golden and centers look just slightly underbaked.
- Cool: Cool on the sheet for 5 minutes, then transfer to a wire rack.

Expert Tips for Perfect Cookies
- Use an active sourdough discard for a stronger tangy flavor.
- Chill the dough for 30 minutes before baking to prevent spreading and intensify flavors.
- Don’t overbake! The cookies will firm up as they cool.
- Swap chocolate chips with chocolate chunks for rich, melty pockets in every bite.
- Add a pinch of flaky sea salt on top right after baking for a gourmet touch.
