Tips for the Best Sourdough Oatmeal Cookies
- Use unfed or fed sourdough discard – This recipe works best with discard from a mature starter. No need to feed it! But if the only thing you have on hand is active sourdough starter then use it.
- Chill the dough for deeper flavor – If you have time, refrigerate the dough for a few hours or overnight before baking. This enhances the tangy sourdough flavor and makes the cookies more chewy.
- Customize it – Swap chocolate chips for raisins, cranberries, or even white chocolate. Add nuts for extra crunch!
- Storage & Freezing – Store in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months.
Why Add Sourdough Discard to Cookies?
Sourdough discard adds richness, moisture, and a slight tang to these cookies without making them taste sour. It also helps create a chewy texture and adds extra depth of flavor—something you won’t get from regular cookies!
