Frequently Asked Questions:
1. Can I use an active sourdough starter instead of discard?
Yes, but it may make the cookies slightly puffier since the active starter has more leavening power.
2. Can I make these cookies dairy-free?
Yes! Substitute butter with coconut oil or a dairy-free alternative, and use dairy-free chocolate chips.
3. Do I need to let the dough rest before baking?
It’s not required, but chilling the dough for 30 minutes can enhance flavor and texture.
4. Can I add nuts or other mix-ins?
Absolutely! Chopped nuts, dried fruit, or even a sprinkle of sea salt can be great additions.
5. Why use sourdough discard in cookies?
The discard adds flavor, moisture, and a slight chewiness to the cookies while reducing food waste.
