why make this recipe
Sourdough Brownie Cookies are a delicious combination of two beloved treats: brownies and cookies. They provide a chewy texture with a rich chocolate flavor, making them a favorite for many chocolate lovers. Plus, using sourdough discard not only cuts down on waste but also adds a hint of tanginess to the sweetness, creating a unique flavor that you won’t find in regular brownies or cookies. These cookies are easy to make and perfect for any occasion, whether you need a sweet snack or a dessert to share with friends and family.

FAQs
1. Can I use regular sourdough starter instead of discard?
Yes, you can use a regular sourdough starter if it’s active, but it’s best to follow the proper feeding schedule to ensure your starter is at its peak.
2. How do I know when the cookies are done baking?
The cookies should have set edges while the centers are still soft. Once they cool, they will firm up.
