⭐ Greek Yogurt (Best Gluten-Free Option)
1:1 (use equal volume to sour cream)Greek yogurt has a similar acidity and fat content to sour cream, which helps activate baking soda and tenderize gluten, maintaining the cookie’s soft, chewy texture. Its moisture content is close enough to sour cream to avoid dough hydration issues.
For best results, use full-fat plain Greek yogurt and ensure it is well stirred to avoid lumps. Avoid using flavored or sweetened varieties as they can alter the cookie’s flavor profile.
Compared to sour cream, Greek yogurt produces cookies with a slightly tangier flavor and similar moisture, preserving the classic chocolate chip cookie texture and balance.
