⭐ Greek Yogurt (Full Fat) (Best Gluten-Free Option)
3/4 cup yogurt per 1 cup butterGreek yogurt contains water and protein but lacks fat compared to butter, so reducing the amount used compensates for moisture differences. The acidity can tenderize gluten, producing a softer, cakier sugar cookie rather than the traditional crisp texture.
Use full-fat Greek yogurt for richness and reduce other liquids slightly to maintain dough consistency. Expect a tangier flavor profile and softer bite.
This substitute changes the cookie’s texture noticeably, making it less crisp and more cake-like, which may or may not suit traditional sugar cookie expectations.
