⭐ Sour Cream (Best Nut-Free Option)
1:1 (1 cup sour cream per 1 cup Greek yogurt)Sour cream has a comparable fat content and acidity level to Greek yogurt, which helps activate the yeast and tenderize the dough proteins, resulting in a soft crumb. Its thickness ensures the dough maintains proper hydration without becoming too wet.
When substituting, use the same volume as Greek yogurt. Be mindful that sour cream can sometimes be slightly less tangy, so a small splash of lemon juice can be added if desired to mimic the tang.
The final cinnamon rolls will have a very similar texture and flavor profile, maintaining the characteristic moistness and slight tanginess that Greek yogurt imparts.
