Greek Yogurt (Best Option)
1:1 (1 cup Greek yogurt per 1 cup sour cream)Greek yogurt has a similar fat content and acidity to sour cream, which helps tenderize the dough and activate leavening agents like baking soda. Its creamy texture ensures moisture retention, contributing to soft, fluffy rolls.
For best results, use plain, full-fat Greek yogurt and stir it well before measuring. If the yogurt is too thick, thin it slightly with a teaspoon of milk or water to match sour cream’s consistency.
Compared to sour cream, Greek yogurt may impart a slightly tangier flavor but maintains the desired moisture and tenderness, resulting in cinnamon rolls that are very close in texture and taste to the original.
