⭐ Greek Yogurt (Best Nut-Free Option)
1:1 (1 cup Greek yogurt per 1 cup sour cream)Greek yogurt has a similar protein and fat content to sour cream, as well as comparable acidity, which helps activate baking soda in quick breads. This acidity also contributes to a tender crumb and balanced flavor.
For best results, use full-fat Greek yogurt to match sour cream’s fat content and avoid thinning the batter. If the yogurt is too thick, stir gently to loosen before measuring.
The final bread will have a slightly tangier flavor but very close moisture and texture to the original recipe, with a tender crumb and good rise.
