⭐ Sour Cream (Best Gluten-Free Option)
1:1 (1 cup sour cream per 1 cup Greek yogurt)Sour cream works well because it has a comparable fat content, acidity, and moisture level to Greek yogurt, which helps activate baking soda and contributes to a tender crumb. The acidity also balances the sweetness and enhances flavor.
For best results, use full-fat sour cream and ensure it is well mixed before incorporating. Avoid overmixing the batter to maintain a light texture.
The final quick bread will have a very similar texture and flavor profile, with a slight increase in richness due to the higher fat content in sour cream compared to Greek yogurt.
