⭐ Greek Yogurt (Best Gluten-Free Option)
1:1 (1 cup Greek yogurt per 1 cup sour cream)Greek yogurt works well because it has a similar fat content and acidity level to sour cream, which helps tenderize the gluten and activate baking soda or powder. The thick texture ensures the batter consistency remains stable.
For best results, use full-fat Greek yogurt and avoid overly watery varieties. If the yogurt is too thick, you can thin it slightly with milk, but keep the batter consistency similar to the original recipe.
Cupcakes made with Greek yogurt will have a slightly tangier flavor and moist, tender crumb comparable to those made with sour cream, often with a subtle increase in protein content.
