Sour Cream (Best Option)
1:1 (1 cup sour cream per 1 cup Greek yogurt)Sour cream works well because it has a similar fat content, acidity, and viscosity to Greek yogurt, which helps activate baking soda and maintain moisture in the batter. The acidity contributes to a tender crumb and slight tanginess that balances the sweetness.
For best results, use full-fat sour cream and avoid overly watery varieties. Stir well before measuring to ensure even consistency.
Pancakes made with sour cream will be nearly indistinguishable from those made with Greek yogurt, maintaining fluffiness, moisture, and a pleasant tang.
