Greek Yogurt (Best Option)
1:1 (1/4 cup Greek yogurt per 1/4 cup sour cream)Greek yogurt has a similar protein and moisture content to sour cream, which helps maintain the structure and moisture balance in energy balls. Its natural acidity also replicates the tangy flavor profile, enhancing taste.
For best results, use plain, full-fat Greek yogurt to closely match the fat content and texture of sour cream. Avoid flavored or low-fat versions as they can alter taste and texture.
Compared to sour cream, Greek yogurt may yield slightly firmer energy balls with a subtle difference in flavor, but overall it preserves the intended mouthfeel and binding properties.
