Vanilla yogurt is a type of yogurt that has been flavored with vanilla extract. The term "vanilla" in this context refers to the addition of a flavor rather than a specific ingredient, as it sometimes can be confused with. Vanilla yogurt typically tastes sweet and creamy due to the presence of sugar or other sweeteners used during the manufacturing process. It is often considered a healthier alternative to sugary desserts because it contains probiotics which are beneficial for gut health, protein, calcium, and vitamin D.
