The term "thick batter" refers to a type of mixture that is thick and viscous, similar in consistency to heavy cream or mayonnaise. This kind of batter is typically used for baking goods such as pancakes, waffles, and muffins, where it provides structure and texture to the final product. It can be made by combining dry ingredients like flour, sugar, salt, and baking powder with wet ingredients like milk or yogurt, eggs, oil, and flavorings such as vanilla extract. The thickness of the batter is determined by how much liquid is added to the mixture, so it can be adjusted according to personal preference or specific recipe requirements.
