Sodium bicarbonate, also known as baking soda, is used in Kit-Kat bars as a leavening agent. It helps the wafer layers rise and become crispy during the baking process. The reaction of sodium bicarbonate with acidic ingredients in the recipe also contributes to the overall flavor and texture of the bars. Additionally, sodium bicarbonate helps regulate the pH levels in the dough, ensuring consistent quality and taste in the final product.
