A cookie bar is a type of dessert that is made by baking cookie dough in a rectangular pan, creating a dense and chewy bar-like treat. The dough is typically made with ingredients similar to those used in traditional cookies, such as flour, sugar, eggs, butter or oil, with add-ins like chocolate chips, nuts, or dried fruits. However, cookie bars usually have a higher ratio of dough to mix-ins, resulting in a denser, more uniform texture. Cookie bars can be customised in many ways. For example, some recipes might call for a layer of frosting or glaze on top, while others might incorporate different types of mix-ins, such as caramel, butterscotch chips, or peanut butter. Cookie bars are often cut into squares or rectangles for easy serving, and they can be enjoyed as a snack or dessert on their own or paired with ice cream, whipped cream, or other toppings.
