The primary ingredient found in cakes is flour, which provides structure and stability to the dessert. Typically, all-purpose flour is used, but different types may also be utilized depending on the cake's desired texture and flavor. The flour is combined with other key ingredients, including sugar, eggs, butter, and leavening agents like baking powder or baking soda, to create a batter that rises during baking. The versatility of cakes allows for numerous variations, with flavors ranging from vanilla and chocolate to fruit and spice, making them a popular choice for celebrations and gatherings around the world.
