Brownie batter is a thick, chocolatey mixture made primarily from ingredients like flour, sugar, cocoa powder, eggs, and butter. It is the base for making brownies, a popular dessert known for its fudgy texture and rich flavor. The batter can be mixed by hand or with an electric mixer until smooth, and it often includes additional ingredients like nuts or chocolate chips for added texture and taste. Before baking, brownie batter is typically poured into a greased pan and spread evenly. Once baked, it transforms into delicious brownies, which can be served warm or cooled. Many people enjoy licking the spoon or bowl after mixing, as the raw batter is often considered a tasty treat, though it is important to note that consuming raw eggs carries some health risks.
