A sugar cookie, or sugar biscuit, is a cookie with the main ingredients being sugar, flour, butter, eggs, vanilla, and either baking powder or baking soda. Sugar cookies may be formed by hand, dropped, or rolled and cut into shapes. They may be decorated with additional sugar, icing, sprinkles, or a combination of these. Decorative shapes and figures can be cut into the rolled-out dough using a cookie cutter.
