Shortbread and sugar cookies are often confused for one another, thanks to their perfect sweetness and satisfying crispness. There are a few differences in ingredients, taste, texture and traditional decorations.
Sugar cookies often have many ingredients, including eggs, vanilla, salt and a leavening agent such as baking powder or baking soda. Traditional shortbread has four ingredients at most: sugar, butter, flour and sometimes vanilla.
Shortbread and sugar cookies are often chilled and then rolled and cut with cookie cutters. But sugar cookies can also be made in the style of a drop cookie without being rolled out.
Texture and Taste
Shortbread is almost always thicker and denser than a sugar cookie. It also contains more butter, so the taste is richer.
Baking times don't differ much, but shortbread is often baked longer than sugar cookies by 2 to 5 minutes.
Shortbread is usually eaten plain and left undecorated because of its rich flavor, while bakers often frost and decorate sugar cookies with sprinkles or granulated sugar.
