Walnut-shaped cookies are small, bite-sized treats that are shaped to resemble whole walnuts. These cookies typically have a buttery and crumbly texture, often infused with flavors like vanilla or almond extract. They may also contain chopped walnuts or other nuts for added crunch and flavor. After baking, they are often dusted with powdered sugar to enhance their appearance. Walnut-shaped cookies are a popular choice for holiday baking or as a sweet snack any time of year.
