SIMPLE Basic Butter Cookie / 3 ingredients (home-baking, icing cookie, sugar cookie)

I made the simplest and most basic butter cookie among cookies. Even beginners can make them easily. The dough uses eggs, butter, salt, sugar, vanilla, flour, and baking powder. I added extra eggs to keep the dough from being too wet and used a small amount of vanilla to avoid a strong scent. All-purpose flour works fine. These cookies are perfect for icing and baking.
