These cookies are by far "The Best" Sugar Cookies I have ever had, and the amazing flavor is in the secret ingredient :) I guarantee if you do make them, you will never use another recipe. Try them and see for yourself! They are delicious plain or decorated with frosting, or glaze and holiday jimmies or sprinkles or colored sugar granules. You can substitute lemon or lime peel in place of the orange peel if you wish. They are all awesome! You can easily double this recipe to make a larger amount of cookies for the holidays! The amount of cookies really depends on the size of the cutters you use, so it is only a guesstimate. The cooking time is for 2 sheets of cookies.
