Known as Gifts in a Jar, Cookies in a Jar, or even Sand Art Cookies, these fun projects are to make a cookie mix that you can give to recipients to make their own homemade baked goods (and beverages) at their leisure. Different colored ingredients are typically layered inside a mason jar, in a manner much like that of the the popular children’s craft known as Sand Art. These Gifts in a Jar recipes are fun, thoughtful and inexpensive gifts to make for friends, teachers, and gift exchanges.
