A cookie is a small, flat, sweet, baked good, usually containing flour, eggs, sugar, and either butter, cooking oil or another oil or fat. It may include other ingredients such as raisins, oats, chocolate chips or nuts.

Many people enjoy eating cookies, and will typically go to a store or bakery to buy them if they don't opt to make them at home. However, the Internet has created an outlet for people to buy cookies online, from all parts of the country. Selling cookies online is a way to potentially make money doing something you love, and the start-up and operating costs are much lower than running a traditional bakery. However, you will still need to adhere to your local laws, and work hard to attract potential customers.
