You'd probably just be eating a handful of greasy French fries. It's a lot of work to pull out all the ingredients, mix up the batter, heat the oven, and then bake the cookies. How much easier it is to just spend time once a month and make up enough batter to last the month. Then just wrap it up and freeze it. Have them ready to go in the oven after you finish dinner to save energy and for dessert.
Cookies cost a lot of money in the store, and they taste so much better fresh from the oven.
Last week we talked about cooking whole chickens, and then cutting up the meat for several meals. See the feedback section for an even easier way to do this. Roasts are also good cooked this way. Divide up portions for slices, soups and stews, sandwiches, stir fry, stroganoff, casseroles, etc. It takes some planning, and it takes a day devoted to cooking, but doing this is a big money saver and makes the rest of the month go a lot easier.
