I'm not fond of the typical sugar cookie. Too crisp for me I guess and not much flavor.
I found a basic cookie dough recipe a few years back that I can modify to add all sorts of stuff as the mood fits me. Oatmeal, raisins, dried cranberries, apples or cherries and various spices all work well. Of course I can't find it right now to post.
One trick I discovered from a few searches when I wanted cookies and didn't have any eggs on hand ..... applesauce or bananas can also be used in place of eggs as the binder. They do the same thing 'chemically' when mixed into the flour to make the batter. Oh, I also mixed cornmeal and flour together to make something a little different that adds a bit of grit and a different taste.
