My mother-in-law gave me an enormous cookie scoop for Christmas one year, so 12 cookies is plenty for a week for one person (the kids and I aren't eating cookies right now). I make a large batch of cookies once a month or so, scoop and freeze on a cookie sheet, pop off, and then bake 12 at a time (how many my cookie sheet holds).
The recipe, roughly:
3 sticks butter (I still want to try this with coconut oil, at least part, and will next time)
1-1/2 cups sugar
Cream butter and sugar and add in
4 eggs
2 tsp vanilla extract
1 tsp sea salt
Mix well
Add in
3-4 cups flour (depending on if you like flat or cakey cookies
1 tsp baking soda
1/4 tsp cream of tartar
2 cups chocolate chips
I bake at 375, 15 minutes
