Any ideas for simple cookie recipes that can be prepared with few ingredients?

I found out very last minute that a friend is having a housewarming/birthday party this evening. I figured it’d be nice to get her a serving dish for her new house and fill it with some homemade cookies, however I am very, very limited in ingredients.

I have:
-Butter
-White granulated sugar
-Brown sugar
-Ground cinnamon
-Whole wheat flour
-Baking powder
-Eggs
-Milk
-Salt
-Vanilla
-M&M’s
-Chopped walnuts

I was thinking Snickerdoodles but, unfortunately, I do not have any cream of tartar and most recipes call for that.

Any ideas?

Does anyone have any good cookie recipes?

Mostly looking for recipes that have items found around the house. I’m babysitting and my lil brother wants homemade cookies. I can’t go to the store and buy any ingredients. I don’t have any baking soda or yeast, but I have a ton of other cookie ingredients including peanut butter, almond extract, chocolate (not chocolate chips, but hershey’s chocolate), oats, flour, sugar, salt, etc. Please tell me a good recipe (if there is a low fat recipe that would work too because my mom said not to give my little brother too much sugar).
