Clay's Chocolate Chip Cookies

These are Clay's cookies that we happen to make ALL the time. Maybe I'll add a picture later, but for now, here is the delicious recipe:

4 cups flour
1 1/4 teaspoons baking soda
1 1/2 teaspoons baking powder
3/4 teaspoon salt
2 1/2 sticks butter (1 1/4 cups) unsalted butter (I only Use 2 1/4 sticks, and sometimes it's margarine)
1 1/4 cups brown sugar
1 cup plus 2 tablespoons granulated sugar
2 large eggs
2 teaspoons vanilla extract
chocolate chips (1 cup or more--your preference)

Preheat oven to 350 degrees.

1. Mix flour, baking soda, baking powder, and salt and set aside.
2. Using mixer, cream butter and sugars until very light, about 5 minutes.  Add eggs one at a time, mixing well after each addition.  Stir in vanilla. Stir in dry ingredients, just until incorporated.  Mix in chocolate chips. 
3.  For best cookies, scoop out large generous golf-ball sized balls of dough onto the baking sheet (seriously, these are big--should make around a 5 inch cookie).  Back for 18-20 minutes.  Let cool on sheet for several minutes, then transfer to rack.  A smaller size will change the time. and you'd just have to do trial and error.  Presumably a normal cookie size would do about 10-11 minutes.
