Chocolate Chip Cookies
This is a large recipe, might be good to make half a batch. Also I make the cookies smaller than suggested.
350 degree oven, grease cookie sheets. Yield: 1 1/2 dozen 5-inch cookies, or a lot more smaller cookies.
3 1/2 cups flour
1 1/4 teaspoons baking soda
1 1/2 teaspoons baking powder
1/2 teaspoon salt
2 1/2 sticks (1 1/4 cups) butter
1 1/4 cups light brown sugar
1 cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
1 1/4 pounds bittersweet chocolate chips
Sift flour, baking soda, baking powder and salt into a bowl. Set aside.

Using a mixer, cream butter and sugars together until very light, about 5 minutes. Add eggs, one at a time, mixing well after each addition. Add vanilla and mix well. Add dry ingredients and mix until well combined. Add chocolate chips and mix well. For best results press plastic wrap against dough and refrigerate for 24 to 36 hours. Dough may be used in batches, and can be refrigerated for up to 72 hours.

Scoop mounds of dough (the size of generous golf balls) onto baking sheet, and bake until golden brown but still soft, 18 to 20 minutes. Transfer sheet to a wire rack for 10 minutes, then slip cookies onto another rack to cool a bit more.
