This is the Default Recipe for chocolate-chip cookies. It's written a bit oddly here because I've re-expressed some of the ingredients in weight measure, to make it somewhat easier to put together in a hurry. I recommend Ghirardelli bittersweet chocolate chips for this recipe.

270 g flour
1 tsp table salt
1 tsp baking soda
½ lb unsalted butter
160 g brown sugar
145 g granulated sugar
2 large eggs
1½ tsp vanilla extract
½ cup chopped walnuts
12 oz chocolate chips (1 package)

Creaming method. Bake at 375°F for 12 minutes. Refrigerating the batter before portioning will reduce the spreading, if you prefer cookies that are smaller in diameter and more cakey.
