The recipe came from a cookbook put together by our neighbor's real estate office over a decade ago.
7 ounces butter butter (I always use salted), softened (1 and 3/4 sticks)
2/3 cup brown sugar (I use whatever I have on hand, either dark or light, or a mixture)
1/2 cup white sugar
2 tsp pure vanilla extract
2 cups unbleached all purpose flour
1/2 tsp salt
1/2 tsp baking soda
1 12 oz bag semisweet chocolate chips
Preheat oven to 350
Cream the butter and add sugar, beating until well-mixed. Add the egg and vanilla, and mix for about 30 seconds.
In a separate bowl, stir together the flour, salt, and baking soda with a fork. Add to the butter mixture and stir gently until flour just disappears. Add chocolate chips and stir until evenly distributed.
Drop by rounded tablespoonfuls onto parchment or Silpat-lined cookie sheets and bake 8-10 minutes, until just beginning to brown on the edges.
