Preheat oven to 375 degrees

Beat butter, brown sugar, sugar, and vanilla in a large bowl until creamy. Add eggs and beat well. Gradually beat in flour, baking soda, and salt. If the mixture seems too soft add another 1/2 cup flour (most batches need it) then add chocolate chips and mix well. Use a medium scoop and place a scoop full onto pan for each cookie.

Bake cookies 9 1/2-10 mins for the first pan. Let each pan of cookies cool for one minute on pan and then move cookies to a wire cooling rack to cool completely. Makes 4 dozen cookies
