Store these cookies in an airtight container along with a slice of bread to keep them soft and chewy.
1 1/3 cups butter
1 1/2 cups brown sugar
1 cup granulated sugar
1 tbsp vanilla extract
3 3/4 cups flour
1 1/4 tsp table salt
1 tsp baking soda
12 oz pkg semisweet chocolate chips
Cream the butter ans sugars starting on low speed, gradually working your way up to high speed, until the mixture is light and fluffy, about 3 minutes. Scrape the sides of the bowl. Add the eggs and vanilla and beat on low speed until blended. Beat on high speed until light and fluffy, about 1 minute. Scrape the sides of the bowl.
In another bowl, combine the flour, salt and soda and add to the creamed mixture, stirring with a wooden spoon until just blended. The dough will be stiff. Stir in the chocolate chips.
