2 1/2 c. all-purpose flour
1/2 tsp. baking soda
1/4 tsp. salt
1 c. packed dark brown sugar
1/2 c. granulated sugar
4 c. (2 sticks) butter, softened
2 large eggs
1 (12 oz.) pkg. semi-sweet chocolate chips (about 2 c.)
2 tsp. vanilla extract

Preheat oven to 300°F. In medium bowl, combine flour, baking soda and salt. Mix well; set aside.

In a large bowl with electric mixer, blend sugars at medium speed. Add butter and mix to form a grainy paste, scraping down sides of bowl. Add eggs and vanilla extract; mix at medium speed until just blended. Do not overmix. Add the flour mixture and chocolate chips; blend at low speed until just mixed. Do not overmix. Drop dough by rounded tablespoonfuls onto an ungreased cookie sheet, 2-inches apart.

Bake 18 to 22 minutes or until golden brown. Transfer cookies immediately to a cool surface with spatula.

Makes about 3 1/2 dozen.
