Preheat oven to 375 degrees.
In a small bowl, whisk together all-purpose flour (sifted, spooned and leveled), baking soda and salt.
In a large mixing bowl combine butter, granulated sugar, brown sugar, and vanilla extract. Use a hand mixer to beat until creamy.
Add eggs, one at a time. Beat well after each addition.
Gradually beat in flour mixture one cup at a time.
Use a large spoon to stir in chocolate morsels.
After preparing dough, cover bowl. Refrigerate for 4 hours up to overnight before baking. Chilled dough is perfect for making soft, chewy cookies. Remove chilled dough from fridge. Continue with next step.
Drop onto ungreased baking sheet by rounded tablespoon. Bake 8 to 10 minutes OR until edges are golden brown and chocolate chips have melted.
Chewy cookies will look like they're not done. Immediately remove pan from oven. Cool cookies in pan 2 minutes. Remove and continue cooling on a rack.
Makes about 60 cookies.
