Preheat oven to 325 degrees, and line cupcake liners in a muffin pan.
Mix flour, baking soda, & salt in a small bowl.
Beat butter, sugar, brown sugar, & vanilla extract in large bowl until creamy.
Add eggs, one at a time.
Gradually add flour & beat until well-blended.
Stir in chocolate chips.
Place a big spoonful of cookie dough into each cupcake liner in muffin pan. Don’t press down on the cookie dough too hard – the cookie dough doesn’t have to be perfectly fitted into the liner.
Bake for about 15 minutes or until golden brown.
Remove from oven, and immediately make a shallow indentation in center of each baked cookie cup using the handle of a wooden spoon.
Cool for 10 minutes, and remove cookie cups from pan.
