Preheat oven to 375 degrees F.

Cream together the butter and sugars in a large mixing bowl. Add the egg and vanilla and mix until creamy.

In a medium bowl, stir together the flour, baking soda and salt. Add to the butter mixture and blend well. Stir in the chocolate chips.

Roll the dough into balls and place on a parchment-lined or lightly greased cookie sheet. Chill the cookie sheet and dough balls in the refrigerator for about 20 minutes.

Bake 10 to 12 minutes, or until cookies start to brown lightly around edges.

To make your cookies pretty like mine, set aside some of the chocolate chips and press them onto the top of each cookie right after coming out of the oven!
