Preheat the oven to 350 degrees F, or 160 degrees C. Butter a 9×13 inch pan. (or 8×8 for a thicker cookie)

In a bowl, cream together the butter, sugar, and vanilla until well-combined.

Combine the salt with the flour (unless you use salted butter), and mix it in the butter until it forms somewhat of a dough. (it may resemble breadcrumbs, or it may form a balled dough, it depends on the type of butter and flour you use.)

Add the chocolate chips until well-combined.

Press the mixture on the bottom of the pan.

Using a knife, cut the desired size pieces, and prick the cookies with a toothpick or a fork to prevent air pockets under the dough.

Bake 20-25 minutes or until lightly golden.

Right when the cookies come out of the oven, run a knife over the previous cuts. Cool for at least 5 (I know!) minutes before digging in.
