Preheat oven to 350 degrees F. In a stand or electric mixer cream the butter and sugars until light and fluffy. Beat in eggs and vanilla slowly until well combined. In a large bowl combine the flour, baking soda and salt. Slowly add to wet mixture along with the chips until just combined. Scoop onto a parchment or silpat lined baking sheet and bake for 9-11 minutes or until cooked through to your liking. Cool on cooling rack and serve.
