Sift together dry ingredients and set aside. Cream together the melted butter and sugars until well blended. Beat in vanilla and eggs until light and creamy. Add dry ingredients and mix until just blended. Stir in chocolate chips using a wooden spoon. Drop onto cookie sheets lined with parchment or silpat using a 1/4" disher (cookie/ice cream scoop) or measuring cup.

Bake at 325 for 15 to 17 minutes or until edges are lightly golden. Allow to cool slightly before transferring to a wire rack to cool completely.
