In a large bowl using an electric hand mixer or stand mixer, cream together butter, dark brown sugar and Karo® Light Corn Syrup. Beat until light in color, about 1 minute. Beat in the vanilla and salt. Add sifted flour into the bowl and mix until fully combined and the dough comes together. Add in the miniature chocolate chips and stir. Using a small scoop, scoop balls onto a parchment-lined sheet tray. Place in the refrigerator while making the chocolate mixture.
