Light buckwheat flour is perfect for baking and creates that lovely crumbly texture in these chocolate chip cookies. However, I have used a combination of light and dark or only dark buckwheat flour before, which also works fine. Just know that the latter gives a darker-colored cookie and perhaps a slightly more earthy buckwheat taste.
