macha

Anyone made macha or sesame seed shortbread?

I have seen maki's recipe for macha icing on black sesame cookies, but I'm thinking that the texture, with only whole wheat flour, would be too tough/flat for me. I am tempted to try a shortbread (flour, butter sugar) version of this. Has anyone seen/tried a good recipe for sesame or green tea shortbread ? Thank you
