Strongly flavored eggnog sugar cookies?
Most egg nog cookie recipes I have seen don't call for eggnog at all or as you noted a scant amount. You get that true egg nog flavor from additional rum, vanilla and nutmeg.
I am not a fan of eggnog but this recipe came in third in our company wide cookie contest. Not bad considering there were over 50 entry's.
like foodieX2 suggests, my version includes eggnog in the cookies and in the glaze. i also amp up the spices a bit with a little extra cinnamon and nutmeg.
we've been saying all season we were gonna make more eggnog and jack daniel's cookies, but have yet to do so...
if you're interested and not quite satisfied with your test run tomorrow, i'm happy to post my recipe as well.
