I must agree with RY that it’s unlikely that the Chanukah cookies were developed independently of Christmas cookies.
That doesn’t necessarily make it Chukas haGoyim. The goyim don’t attach any ritualistic or superstitious significance to the cookies, they just do it for fun. It’s just an ironic way of celebrating the holiday that memorializes our resistance to assimilation.
And, again, why hasn’t anyone brought up gifts yet?
