I did for some cookies from Norway. It dissipates after opening the package, so be warned.
When I went to use it again the next Christmas, the ammonia base had dissipated into nothing.
Also, there are righteous debates out there in Internet World on how to distribute it throughout the dough...dissolve in water and add or add to dry ingredients and mix in? The two camps are pretty fierce in their defenses.
I didn't notice that much of a difference, but then it was a new cookie for me.
