ok, I was just looking at pics from last christmas and saw DD1 eating her first greek cookie. My grandma has made these every single year since before I can even remember, without them its almost not christmas!! I have made a few different cookies, sugar cut-outs, snickerdoodles and the like...I feel confident I can re-create it, but I need to replace literally every ingredient.....so I might need some help 
Heres the recipe/picture: http://www.fredshouse.net/archive/000450.html
the ingredients are:
1 lb. unsalted butter
2 egg yolks
1 T vanilla extract
4 C flour
1 t baking powder
1-2 boxes powdered sugar
So I'm thinking: spectrum shortening, flax eggs (will this work to replace just yolks?? any advice here?), GF flour blend of brown rice/white rice/tapioca, baking soda/cream of tartar for BP, white sugar/tapioca starch blended for the powder sugar.....that leaves the vanilla, is there any corn-free type out there, or a good sub (maybe cinnamon?)
Do you think its just too much to still be good? It also usually has almonds but my grandma said I could easily leave them out and that recipe doesn't even call for them so I'd say they aren't critical. I do have sunflower seeds I could sub but I feel like they would ruin it....
Anyways, any input? Am I just delusional? My grandma thinks its impossible without the butter....

-ing sweet white sorghum - it is giving me a fluffier, smoother texture than my brown rice was... i'm using the sorghum + potato starch though, can you use that?
