This is what I came up with--as close to perfection as I can get: I use Pamelas baking mix as a substitiute for the flour (straight across) and it also replaces any salt, xanthan gum, baking soda and powder (if it calls for it) and then decrease the butter by 2/3 (!!) So if it calls for 1 cup, use 1/3cup. (I used ~6tbs). Refrigerate the dough for about an hour and then bake at 350, on parchment paper, for 10-12 minutes, remove when a little brown around edges and still gooey in center, let sit on pan for ~5minutes before transferring to cooling rack. They are perfectly crisp on the edges and soft and delicious on the inside.
My progression of making chocolate chip cookies is as follows:
1) Used Pamela's mix and recipe. I refrigerate awhile and only bake about 12 cookies, freeze the rest in a log for future baking. (good)
2) Used the Tollhouse recipe, except used about 2/3 Pamela's, 1/3 sorghum flour, and a tablespoon or two of almond flour, and 1/2 butter, 1/2 Crisco. (better)
3) Used the Tollhouse recipe, used only Domata flour, baked as pan cookies (as opposed to individual) on parchment paper (THE BEST!) My non-Celiac daughter chose to bring these (over Krispy Kreme's) to school for her birthday treats.
Domata is an all-purpose blend that includes Xanthan and is designed to sub cup for cup for regular flour in recipes. Our local grocer is carrying it by request in their gluten-free section. It costs $15 for a 5-lb bag. You can get it mail order for about the same price by the time you include shipping and handling.
