Preheat the oven to 375° F.
Cream together the shortening, coconut oil, sugars and vanilla. I usually use a mixer for everything, but you can do it by hand, too.
Fold in the eggs and mix well.
In another bowl, sift (or just mix really well) the dry ingredients.
Add the dry ingredients a little at a time to the wet ingredients and mix well.
Stir in the chocolate chips. If you are patient, chill the dough for a few hours or overnight. This helps prevent spreading. I am not patient, lol.
To bake, grease your cookie sheets or line with parchment paper or silicone liners. Greasing is what the original recipe calls for, but I prefer the results from lining the sheets.
Form your cookies (I use a 2 tablespoon sized scoop, but you can make them bigger or smaller) and place them two inches apart on the sheets.
Bake for about 8-10 minutes, keeping a close eye on them during the last few minutes. You want them to be golden and not doughy in the middle.
Cool for a few minutes on the sheets before removing them.
