The recipe works best with spelt flour, all purpose flour, oat flour, or all purpose gluten free flour.
1. If baking the cookies right away, preheat oven to 325° Fahrenheit (165° Celsius).
2. In a large mixing bowl or stand mixer, stir all dry ingredients well.
3. Stir in remaining ingredients to form a cookie dough texture. It will seem dry at first, and you may need to mix for up to a minute. For best results, do not add additional liquid.
4. Tightly roll the dough into cookie balls.
5. For chewier cookies, chill the dough balls in the refrigerator or freezer for one hour (or overnight). This step is optional.
6. Place the balls on two greased or nonstick cookie sheets, leaving space between each ball because they will spread while baking.
7. Bake on the center rack of the oven for 11 minutes.
8. Carefully remove pistachio chocolate chip cookies from the oven and let cool, during which time they continue to firm up.
9. Once cooled, store leftovers in a covered container for up to five days. Or freeze for longer term storage.
