*The easiest way to measure the flour is to add a full cup to the mixing bowl, then remove 1 tbsp from the bowl. All purpose flour will yield the crispiest results, but spelt or oat flour also work.Preheat oven to 310 F. Grease a cookie sheet. Combine first 5 ingredients in a large bowl. Stir in remaining ingredients to form a dough – it will be very dry at first, so keep stirring and breaking up clumps until it turns into cookie dough. You should not need more liquid. Roll balls. Place on the greased tray, then press down to flatten. (I rolled 16 balls, which turned into the cookies in the photos. They expand a lot as they cook, so leave room between cookies.) Bake 15 minutes, then let cool 10 minutes before removing from the tray. They also get crispier as they sit. As a general rule, crispy cookies are best stored in a cookie jar or glass container instead of plastic. If you try the recipe, be sure to leave a comment or rate it below!View Nutrition Facts
