In mixer or food processor, combine all ingredients, except water and ice cream, to form a fine cornmeal texture.
Slowly add water, pulsing, until dough begins to form. Remove from food processor. Gather into a ball, and roll out until flat. Wrap and chill for 15 minutes.
Preheat oven to 375° F (190° C).
On a lightly floured surface, roll out dough to desired thickness, and cut into shapes.
Place on a Sheet Pan lined with a Sheet Pan Liner, and bake 8–10 minutes.
Once cool, make your ice cream sandwiches with your favorite ice cream flavor.
