Preheat oven to 350 degrees. Peel, core, slice and mince the apple, use a food processor. In a large bowl, combine the apple, honey, water, cinnamon, and oatmeal. Gradually blend in wheat flour, adding enough to form a stiff dough. Spoon the dough by rounded teaspoonfuls onto a ungreased baking sheet, spacing about 2 inches apart. Using the bottom of a glass dipped in flour, flatten each spoonful into a circle. Adjust the size of circle to how big of a treat you want to give. Bake for 30 minutes. Remove from oven and flip each cookie to brown evenly on both sides. Reduce oven to 325 and bake another 15 minutes.
