In a blender or food processor, blend the oats until it has reached flour consistency.
Place the oat flour, whole wheat flour, egg, coconut oil, water, cinnamon, and ginger in a mixing bowl.
Use a mixer to combine all the ingredients until well blended. You may need to use your hands to get everything well combined.
Using a rolling pin, roll out the dough to about ¼ to ½-inch thickness, according to your preference.
Use a cookie cutter to cut out the treats and place them on the prepared baking sheet.
