Preheat the oven to 350°F.
Place the oat flour in a mixing bowl and add wet ingredients and blend well using a hand mixer, a spoon or your hands.
The dough will be sticky. Let it sit in the bowl for 15 to 20 minutes until it stiffens up a little.
Place the dough on a flat surface lightly dusted with oat flour.
Roll out the dough until about 1/3-inch thick.
Using your favorite cookie cutter, cut out as many shapes as possible. If the dough is still too sticky to roll, add a little more flour to make it drier.
Gather the dough scraps, press them together to form a dough ball, then re-roll and cut out the treats until all the dough is used up.
Place the cutouts on a baking sheet.
Bake at 350 degrees for 20 to 25 minutes.
Transfer the baked treats to a wire rack and cool them to room temperature.
