1. Preheat the oven to 425oF (220oC) and line a baking sheet with parchment paper.
2. In a medium bowl, stir together the oat flour, baking powder, half of the salt and two- thirds of the dried rosemary. Mix in the water and knead a few times with your hands, adding additional water if needed to form a cohesive dough.
3. Place the dough between two sheets of parchment paper and roll it out until the dough is approximately one to two millimeters thick.
4. Cut the dough into approximately two-inch squares and transfer them to the prepared baking sheet. Poke each cracker with a fork, brush with the oil, and top with the remaining salt and dried rosemary.
5. Bake the crackers for 15 minutes until crispy and golden around the edges. Let cool completely on the baking sheet. Enjoy!
