Mix the flour, salt, and baking powder (if using) in the bowl of a stand mixer.
Fit the mixer with a dough hook and mix the dry ingredients at medium-low speed to combine.
While the mixer is running, pour in the water and continue to knead the dough until a dough forms. (If there are still dry spots of flour after 2 to 3 minutes of mixing, add some water, 1 tablespoon at a time.)
Transfer the dough to a floured work surface and knead it into a smooth dough.
Then, divide it into 4 pieces. Knead each piece by hand to remove air bubbles and roll them into a ball.
Add 1½ tablespoons of oil in an 8" non-stick cake pan or similar size pan. Then, place the dough in the pan and coat it generously with oil, making sure to cover all the surfaces.
Cover the pan with a lid and let the dough rest for at least 30 minutes or overnight in the fridge.
