Preheat oven to 425, line a baking sheet with parchment paper.

In a large bowl stir together the flour and baking powder and one teaspoon of the sea salt. Make a little well in the middle of the flour and pour in the water and olive oil. Stir with a wooden spoon until all combined and can be formed into a ball.

Flour a board or flat surface and place dough ball on the floured surface and roll it thin to about 1/4 inch thickness and place onto parchment lined baking sheet. I didn't have a board big enough so I split the dough into two pieces and rolled them out and then pressed them together when I placed them on the parchment paper. Sprinkle remaining sea salt on top of the dough.

Bake for 20 minutes, then check to see the color, you want it a golden brown. If you need to bake the crackers a few more minutes for them to be done, do so.

Remove from oven and allow to cool for 10 minutes.

Lift the parchment paper out of the baking sheet, and slide the big cracker onto a cutting board. Now cut into smaller cracker pieces and serve!
