Preheat the oven to 390 degrees F.
Line two 9 x 13” baking pans and spray and set aside.
In a saucepan, bring the water to boil with the butter.
In a mixing bowl sift together the flour and salt.
Once the water and butter boil, add the dry ingredients to it and keep whisking.
A smooth, soft dough should form that doesn’t stick to the sides of the pan.
Remove from heat and add in the eggs, one at a time. You will have a shiny, glossy dough.
Divide the dough into the two baking pans equally. Spread it into a thin layer on the pan. It doesn’t have to be smooth, it should look rustic and uneven, like mountains, once baked.
Place in the oven and bake for 25 – 30 minutes.
Remove from oven and cool over a wire rack.
