Line either a baking sheet or prep your pizza stone and start pre-heating your oven to 400 degrees F.
In a large mixing bowl, combine the whole wheat pastry flour, baking powder, and sea salt, and whisk together until thoroughly combined.
In a separate bowl, combine water and olive oil in and stir to combine.
Slowly add water mixture to the flour mixture, stirring to incorporate. Mix together until a dough forms. The dough should be soft, but not sticky. You can add a little more water if it's too dry, a tablespoon at a time. If it's too sticky, just add a little more flour.
Once the dough has formed into a ball, knead the dough for 5 minutes. Then, roll the dough out into a large circle using a rolling pin or by stretching it with your hands.
Lightly brush the dough with olive oil, and then transfer it to the oven for 10 minutes, or until very lightly browned.
While the crust is in the oven, prep the rest of the pizza toppings, as desired.
Add your desired toppings, and then place back into the oven for another 10-15 minutes, until the edges of the crust are golden brown, and the cheese is melted and bubbly.
