Preheat oven to 425 degrees. Grease a baking sheet and set aside.
Sift together flour, baking powder and 1 tsp salt into a large bowl. Stir in water and knead in the bowl for a couple of minutes. The dough will be a little sticky.
Turn out the dough on a greased baking pan and press it out until it’s approximately 1/2 inches thick. Coat the dough with olive oil, then sprinkle with cayenne pepper, garlic powder and 1/2 tsp salt. Press the chopped bacon into the top.
Bake for 20 minutes. Sprinkle with the parmesan cheese and bake another 5 minutes until golden brown.
