Preheat oven to 400F.
Line a baking sheet with foil and lightly spray with cooking spray; set aside.
In a mixing bowl, combine flour, baking powder and salt; whisk until thoroughly combined and set aside.
Combine water and oil in a separate bowl or cup; stir to combine.
Slowly add water mixture to the flour mixture.
Using a wooden spoon, or your hands, gently stir and mix until dough forms a ball; dough should be soft, but not sticky. Add more water if it's too dry, 1 tablespoon at a time. If it's too sticky, add more flour.
Lightly flour your work area and sprinkle 1/4-cup grated parmesan cheese over it.
Transfer dough to floured-work area and knead dough for 5 minutes.
Using a rolling pin, roll out the dough to a rectangle; long end should be rolled out to 12-inches.
Top dough with the remaining grated parmesan cheese and fresh ground pepper; press down on the toppings so they adhere to the dough.
Using a pizza cutter, cut out 1-inch wide breadsticks.
Transfer to prepared baking sheet and bake for 12 to 14 minutes, or until lightly browned on top.
In the meantime, combine salt and garlic powder in a small bowl.
Remove from oven and immediately brush with melted butter and sprinkle with salt and garlic powder mixture.
Set aside the breadsticks and keep them warm while working on the dipping sauce.
