In a large bowl, whisk together the flour, baking powder and salt. Add water and oil. Mix till a dough is formed. Dough should be soft and Playdoh-like in texture, but not sticky. Add more flour as needed, 1 tablespoon at a time.
Tip dough onto a clean work surface knead for 1-2 minutes till smooth. Cover with kitchen towel. Rest for 10 minutes.
Divide the dough into 12 equal parts. Roll into balls. Heat a large nonstick pan over medium heat.
Roll out one piece of dough into roughly 6 to 8-inch circle. Cook the tortilla for about 1 minute then flip and and cook for another 30 seconds.
Repeat with the rest of the dough and keep cooked tortillas warm under a clean kitchen towel until it is ready to be served.
