Prepare the dough:

1. In a large mixing bowl, whisk together flour, salt, and baking powder until evenly combined.
2. Stir in oil and water. Mix well with a spatula until no dry flour is visible. Make sure to scrape off any remaining flour from the sides of the bowl.
3. Transfer the dough mixture onto a clean and dry surface. Knead the dough for 8-10 minutes until it turns into a smooth dough ball. You can also knead the dough on medium speed in a stand mixer for 6-8 minutes until smooth.
4. Cover the dough with plastic cling wrap and let it rest for 10- 15 minutes. This will help dough develop gluten strength.
5. On a clean surface, roll the dough into a 16-inch long log and use a bench scraper or knife to divide it evenly into 12-14 pieces. Shape each piece into a ball. Use a rolling pin to roll each ball into a 6-inch disc. 

Cook the tortillas:

1. Heat a large cast-iron skillet over medium heat until hot, about 1-2 minutes. Place one tortilla on the skillet at a time and cook for 45 seconds to 1 minute on each side until lightly browned. You should see the tortillas rise and form bubbles on top.
2. Repeat with all tortillas and cover with a clean tea towel to keep them soft.
