STIR flour with baking powder and salt in a medium bowl. Add oil, while stirring with a fork, until mixture is crumbly. Spoon a well in centre of flour mixture. Pour in water, gradually stirring, until dough comes together. Let stand, covered for 10 min.
DIVIDE dough into two portions and shape each into a disc. Cover one disc with plastic wrap while you work with the other disc. Cut disc into 8 equal wedges. Squeeze each wedge into a ball.
ROLL out each ball into a 5-in round.
HEAT a large non-stick frying pan over medium-high. Add tortilla. Cook until tortilla lifts away from pan and bubbles form, 30 sec to 1 min per side. Repeat with remaining tortillas.
