Mix both the flours, salt, baking powder well in a bowl. Add olive oil and stir to combine. Gradually add required warm water and knead to a smooth dough. You may need to add a bit more warm water, you want the dough to be smooth, not to sticky and not to tight. You can rest the dough for 15 minutes. Divide into 10 or 12 equal sized balls.
Roll into thin discs, dust when ever needed with all purpose flour. Heat a pan and toast the rolled tortillas on both sides in medium flame until slight golden dots starts to appear. It should be about 1 minutes on the first side and 30 seconds on the other time. Just wait for those golden dots!
