Make dough: Combine flour, salt, and baking powder. Add yogurt and stir to combine, adding water as needed. Knead into a smooth ball and let rest for 30 minutes.
Layer dough: Divide dough into 8 wedges. Roll out each wedge into a thin shape, brush with butter or oil, roll into a cylinder, then into a coil. Let rest for 15 to 20 minutes.
Cook flatbreads: Roll each coil into a thin round, brush with butter, and cook in a frying pan until golden brown. Keep warm in the oven. Repeat with remaining coils.
