In a bowl, combine all-purpose flour, salt, baking powder, and sugar.

Add oil and yogurt to the dry ingredients.

Knead the mixture with water to form a soft dough.

Cover the dough and let it rest for 7-8 hours or overnight.

Divide the dough into small, equal-sized balls.

Roll each ball into a circle with approximately 1/4 inch thickness.

Heat oil in a deep frying pan or wok.

Carefully slide each rolled bhatoora into the hot oil and deep fry until golden brown and puffed up.

Remove the fried bhatooras and place them on clean kitchen towels or paper napkins to drain excess oil.

Serve the bhatooras hot, immediately after frying, accompanied by chana masala.
