Add all-purpose flour, baking powder, and salt in a large bowl. Mix together until combined.

Add warm water and 4 tablespoons oil. Mix together with a spoon or your hands until the dough comes together.

Transfer the dough onto a clean working surface and knead the dough for 8 to 10 minutes, until the dough is smooth and elastic.

Roll the dough into a ball, place it in a bowl, cover with a kitchen towel and let it rest for 30 minutes.

While the dough is resting, cover a large plate with paper towels, fill a large saute pan with 1 to 2 inches of frying oil, and make the cinnamon sugar topping. Set aside.

Divide the dough into 8 separate pieces and roll each piece into a ball. On a lightly floured surface, use a floured rolling pin to roll out each ball into an 8 to 10-inch circle.

Heat the frying oil to 350°F. Fry each dough circle for about 60 seconds, turning once, until golden brown on both sides. Transfer to prepared plate to drain any excess oil. Sprinkle heavily with cinnamon sugar topping.

Combine granulated sugar and ground cinnamon in a small bowl.
