In a bowl, combine the whole wheat flour, sugar, baking powder, yogurt, and salt. Add water as needed and knead into a soft dough.

Sprinkle nigella seeds on top and, if desired, add chopped cilantro. Press them onto the dough with wet hands.

Place the naan on a hot skillet. Once the bottom is cooked, flip the skillet to cook the top side directly over the flame until done.

Your naan is ready to serve.
