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

Make a well in the center of the dry ingredients and add warm water, plain yogurt, and melted butter or ghee. Mix until a dough forms.

Transfer the dough to a floured surface and knead for about 5 minutes, until smooth and elastic.

Place the dough in a greased bowl, cover with a kitchen towel, and let it rest for 1-2 hours, or until doubled in size.

After the dough has risen, divide it into 6-8 equal portions. Roll each portion into a ball.

Preheat a skillet or griddle over medium-high heat.

Roll out each dough ball into a thin circle or oval shape.

Place the rolled-out dough on the hot skillet or griddle. Cook for 1-2 minutes on each side, until bubbles form and the naan is golden brown and slightly charred.

While the naan is still hot, brush it with melted butter or ghee and sprinkle minced garlic and chopped cilantro, if desired.

Serve the garlic naan warm with your favorite Indian dishes or enjoy it as a snack on its own.
